Situation:
Sometimes you find blank value in field Sales Document in customer line item display in FBL5N.
Cause
Generally the field is not being filled, especially when you use field BSEG-VBEL2 (Sales Document) from T-code: OBCY for the relevant reference procedure in summarization.
However, the field BSEG-VBEL2 (Sales Document) is filled in the following processes:
1. Down payment requests
2. Make-to order
This is because system will transfer the sales order number when it is needed. For make-to order it is used to collect the cost, and for the down payment it is used to identify the paid down payments in FI.
Resolution
- Remove entry in T-code: OBCY;
- Use user-exit "EXIT_SAPLV60B_008"/"EXIT_SAPLV60B_004" to fill a value in VBEL2 in customer line item;
- Please check SAP note 301077 and SAP followings KBAs for more information.
