DDIC differences between two systems.

[former_member848910]

I need to find the DDIC differences for a system before and after its upgrade to HANA. What is the procedure to find the differences in detail?

We compared (for example) the first S/4HANA sandbox system with the ECC development system using "custom code remote compare". For example we checked VBAK, VBAP, VBEP.

But: The number of standard ddic objects is huge...

Some differences "need to be known" like acodca, prcd_elements, matdoc, matdoc_extract... as it's "replacements". Vbup is not existing any more, as well as (many) other tables. Value/Amount-fields are extended (in general).

I don't know any tool, which will give you all differences.

The most optimal way to check differences to be considered is using the custom code migration app (BTP, S/4HANA onprem Sandbox or ATC).
