Limit PO Err Combination of GR/IR control not allowed for external services

Question

Hi,
I am having a problem while replicating free text Limit PO's to R/3 in SRM 4.0 SP 13. The issue is while creating Free Text Limit SC with the  "Confirmation and Invoice" option checked in, the PO's get created in SRM but fails while replicating to R/3 and in RZ20 errors as "Combination of GR/IR control not allowed for external services" although in vendor master i don't have check for the field "GR-Based Invoice Verification".
On the contrary while creating SC with the "Invoice Only" the PO is successfully replicated to R/3 with item category as B for limit orders.
Now i have noticed if i make changes in the vendor master data i.e. check the flag "GR-Based Invoice Verification" then the PO in my first scenario gets replicated successfully and also with respect to the second scenario but it gets replicated in both the scenarios as item category "D".
As far as SRM standard it should have ideally behave like the below:
Limit SC with GR AND Invoice -> item category D
Limit SC with invoice only -> item category B.
Now my question is why do my PO's fail in R/3 in the first scenario and also if i check the flag in vendor master for GR-Based Invoice verification then in the second scenario the item category is "D" instead of "B".
Thanks in Advance.

Hi Georg,
We don't have any active implementation for the BADI BBP_PO_INBOUND_BADI.
