• What is the cause and solution for SAP error message CR146 - Shift finish & is after start of next shift & ?

  The SAP error message CR146 ("Shift finish is after start of next shift") typically occurs in the context of production planning and scheduling within SAP. This error indicates that there is a conflict in the scheduling of shifts, where the end time of one shift overlaps with the start time of the next shift. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Shift Overlap: The end time of the current shift is set to be later than the start time of the subsequent shift, which is not allowed in the scheduling configuration.
  Incorrect Shift Definitions: The shift definitions in the system may not be set up correctly, leading to overlaps.
  Data Entry Errors: Manual entry errors when defining shift timings can lead to this conflict.
  Configuration Issues: The configuration settings for work centers or production scheduling may not align with the defined shifts.
  
  Solutions:
  
  
  Review Shift Timings:
  
  Go to the shift definitions in the SAP system and check the start and end times for each shift.
  Ensure that the end time of one shift is not later than the start time of the next shift.
  
  
  
  Adjust Shift Definitions:
  
  If there is an overlap, adjust the timings of the shifts to ensure that they are sequential without any overlap.
  For example, if Shift A ends at 5 PM, ensure that Shift B starts at or after 5 PM.
  
  
  
  Check Work Center Settings:
  
  Review the work center settings to ensure that the shifts assigned to the work center do not conflict.
  Make necessary adjustments to the work center's shift schedule.
  
  
  
  Validate Production Orders:
  
  If the error occurs while processing a production order, check the order's scheduling and ensure that it aligns with the defined shifts.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on managing shifts and scheduling.
  
  
  
  Testing:
  
  After making adjustments, test the changes by attempting to create or modify a production order to ensure that the error no longer occurs.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like CR01 (Create Work Center), CR02 (Change Work Center), or CR03 (Display Work Center) to manage shift settings.
  Shift Planning: Understanding the shift planning process in SAP can help prevent such errors in the future.
  User Roles: Ensure that users have the appropriate roles and permissions to make changes to shift definitions and work center settings.
  
  By addressing the shift timing conflicts and ensuring proper configuration, you should be able to resolve the CR146 error in SAP.
