Hi Gary,
The material best before date has expired and either the material can be scraped using the movement type - 551 or issued to the cost center by 201.
The stock has to be either scrapped or issued to the cost center, management has to taken a decision on it. based on that we can issue to cost center or scrap it.
Also you can schedule a background job to block the material in quality, 1-2 days before by using the tcode - QA07 (Manual trigger) , QA05 - Job Planning.
Thanks,
Vamsi
