• What is the cause and solution for SAP error message CY823 - No capacity available at selected work center ?

  The SAP error message CY823: No capacity available at selected work center typically occurs when you are trying to schedule a production order or a process that requires capacity at a specific work center, but the system finds that there is no available capacity during the requested time frame. This can happen for various reasons, including:
  Causes:
  
  Capacity Overload: The work center is already fully booked with other production orders or activities, leading to no available capacity for the new order.
  Capacity Planning Settings: The capacity planning settings for the work center may not be configured correctly, leading to incorrect availability calculations.
  Incorrect Dates: The dates or times specified for the production order may fall outside the available capacity periods.
  Maintenance or Downtime: The work center may be scheduled for maintenance or downtime during the requested period.
  Resource Allocation: The resources (machines, labor) assigned to the work center may be allocated to other tasks, causing a lack of available capacity.
  
  Solutions:
  
  Check Work Center Load: Review the load on the work center to see if it is indeed overloaded. You can do this using transaction codes like CM01 (Capacity Overview) or CM21 (Capacity Planning).
  Adjust Scheduling: If the work center is overloaded, consider rescheduling the production order to a time when capacity is available.
  Modify Capacity Planning: Ensure that the capacity planning settings for the work center are correctly configured. This includes checking the available capacity, working hours, and any planned downtimes.
  Review Maintenance Plans: Check if there are any maintenance plans or downtimes scheduled for the work center that might be affecting capacity.
  Reallocate Resources: If possible, reallocate resources or adjust the production schedule to free up capacity at the work center.
  Use Alternative Work Centers: If the current work center is consistently overloaded, consider using alternative work centers that can handle the production requirements.
  
  Related Information:
