Recently, I was given a task to advise HANA roles based on requirements given by my colleague and senior David Vitali

This was an opportunity to read and learn about HANA security while completing this task. However, soon I found that I would need to read several guides to fulfil the requirements and learn about different type of security privileges and roles. So, I decided to gather the information from different guides and put it into one quick reference (or cheat sheet). I can now quickly refer to document whenever I need to understand, create, update or review security for roles and users. I have also found that some of privileges available in our current system (i.e. SP06 Rev64) are missing from guides which are written for SP06. For example: DEVELOPMENT  privilege is not mentioned anywhere in guides.

Please do comment or suggest the updates if I am missing them. I will add them to quick reference. If possible, please do suggest roles for various purposes. Hopefully, I will keep getting such exposure and share.

EDITED on 17/10/2013: Added SQL syntax for inbuilt _sys_repo procedures. I have been using them for granting access and used once for revoke. Good for granting multiple privilege in one go.

Disclaimer:

This document has been prepared solely for information purposes for the use of the recipient and without any commitment or responsibility on my (Angad Singh) part.

This is a pretty trivial thing but I keep looking for the URL and can't find it, so it can't be that easy to find. So I thought I'd write a document so I can find it in future. Maybe it helps someone else :-)

As a bonus, we then go on to configure the Developer perspective and build our first Hello World XS app using the new HANA SP07 Team functionality.

There is no current supported version of SAP HANA Studio for Mac as of SP07 - we hope for a version to come in the future. But, there is an internal build that SAP use, and our friends at the SAP HANA Developer Center made it available for us to use! It is available on the SAP HANA Developer Center page. This version is usually a few revisions behind the current revision of SAP HANA Studio, and is only updated from time to time, and explicitly offers you no formal support.

You can go ahead and download it now! I find the SAP HANA Developer Center gives me great download speeds, so it's downloaded whilst I wrote this paragraph! It will appear in your downloads as a GZ file:

Double click on the GZ file and it will quietly create a folder called hdbstudio, which you can navigate into. Be careful, because this folder will have an older date so you may not spot it!

I copy this top level folder into the Applications folder - HANA doesn't do this automatically, at least for now! I already have a version there, so it prompts me to copy it.

Then, I open the hdbstudio folder and drag the hdbstudio Application onto my taskbar. It looks like this:

If you are running a new-ish version of Mac OS X it won't let you run this file - it will give you this error message: "hdbstudio" can't be opened because it is from an unidentified developer.

Not to worry... press Apple --> System Preferences --> Security & Privacy. You should see the following:

You can go ahead and click Open Anyway!

Click Open. Yay... along comes HANA Studio!

Here it is in all its glory...

If you're new to SAP HANA, here's how to connect. Click Open Administration Console --> Right click and click Add System

Enter the system details, username and password and click "Save to Secure Storage"

Now you have your HANA system, with the Rev.68 version on Mac you should be able to use the developer tools without regi.exe - and so do native development. Select Window -> Open Perspective -> Other -> SAP HANA Development and press OK:

Select Repositories -> Create Repository Workspace:

You can now browse the repository workspace on your HANA Server. Here is some SAP-delivered content:

Now you can click the Project Explorer View and select New -> Project:

We have to drill in to find the HANA XS Project:

As of HANA SP07 I can just give the project a name... and select the default location.

Now I have to share my project back to the HANA Server using the Eclipse Team functionality. Right click your project and select Team --> Share Project:

You can give it whatever name you want, depending on where you want your project to end up in the SAP HANA Repository. I choose a location provided to me as a test area. Note that by default the project will create a subfolder, so my location will actually be trainingContent.trainees.USER11.xstest:

That's it! My Project is configured and ready to go! Note that my project appears with a * next to it - meaning "unsaved", until we have some active content.

For bonus points... let's go ahead and configure a simple Hello World scenario. Right click your project, select New -> Other and browse for the XS Application Descriptor File:

Go through the wizard and finish up - don't change any settings. Then right click, select Team -> Activate.

Repeat the same with the XS Application Access file - and activate it. Your project should look like this, and you're ready to go:

Now let's create a simple index.html - right click your project, select New -> File -> index.html. It will open in a browser so close the browser, right click index.html and select Open With -> Text Editor.

