0CO_OM_OPA_20 RSPAROBVAL/RSPOBART

Hallo Experts,

we ara using Business Content datasource 0CO_OM_OPA_20. Now we have the situation (in Test) that we have 3 cases

a) the fields RSPAROBVAL/RSPOBART are empty, so  therefore the corresponding fields e.g. 0PART_CCTR are empty.

b)  the fields RSPAROBVAL/RSPOBART are not empty, so  therefore the corresponding fields e.g. 0PART_CCTR are filled. That´s the best case.

c)  the fields RSPAROBVAL/RSPOBART are not empty, but the corresponding fields e.g. 0PART_CCTR are empty.

My problem ist, i don´t understand the way i can see why

1) the fields RSPAROBVAL/RSPOBART are empty

2) the corresponding fields e.g. 0PART_CCTR are emty even when the fields RSPAROBVAL/RSPOBART are not empty.

Can someone help me?

Thanks Santra
