Create PO from SC: error in transactin type

Question

Hi all,
I'm on SRM 5.0 with Extended classic scenario.
In particular the scenario is the follow:
create purchase requisition on R3 and replicate it as SC in SRM
create PO on SRM from SC and replicate it on R3
create good movements in R3.
The question is: when a SC is created on SRM, it is created with a values as backend doc type.
This value is takken from the OU (of the SC) for example ZB10.
But if i want to create a PO of type ZB11 from this SC, the system gives me an error: The SC has got another transaction type".
Type transaction type given to SC is taken from the BSA attribute of OU.
It's standard behaviour that I can create a PO from a SC only for a determinate transaction type?

Hi Enzo,
first:
The only chance to change the follow document type for PO within extended Scenario within BAdI is to change the BE_DOC_TYPE directly in the inbound BAdiI BBP_DOC_CHANGE_BADI (Method BBP_SC_CHANGE).
Here you can set the desired be_doc_type  which will be used for automatic sourcing.
Your problem seems to be an customizing error in your R/3 System:
Check your settings in SPRO (R/3)
--> Material Management --> Purchasing --> Purchase Order --> Define Document Types
Check Settings for your desired PO doc type
Your PO_DOC_TYPE must be available within the linkage to the doc_type used in your purchase requistion
For example:
I use 2 different PO_DOC_TYPES in SRM
Z1
Z2
Both types are set within OM (SRM) as an attribute (BSA and DP_PROC_TY )
Besides that, both PO_DOC_TYPES (z1 and Z2) are linked to my requistion doc type (z3) in R/3 customizing (mentioned above)
I can create Z1 and Z2 POs out of purchase requisitions with doc type z3 now.
Best regards
