I am learning SAP FI. For this I created a customer invoice using T.Code F-22 and later posted incoming payment from the customer using T.Code F-28. After that I checked the line items for this same customer using the T.Code FBLN5. The cleared items are still showing up in red. I double clicked on the DZ(Incoming payments) documents and also verified that the incoming payments went towards the correct DR (Customer invoice) document. could someone help me understand why this is happening?