Then type Hello World... Save... and activate. We're done! Our Hello World example is exactly where you would hope. Note that it is our server name, followed by port (8000+system number), then our repository location that we configured, our project name, and index.html. Super simple!

http://saphana1:8005/trainingContent/trainees/USER11/xstest/index.html

Final Words

I hope this helps someone get up to speed with HANA development fast! Note that if you are a HANA SP06 developer then this process is slightly different - and much simpler and more sensible.

A quick thanks to Rich Heilman and @Thomas_Jung for helping me out when I came to configure my first system. The differences between SP06 and SP07 left me confused.

Happy developing!

SAP Landscape Transformation (SLT) is used to transfer (load/replicate) data from source to target system.

After configuration set-up in SLT, in HANA studio we can load or replicate data using Data Provisioning link. In Data provisioning window, we have the following options:

Load:Starts an initial load of data from the source system. The procedure is a one-time event. After it is completed, further changes to the source system database will not be replicated. No data base triggers will be created. No logging of table occurs.

Replicate:It starts the initial load (if not done before) and also takes care of the delta changes. Database trigger and related logging table are created for each table in the source system.

Stop replication: Stops any current or replication process for a table. It removes the database trigger and related logging tables completely.

Suspend:Pauses a table from a running replication. The database trigger will not be deleted from the source system. The recording of changes will continue, and related information is stored in the related logging tables in the source system.

Resume: Restarts the replication for a suspended table. The previous suspended replication will be resumed (no new initial load required).

Jobs: Not explored yet on this option.

From the above available options, we do not have such option to do only delta loading.

In this document we will see how to do delta loading only (means initial load not required). I stolen this concept from SLT expert Tobias Koebler.

When we load or replicate table from Data provisioning window, an entry will be placed in RS_ORDER table of SLT schema. For every few seconds the Monitoring job checks in the SAP HANA system whether there are any new tasks, and if so, triggers the master control job and then deletes the processed entries from the same table.

So if we can place an entry in RS_ORDER table (an INSERT statement with little cautious) related to delta loading then our task is fully done. First let us understand the structure of this table.

SID                - Source system ID

CI_HOST        - Hostname of Source System

TABLENAME  - Table name

ORDERID      - Data Provisioning Order ID (not yet used)

ACTION        - Requested Data Provisioning Action

Insert statement for RS_ORDER table would look like

INSERT INTO SCHEMA_NAME.RS_ORDER VALUES ('SID','CI_HOST','TABLENAME',ORDERID,'ACTION');

SAP ECC has been used as source. To see this in action, let us take T009 table as example.

Values for  SID and CI_HOST can be found in Data provisioning window. OrderID can always be set to zero(0) as this is not used.

Value for Action depends on what type of data provisioning you want to do.

Steps Involved in only Delta loading are:

1. Create an empty table with no data in it
2. Activate the Trigger and Logging information
3. Activate the Replication process

All the above steps are performed with the help of INSERT statements only

Step 1. Create an empty table with no data in it ==>  ACTION - T

ACTION parameter used will be "T" which creates an empty table. Insert statement would be:

INSERT INTO ECCDATA.RS_ORDER VALUES ('EH5','SAPEHP5_EH5_65','T009',0,'T');

Execute the above SQL in SQLConsole of HANA studio. Now you can see T009 table with Action as Create and Status as Executed.

We can confirm the table creation in SLT schema with no data in it. Also the entry which we created in RS_ORDER table will be deleted as it removes the processed entries.

Step2. Activate Triggers and Logging tables ==>  ACTION - M

ACTION parameter used will be "M" which activates the Trigger and logging information.

INSERT INTO ECCDATA.RS_ORDER VALUES ('EH5','SAPEHP5_EH5_65','T009',0,'M');

Now the Action will be changed to 'Record Only' and Status to 'In Process'. Entry in RS_ORDER table will be removed.

Step 3. Activate Delta recording ==>  ACTION - Q

ACTION parameter used will be "Q" which activates the Delta recording without doing an initial load.

INSERT INTO ECCDATA.RS_ORDER VALUES ('EH5','SAPEHP5_EH5_65','T009',0,'Q');

Now the Action will be changed to 'Replicate Only' and Status remains 'In Process'. Entry in RS_ORDER table will be removed.

From now any changes to table T009 in ECC will be captured in HANA. Now do the data preview on T009.

We see that there is no data. It means that there are no changes to table T009 yet, else you find delta records.

