• What is the cause and solution for SAP error message CN877 - No operating time entered for the work center ?

  The SAP error message CN877 ("No operating time entered for the work center") typically occurs in the context of production planning and control when you are trying to create or modify a production order, and the system cannot find any operating time defined for the specified work center. This can prevent the system from calculating the necessary production times and scheduling.
  Cause:
  
  Missing Operating Time: The work center does not have any operating time defined in its configuration. Operating times are essential for the system to understand when the work center is available for production.
  Incorrect Work Center Assignment: The work center assigned to the operation in the routing may not be correctly set up or may not exist.
  Date Range Issues: The operating times may be defined, but they are not valid for the date range of the production order.
  Work Center Status: The work center may be set to inactive or may have been deleted.
  
  Solution:
  
  
  Check Work Center Configuration:
  
  Go to the transaction code CR02 (Change Work Center) or CR01 (Create Work Center).
  Enter the work center ID and check the "Basic Data" and "Capacity" tabs to ensure that operating times are defined.
  If no operating times are present, you will need to enter the appropriate operating times for the work center.
  
  
  
  Verify Date Ranges:
  
  Ensure that the operating times defined for the work center cover the dates relevant to your production order. If the production order is scheduled for a date outside the defined operating times, you will need to adjust the operating times accordingly.
  
  
  
  Check Work Center Assignment:
  
  Review the routing assigned to the production order to ensure that the correct work center is being used. You can do this by using transaction code CA03 (Display Routing) and checking the operations.
  
  
  
  Work Center Status:
  
  Ensure that the work center is active. If it has been marked as inactive, you will need to reactivate it.
  
  
  
  Consult Documentation:
  
  If you are unsure about how to configure the work center or operating times, refer to SAP documentation or consult with your SAP administrator or functional consultant.
