S/4 HANA CDS View Search and related Fields Information

We used to spend lot of time in identifying the SAP delivered CDS view(s) or Existing CDS View(s) in the system before starting the development which is very important so that we don’t create duplicate objects and also we can utilize SAP delivered objects. Personally I felt the process was really painful and time taking.

As a Coding Savvy I could able to identify the tables which has all the Meta data information about the CDS view(s). So I had created a table function in S/4 HANA system which makes CDS search is easy. I am hoping that developers could able to leverage this code so that they could save lot of investigation time.

ABAP new Open SQL and CDS runtime

With the introduction of NW AS ABAP 740 SPS5, the New enhanced extended Open SQL was introduced. The new enhanced open sql has some good features such introduction of aggregate functions, right outer join, casting, etc making it a starting step for Code-Push down paradigm.

The Code push down techniques (CDS and New SQL) are compared in the demo here. Below is a demo program of data retrieval from BKPF and BSEG.

1) ABAP program using inner join between BKPF and BSEG
2) ABAP program using CDS view entity
3) ABAP program using enhanced Open SQL features
