What is a planned independent requirement?
Independent requirements and dependent requirements are the two main types of requirements you encounter when configuring SAP planning. This is what they are:
MRP vendor selection
It is possible to let MRP propose the preferred (or fixed) vendor for your external procurement. This is especially useful in a scenario where a central purchasing department is dictating vendor selection, but where the actual procurement decisions (quantity and timing) is done elsewhere (e.g. production dept for procurement of raw materials). This post will [...]
Lot-size for continuous production and process industry
A suitable lot-size for continuous production can be hard to come up with. Picture the situation of a mineral oils manufacturer that refines crude oil to 3 co-products. The planner wishes to control the process flow to align the production with demand (i.e. the refinery is not continuously refining at the same speed as it [...]

Firming types in MRP
In a production environment it may not be preferable that new requirements on the short term can influence production quantities. The length of the term can be determined by the planning time fence. How MRP treats new requirements in this period can be determined using the firming type in customizing for MRP type:
ATP on semi-finished materials
Today we learned from SAP Support that it is not possible to distribute dependent requirements through time for Available to Promise. What does that mean? Well in our case (process industry) it means the following: We have a material B1 that is made from A1. We sell both items A1 and B1. Since this is [...]
