  Key Concepts: 
  Requirement date is a term used in SAP's Material Requirements Planning (MRP) component. It is the date by which a certain material or product must be available in order to meet customer demand. The requirement date is used to calculate the necessary lead time for production and procurement of the material or product. 
  
  How to use it: 
  In SAP, the requirement date is entered into the system when creating a material or product order. This date is then used to calculate the necessary lead time for production and procurement of the material or product. The system will then generate a schedule for production and procurement based on this requirement date. 
  
  Tips & Tricks: 
  It is important to ensure that the requirement date entered into the system is accurate, as this will affect the production and procurement schedule. It is also important to consider any external factors that may affect the availability of materials or products, such as supplier lead times, when setting a requirement date. 
  
  Related Information: 
  The requirement date is closely related to other terms used in SAP's MRP component, such as planned delivery time and planned independent requirements. It is also related to other components of SAP, such as Production Planning (PP) and Materials Management (MM).
