  The SAP error message CR122, which states "An available capacity has already been maintained," typically occurs in the context of capacity planning and management within the SAP system, particularly in the Production Planning (PP) module. This error indicates that there is an attempt to create or modify a capacity planning record (such as a work center or production resource) that already has an existing entry for the specified time period.
  Cause:
  
  Duplicate Entry: The most common cause of this error is that there is already an existing capacity record for the same work center and time period that you are trying to maintain.

  Check Existing Records: 
  
  Navigate to the relevant transaction (e.g., CR02 for changing work center capacities) and check if there is already a capacity record for the same work center and time period.
  If a record exists, you may need to modify or delete it instead of trying to create a new one.
  
  
  
  Adjust Time Periods: 
  
  If you need to maintain a new capacity record, ensure that the time period you are trying to enter does not overlap with existing records. Adjust the time periods accordingly.
  
  
  
  Review Configuration: 
  
  Check the configuration settings for capacity planning in your SAP system. Ensure that there are no conflicting settings that could lead to this error.
