F.13 clearing with open Spl GL item to normal open item

Hi Team,

We are facing unable to clear the open items using F.13 for one of the Spl GL (Down payment) with the other normal open items based on the Assignment field which has been already maintained in OB74.

Please find the below screenshot.

1. Vendor line item (open items) report with Assignment subtotal: It is Zero.

2. F.13 test run execution: It is not combining all these 4 items to clear. (3 normal and 1 Spl GL)

The highlighted 4 documents we are trying to clear through F.13 but unable to do so. Please let us know if we are missing anything.

3. OB74 set up

Thank you,

AJ.
