G/L account picked for the "wrong" source system entry

Question

Dear Experts,
in SRM 7.0, Classic Scenario, i am facing the following issue with respect to G/L account determination in the SC:
We have three R/3 systems connected to SRM. All these R/3 systems use the same Material Groups, but the G/L accounts are different in each R/3 system.
In the Table "Determination of G/L Account using product categories", i have maintained the repsective combinations. For each combination of product category and account assignment category, the respective G/L account is defaultet for the respective source system.
But in the shopping cart, the determination of the correct G/L does not always work. When a user enters the shopping cart initially with a line item that is accounted to his default account assignment category, than the correct G/L account for his source system is derived. But if he changes the account assignment category of the line item, than a G/L account from a "wrong" source system is getting picked up from the table.
I have checked the GUIDs of the product categories between "Comm_category" and "bbp_det_account" and they are correct.
What can be the reason for the picking of the G/L account from the wrong source system?
Can the note 1357871 bring the correction?
Thank you very much!

Hello Dima,
I think your problem comes from your source system for product category management.
Could you clarify one point: if you change account assignment category, does new G/L account have to be determined for same backend system too or not ?
If yes, correct new G/L account will be determined using your customizing (IMG: SAP Implementation Guide > SAP Supplier Relationship Management > SRM Server > Cross-Application Basic Settings > Account Assignment > Define G/L Account for Product Category and Account Assignment Category ).
If it does not work, log an OSS message.
If no, you need to switch value for each SC item field BBP_PDIGP-LOGSYS_FI from old backend source system to the new one. For this, use BBP_DOC_CHANGE_BADI.
Then, your customized G/L account definition for product category  and account assignment category should be OK.
