What is constraint in SAP PP-PMR - Predictive MRP?

SAP Term: constraint

• Component: PP-PMR

• Component Name: Predictive MRP

• Description: Constraints are defined for in-house materials, materials procured from suppliers, and materials that come from other plants stock transfer to restrict demand quantities per time period month or week. They are considered in pMRP simulations where a user can see if the defined constraint is violated. Material demands must not exceed a maximum constraint. Material demands must not fall below a minimum constraint.

• Key Concepts: 
  Constraint is a feature of the Predictive MRP (PP-PMR) component of SAP. It is used to define the conditions that must be met in order for a material requirement plan (MRP) to be considered valid. Constraints can be based on factors such as availability of resources, capacity, and lead times. 
  
  How to use it: 
  In order to use the constraint feature of PP-PMR, users must first define the constraints they wish to apply. This can be done by selecting the “Define Constraints” option from the PP-PMR menu. Once the constraints have been defined, they can be applied to an MRP by selecting the “Apply Constraints” option from the same menu. 
  
  Tips & Tricks: 
  When defining constraints, it is important to consider all relevant factors that may affect the validity of an MRP. This includes factors such as availability of resources, capacity, and lead times. Additionally, it is important to ensure that all constraints are properly applied to an MRP before it is executed.
