Hi all,

could someone explain me how the relationship between customer master partner and check table is created?

I.e. partner function AG at KNVP. The check table is KNA1 and KUNNR.

The partner function itslef is maintained a table TPAR with relationship to TVPA by partner type KU.

At table TVPA I can find check table KNA1.

But how does the system know that KUNNR has to be checked?

Or in case of other check tables (partner types) i.e. PERNR or PARNR...

And on the other way:

How is the relationship build up that for KU and KNA1 the check is based on KUNN2?

There are also some own partner types (Z...). By data I can see that the check is based on PERNR. But I do not understand how it is mapped / build up / implement in the system.

Can some explain?

Regards

Christian
