• Key Concepts: 
  Availability check is a feature of SAP Materials Management (MM) that helps to ensure that the right amount of materials are available for production or sales orders. It checks the current stock levels and compares them to the requested quantity to determine if the order can be fulfilled. The availability check also takes into account any planned receipts, such as purchase orders or production orders, to determine if the requested quantity can be fulfilled in the future. 
  
  How to use it: 
  The availability check is triggered when a sales order or production order is created. The system will check the current stock levels and any planned receipts to determine if the requested quantity can be fulfilled. If the requested quantity cannot be fulfilled, the system will display an error message and the order cannot be saved. 
  
  Tips & Tricks: 
  It is important to ensure that all planned receipts are entered into the system before creating a sales or production order. This will ensure that the availability check is accurate and that orders can be fulfilled without any delays.
