SAP Business ByDesign
Reproducing the Issue
- Go to Purchase Requests and Orders
- Select view Purchase Orders
- Select the respective third party order which has kit items
- Navigate to document flow
- There is a process communication error in the purchase order
- Now go to Application and User management
- Select view Business data Consistency: Process Communication Errors
- You can see the main error is "PO Kit Item ID not found in acknowledgment".
This error occurs because of an inconsistency between the Kit sub-items of the Purchase Order and second/follow up Sales Order. The reason is because the kit item list is changed after the creation of PO but before the creation of follow up Sales Order (SO).
So, after creation of PO, user changed the kit item list for sales kit header e.g. you removed an item and added a new item in the kit.
We only process the sales kit header items from the message sent from PO. Then to create the sales order, we read the contents of the sales kit list from inventory processing to get these details. This means that if there is a change to the kit master data, the new kit list is added to the SO and not what is maintained on the PO.
You have to cancel the affected Sales Order and related documents, restore the Kit definition back to the contents included in the purchase order, and then re-create the Sales Order again, keeping the Kit master data consistent in the meantime.
Please keep the master data consistent while completing these type of third party processes to avoid this issue.
