Hi Koen

This is just an example that I have used of course. We want to replenish items (stock) at branches that are in other branches. Think of this as updating stock. If there is no/little stock at a branch then request it from another branch. If a customer request a certain item, for instance, at a branch and the branch don't have it, we want to know if it is available somewhere else.

We track our stock for a certain period, thus the two dates.

Kind regards

Fred
