Question:

Explain the details concerning the control of expiry date for incoming raw materials and also for the finished goods. How is the expiry of the raw material or a finished good controlled and monitored in SAP QM? What are the transaction codes involved? Does MM01 T-code have any relevance for expiry date? How will the system respond if a material got expired?
 
Ans:
 
Follows these steps:
 
1) MM02 you have to maintain the min shelf life and maximum shelf life. 
2) This makes manufacturing date should be entered mandatorily in the MIGO
3) System also clearly the screens material with min shelf life lesser than what is maintained.
4) Once GR is done for batch managed the shelf life is updated in the batch. MSC2N
5) Otherwise at any point of time you can check the remaining shelf life using MB5M
6) Once the material reaches near to the shelf life, you can either schedule a program QA05, QA07 which will move the expired material to block, and if batch managed it will make the batch to restricted.
7) If you are using recurring inspection expiry period has more relevance.
 
Notes:
 
For re-validation of material based on self life expiry date, activate 09 inspection type in material master, so based on inspection interval/ self life expiry date system will post stock again in QI & create inspection lot with ref to type "09".
 
There is no direct connection between the expiry date and the Re-validation inspection date.
 
Expiry Date:
 
There is a field called "Total shelf life" in the Plant Data \ Stro1 View of material master. That decides the Shelf life Expiry date for the Batch of the material.  Now, for Incoming material the shelf life get calculated from the Value we feed in the Mfg Date in GR (MIGO).  e.g. If there is 36 MON is maintained in the "Total shelf life" in Plant Data \ Stro1 view of material master and at the other hand we enter the mfg date in the GR (MIGO) as 30.01.2099 then system will add 36 MON in this date, calculate the Shelf life as 29.07.2099 and post it to the Batch. At the same moment the batch is triggered with Posting MIGO document.  Now this same date will go to the field "Shelf Life Exp. Date 1" of the batch (MSC3N).  The same thing happens to the Finished product also it, here the mfg date is supposed to be entered at GR or Auto GR against the Order.
 
When the material reaches its shelf life you can run QA05 or you can schedule it through QA07. If the material is not batch managed the material is moved to blocked otherwise the batch is restricted. Once moved to block you can move the material back to quality activating 08 inspection. Lot will be created and then you can do the revalidation of the shelf life material and then you can move the stock to either unrestricted if the testing seems ok or otherwise scrap.
