Production order enhancement for batches

Question

We have a scenario where the batch expiration date of the produced material in the Production order = to the earliest expiration date of one of the component batches. Once the batches of the component are allocated in the Production order, we want do a enhancement which calculates the expiration date for the produced material based on the earliest expiration date of the component batches.
This scenario is typical of a pharama industry I would think. Does anybody know if there is a BADI/user exit/function module I can use for this purpose.
thanks a lot

Answer 1

For this you need to have a Z program which calculates the Expiry date of the finished product based on the component materials expiry date.
There will be some specific or Key materials basing on which you calculate the Expiry date of the Finished product.
Maintian a Sort String to such materials like 'K'.
Now get a program developed in such a way that during the population of batch characteristics for finished product when process order release, it should check for these component materials expiry date and take the earliest expiry date and calculate basing on this.
There was a BADI released for this purpose, some time when I was working in my previous project. I will check and let you know.
Till then you can explore on the above said option.
Hope this helps you.
