SAP ABAP Central: ABAP CDS Consumption View Features Ultimate Test: Part 4

In first part, second part and third part of my blog I put ABAP CDS Consumption View to test and fulfilled some of most typical BW Query requirements. In fourth part of my blog I will challenge ABAP CDS Consumption View again. This time demonstrating percentage share calculation (similar to BW Query %CT function) and filtering key figures structure.

I created table function, table function implementation class, also created FACT, CUBE views and finally created CONSUMPTION view. I will not go much into details of implementation because all that you can explore on your own. What is more important is to understand ABAP CDS Consumption Views capabilities.

As you will see from screenshot below I calculate payment (dc) percentage share for year 1 and year 2 (last two columns).

SAP ABAP Tutorials and Materials, SAP ABAP Learning, SAP ABAP CDS, SAP ABAP Develoment

Percentage share is calculated dividing payment (dc) by payment (dc) total for respective year. There are two columns -payment (dc) total year 1 and payment (dc) total year 2 that are hidden by default and displayed on screenshot below
