Hi,
in any of your system other than production, I presume your interpretation algorithm i set to 15 which will pick up chq number entered in assignment field of the document.
Now try pass a payment entry in you outgoing GL with certain chq number. Then in FF67 , you post the same entry with an incorrect chq no in Bank R field. Save it and then run SM35, due this erroneous entry, you will find how the program will open FB05 (very similar to F-03) for you to correctly identify the open line item. Screen attached. Pls dont try to exit SM35 then, you need to complete the entire thing else it will create problem then.
Best regds
