Material Master issues . Pls help

[undorejected]

Hello everyone,

I have some issue with the material master. my company has over 50 facilities all over the world and they all use SAP. now when you receive products from one of the 50 locations some of these product has an expiration date of 1 year but when we we receive the product, the expiration date is no longer one year. The moment we receive the product the expiration date becomes one month. So we need to use that product in production within one month before it expires. in SAP the expiration date is as I said one year, but when its in our warehouse that one year becomes only one month for storage restrictions. now is there any way I can make SAP track the expiration date for the product from when its received and use it in production before it expires after one month. I tried changing the expiration date in the material master but that changed the expiration date in all locations which was going to cause a huge problem for all the other facilities as they have the expiration date for the product as one year.

Thanks for the help in advance
