HOWTO find S/4HANA Compatibility Views

[marcowahler]

Hi all,

recently I was asked: How to find out, if the "old R/3 Tables" are still used in S/4HANA!?

Within all the Simple Finance rework the universal journal should eliminate a lot of tables, so why they are still there an even have entries!?

Example: left side = HDB (zero entries), right side = Appl. Server (tousands of entries)



First of all, if you just look at the Table entries in S/4HANA this could be misleading.

Why is that? The answer are compatibility views! And  how can we find out what is happening behind the scene!?

Use t-code: SE16N (not SE16!)



doubleclick on Proxy Object: You can then find the DDL Source.



Now use the ABAP report to find out more details!

SE38: DEMO_SHOW_DDL_SOURCE -> FGL_FAGLFLEXA



again with DDL Source FGL_GLSI...



and again with DDL Source FGL_GLSI_ACD...



Finally you reach the "real table" called ACDOCA where the data is finally stored.



Hope that helps!
