In the Shop Order, Exact Online for Manufacturing checks if the materials, needed for the order, are available. If the materials are not available Exact gives a clear warning.
The material requirement are matched against the available stock (‘in stock’). However when other shop orders request the same material or when the same material was listed twice in the shop order, than this may lead to wrong conclusion, that you have enough stock to start production.
In the new situation the material requirement is also matched against the ‘projected stock’. As a result you get better insight in the available stock of the materials needed to manufacture the product.
