PGroup responsibility issue

Hi experts!

I am working with classic scenario SRM 5.5.

I have a PGroup referencing PGroup in R/3.

I have 2 type of products in SRM:

1) products replicated from R/3

2) products created locally (where Product ID in SRM = product ID in R/3).

I configured the responsibility tab for my PGroup as : 1) prodcat * / sourcesystem R/3;

2) prodcat * / sourcesystem SRM

I have no problem creating a SC and PO with items from R/3. However, when I select an item where log.system is SRM, there is no Pgroup populated for that item and I can’t create a shopping cart.

Please help.

Regards, Irina
