How to set Expiry date for a particular Batch in SAP?

The Issue

For one particular batch, in SAP the expiry date is different from the expiry date maintained in BOX. Now how to change the expiry date, could some one please tell me the Tcode in which I can set the expiry date.

The Solution

As you can see from the previous post, to edit the Expiry Date, do it in MSC2N.
Now to explain a little further, Standard SAP gets the Expiry date by using the following Formula:
Production Date + Total Shelf life days in Material Master (Plant Data Stor. 1 view).
So maybe you can look into this to prevent future errors in Expiry Date.