Now let us modify the source table in ECC. Changing ANZBP '00' to '1' for PERIV 'EM' as shown below.

Again do the Data preview for T009 in HANA studio. This time you definitely see the delta record

Though in Data Provisioning window we have few options, behind this window we can do little more than what data provisioning UI provides.

Disclaimer: This is only work-around and I never implemented this in the Production environment. Before you implement, you understand and test this thoroughly as neither SAP nor me would be responsible for any abnormal behavior.

Thank You for your time

There are some cool new monitoring features in SAP HANA SP7. You can right click the system and select:

- Open Memory Overview

- Open Resource Utilization

However, you may find you get the error: "Error while opening 'Memory Overview' Editor" or 'Resource Overview" - Reason: You do not have the required privilege.

This is because it requires a new role: sap.hana.admin.roles::Monitoring

If you add this role to your user, like this:

And now we can open up the new monitors!

These tools look like really useful ways of seeing how your HANA system is behaving in real-time, and should be particularly useful for development and testing environments.

Quite often, I have discussions with people on how HANA handles memory management. Robert Klopp and I got into this in some detail, so I thought I'd write a document giving the facts.

It is often thought that HANA is an in-memory database, only. However this is not accurate: SAP HANA persists all data to disk. Once it is persisted, upon startup, HANA (by default, this is configurable) loads data on request. It loads it based on the partition-column that is required. Let's take an example to understand this, because this is subtle.

Take the following table TRANSACTION. It has 7 columns including AMOUNT, TIMESTAMP and CUSTOMER_ID. It is partitioned by HASH(CUSTOMER_ID) and then RANGE(TIMESTAMP), by year. This is a total of 4x16=64 partitions, or 448 column-partitions.

At startup, HANA won't load table TRANSACTION and you can see the memory consumption is zero (well, 114kb). Just to be sure, I issue:

UNLOAD TRANSACTION;

Now, let's go ahead and check that in table SYS.M_CS_COLUMNS, which holds all the information about columns in-memory and out:

That's what we expect. So I'm going to go ahead and run a query which will definitely only hit a single partition-column. This should only load 2012 data for column TXAMOUNT.

Lets see what columns have now been loaded:

As expected, there are 8 columns - partitions 13 and 16, which are for the year 2012 and "Other", respectively. Now let's check how much data is used:

Let's run LOAD TRANSACTION ALL - to load all the table, to see how big it is:

Yes - asking this question only required 5% of the data to be loaded into memory. Note the column TXTIMESTAMP is a very big column - in many cases it would need much less than 5%.

What happens when HANA runs out of memory?

When HANA hits 95% memory, it starts to unload partition-columns that were least recently used. You can find them in the unloads trace file.

You can see that it unloads specific partition-columns (60,61 are the partition numbers, the column is at the end) based on those that were last used.

Final Words

I hope this helps clarify exactly how HANA behaves around loading data into memory. In many cases, it is possible to have more data than you have RAM in your HANA environment.

But, remember, the working set of partition-columns must take no more than around 50% of your overall RAM because HANA needs memory in which to do calculations. HANA is not designed to load and unload data continually and it is relatively inefficient at this compared to a row-based RDBMS - instead it is optimized for very fast performance in-memory. If you have a situation where your working set - the data on which you want to operate - is larger than your available memory, then performance will tank.

But, if you load data, schemas, tables, partitions and columns which you don't use into HANA, they don't need to be loaded into memory.

Hello Folks,

This document is to explain on how to apply currency translation in run time.

The below is the analytic view am using for which the currency translation has to be enabled:

This document is prepared based on HANA SPS6 revision 63.

Jody Hesch beautifully explained how to do Transpose and its use cases in the document (How To: Dynamic Transposition in HANA) which involves an additional table. If our requirement is to do table transpose without creating any additional table then we can do this completely by modeling in HANA studio. There could be many ways for doing and this is just another way of doing it.

Once the table is available in HANA studio, modeling will be done based on HANA base table and output of the Information view will be the transposed data.

