CDS Table function

Former Member — Wed, 24 Jan 2018 23:40:38 GMT

I am trying get familiar with ABAP CDS and stumbled with the following:

In ABAP CDS view with table function; we do the define the CDS view in HANA studio/ABAP ADT and leave the implementation to AMDP class in ABAP for native SQL. But we can write the same Native SQL with in the CDS; why do we need an AMDP implementing class/method here?

"ABAP CDS view with table function;"

There is not such a thing. There are either CDS views or CDS table functions.

"But we can write the same Native SQL with in the CDS"

No you can't do that in ABAP CDS.

"who do we need an AMDP implementing class/method here"

Because the language of CDS is a platform independent DDL.
