I'm not sure I totally follow your issue. I believe you are saying you have many lots with a status of LTIN STIC SPCO STUP that are showing a red monitor light even though stock posting is done.
I believe this is becasue you have long term characteristics that have not been completed. Using long term characteristics means you can record these after your UD and stock posting is completed.
It doesn't mean you get a free pass to not record them!
If you want to clear these, you must go in the UD screen, (QA12) and manually mark the inspection complete.
Edit -->insepction completion-->Complete
After saving, the status will change to UD ICCO SPCO STUP
