Partial Cleared Amount Does Not Appear When Specify Document Number in F-51

Hi experts:

I have documents which are partially cleared.

However, when I clear via F-04 and specify the original documents, the paid amount is not taken out and not appear on the screen as well. The total is the total amount of all original documents which is incorrect.

If I don't specify document number, and just process all open items, the partial paid amount does appear on the screen and taken out from total outstanding amount.

The document number of original document is set to BSEG-REBZG/REBZJ/REBZZ in partial payment line item.

In T-cd:FB00 I check "Include invoice reference" in Open items tab is active

Please let me know if I could specify document numbers to clear with the already paid amount?

Best regards,

Santiago
