Hello Eric,
It seems updating SLED and getting expired batches into QI through deadline monitoring is the purpose.
Go to MCH1 table, generate a list for < Todays date in SLED.
You will get list of all expired materials.
Now create LSMW to delete SLED from batch master and also for updating SLED.
Delete all SLEDs using Lsmw and run QA07 for past dates, once you get all inspection lots created, run LSMW for updating SLEDs.
Amol.