DDL used for workaround is given below:
---------------------------------------------------------------------------------------------------
CREATE COLUMN TABLE TEST.ACTUALS (
     ID INTEGER NOT NULL,
     NAME VARCHAR (20) NOT NULL,
     YEAR VARCHAR (4),
     M_JAN INTEGER,
     M_FEB INTEGER,
     M_MAR INTEGER,
     M_APR INTEGER,
     M_MAY INTEGER,
     M_JUN INTEGER,
     PRIMARY KEY (ID));

INSERT INTO TEST.ACTUALS VALUES (1,'NAME1','2012',101,102,103,104,105,106);
INSERT INTO TEST.ACTUALS VALUES (2,'NAME2','2012',111,112,113,114,115,116);
INSERT INTO TEST.ACTUALS VALUES (3,'NAME3','2012',121,122,123,124,125,126);
INSERT INTO TEST.ACTUALS VALUES (4,'NAME4','2012',131,132,133,134,135,136);
INSERT INTO TEST.ACTUALS VALUES (5,'NAME5','2012',141,142,143,144,145,146);

INSERT INTO TEST.ACTUALS VALUES (6,'NAME6','2013',201,202,203,204,205,206);
INSERT INTO TEST.ACTUALS VALUES (7,'NAME7','2013',211,212,213,214,215,216);
INSERT INTO TEST.ACTUALS VALUES (8,'NAME8','2013',221,222,223,224,225,226);
INSERT INTO TEST.ACTUALS VALUES (9,'NAME9','2013',231,232,233,234,235,236);
INSERT INTO TEST.ACTUALS VALUES (10,'NAME10','2013',241,242,243,244,245,246);
---------------------------------------------------------------------------------------------------

The data in the table is:

Transposed data:

Implementation steps:

• Analytic view will be built on each base table column which needs transposition.
• In this case 6 columns need transposition, hence 6 Analytic views will be created.
• Calculated Column (VALUE) is created in each Analytic view which derives the value of a particular month in a year.
• Create Calculation View based on Analytic Views created above and join them together using Union with Constant Value.
• No need to create Calculated Column (MONTH) in each Analytic view as this can be derived in Calculation View to improve performance.

Now let us see this in action.

Let’s start with building Analytic view (AN_M_JAN) based on column M_JAN and in the Data foundation select the attributes ID, NAME, YEAR which will be common in all Analytic views andonly month M_JAN and skip other columns as shown below.

In the Logical Join, create Calculated Column (VALUE) and hard-code the value with the name same as base table column name (“M_JAN”) and validate the syntax as shown below.

In the Semantics, hide the attribute M_JAN as it is not required in the output as shown below.
 
Now Validate and Activate the Analytic view and do data preview. You will see only the values corresponding to M_JAN only.

Create second analytic view AN_M_FEB based on column M_FEB and the process will be the same as created above for M_JAN. In the data foundation make sure that you select month M_FEB not M_JAN.

Date preview for AN_M_FEB corresponds to M_FEB only.

Similarly create other 4 Analytic views AN_M_MAR, AN_M_APR, AN_M_MAY, AN_M_JUN.

Create Calculation View (CA_ACTUALS_MONTH). From the scenario panel, drag and drop the "Projection" node and add the Analytic view in it. Do not select M_JAN column as the Calculated column VALUE used instead. Similarly add the Projection node for other Analytic vies. Totally 6 Projection nodes are required for each Analytic view.

Now add the "Union" node above the six "Projection" node and join them. In details section click "Auto Map by Name". The only attribute missing in the output is "Month".  In Target(s) under Details section, click on create target as MONTH with datatype as VARCHAR and size as 3 which contains 3 letter month names (eg. JAN, FEb, MAR, etc.)

Right click on MONTH and choose "Manage Mappings" and enter the value for constant for Source model accordingly.

The final Calculation view would be like:

Save and Validate, Activate, and Do the data preview:

which is our desired output of the view with data transposed

But what about the performance?

Total number of records the information view contains:

To check if the filters are pushed down to the Analytic search, you need to find the “BWPopSearch” operation and check the details on the node in the visual plan. Please refer to awesome document by Ravindra Channe explaining "Projection Filter push down in Calculation View" which in turn points to the Great Lars Breddemann blog "Show me the timelines, baby!"

Let us apply filter for the year 2012.

SELECT NAME, YEAR, MONTH, VALUE FROM "_SYS_BIC"."MDM/CA_ACTUALS_VALUE" WHERE YEAR = '2012';

The Analytic search when expanded will show:

Though the table size is small in our case, Irrespective of table size, the filter is pushed down and fetching only the required records from the base table which helps in improving performance

Thank you for your time.
