Background:

This is an alternative approach to Column to Row transpose discussed in Modelling: Column to Row Transpose using Matrix in HANA. In this article we'll use multiple projection steps in a calculation view to transpose from column to row.

Problem Statement:

The following is output of Analytic View (AN_DATA)

We'd like to transform the dataset (from column to row) as shown below

Solution Option:

1. Build the calculation view as below. Insert one Project Node for each column (3 projections for "AGR", "OIL" and "TAX").

2. Rename the Column "AMOUNT_OIL" to "AMOUNT" in Projection_OIL (highlighted in yellow in the above picture). Similarly rename 'AMOUNT_AGR" and "AMOUNT_TAX" in the other two projections

3. In the Union node, create a new target "AMT_TYPE" and map as below.

4. Expose the DOCID, COUNTRY, AMT_TYPE and AMOUNT in the Aggregation node and activate the calculation view.

Result:

Now execute the following Query for the desired output
