• What is the cause and solution for SAP error message FE079 - Scheduling not possible with a generic key ?

  The SAP error message FE079 "Scheduling not possible with a generic key" typically occurs in the context of scheduling operations in SAP, particularly when dealing with production orders, maintenance orders, or similar processes. This error indicates that the system is unable to schedule a task because it is trying to use a generic key that does not provide enough specific information for the scheduling process.
  Causes:
  
  Generic Key Usage: The error often arises when a generic key (like a range of values or a wildcard) is used in a scheduling context where a specific key is required.
  Missing Data: Required data for scheduling (like work center, capacity, or resource availability) may be missing or incorrectly configured.
  Configuration Issues: There may be issues with the configuration of the scheduling parameters in the system.
  Order Status: The order may be in a status that does not allow scheduling (e.g., if it is already completed or technically closed).
  Master Data Issues: Problems with master data (like incorrect or incomplete work center definitions) can also lead to this error.
  
  Solutions:
  
  Check the Key: Ensure that you are using a specific key rather than a generic one. If you are using a range or wildcard, try to specify a single value.
  Review Order Data: Check the production or maintenance order for completeness. Ensure that all required fields are filled out correctly.
  Verify Work Center: Make sure that the work center associated with the order is correctly defined and has the necessary capacity and availability.
  Check Configuration: Review the configuration settings for scheduling in the relevant modules (like Production Planning or Plant Maintenance) to ensure they are set up correctly.
  Order Status: Verify the status of the order. If it is not in a state that allows scheduling, you may need to change its status or create a new order.
