• Key Concepts: 
  Availability check is a feature of SAP's Material Requirements Planning (MRP) component that helps to ensure that the right amount of materials are available for production. It checks the current stock levels and compares them to the planned requirements for production. If there is not enough material available, it will alert the user and suggest alternative solutions. 
  
  How to use it: 
  The availability check can be used in two ways: manually or automatically. To use it manually, the user can enter the planned requirements into the system and then check the current stock levels to see if there is enough material available. If there is not enough material, the user can then take action to acquire more or adjust the production plan accordingly. To use it automatically, the user can set up an availability check rule in the system which will automatically check the stock levels and alert the user if there is not enough material available. 
  
  Tips & Tricks: 
  When setting up an availability check rule, it is important to consider how often it should be run. If it is run too often, it may cause unnecessary delays in production due to false alarms. On the other hand, if it is run too infrequently, it may not detect shortages in time for corrective action to be taken. 
  
  Related Information: 
  The availability check feature of SAP's MRP component is closely related to other features such as inventory management and demand planning. These features work together to ensure that materials are available when needed and that production plans are accurate and up-to-date.
