Usage of MARC in DATABASE view after migration S4HANA.

[nh11]

Hi,

After ECC system got migrated to S4HANA and if there were custom database views exit on MARC before migration, so is it necessary to make some change to database view or it is fine as it is? Because in S4HANA MARC will be CDS view.

What is exactly a "custom database views exit"? (the word "exit" confuses me)

I think the OP meant " if there were custom database views on MARC before migration". The "exit" word should be more of "exists".

Hello nh1

The answer is "it really depends". It depends on what fields you expose in customs views based no MARC.S/4HANA indeed provides a replacement object (CDS view) NSDM_E_MARC for MARC. However the MARC table is still there and it's actively used. The NSDM_E_MARC view is based on MARC itself:

[...]
define view nsdm_e_marc<br>  as select from    marc             as t
[...]

Check out the definition of NSDM_E_MARC view. All the t.* fields are coming directly from the MARC table. So if your custom views use those fields only, you are ok.

Hi @sandra.rossi,

It is a mistake, I just used exit by mistake instead of exist.
