IBP: planning considering shelf-life

Dear SAP IBP gurus,

we have a customer requesting to perform their planning in IBP keeping into consideration shelf-life. This requirement is quite common in the pharma, chemical and food & beverage industry, and I was wondering if any of you has already found himself with the challenge to implement such a requirement.

Making the requirement short: the customer wants to be able to identify when a certain stock will expire or will have a shelf-life lower than a certain threshold, as in this cases, the product could be not sellable (or sellable only in specific markets), bringing to a depreciation of its value. Products are produced and packed in batches in Production plants, moved to distribution centers and from there delivered to the customers.

Do you have any suggestion on how to implement the above requirement?

Many thanks for your support,

Vittorio Cotroni
