Hi,
When you post payment in F-28, have you filled the Customer code and choosed which invoice open item do you want to clear or not?
If you don't do like this, the open items cannot be cleared, that's why they show red lines in report FBL5N.
In this case, there are 2 solutions:
- Reverse all payment document by tcode FB08 or F.80 (mass reverse). Then post payment again by tcode F-28 and choose which open item you want to clear.
- Clear customer by tcode F-32.
