• What is the cause and solution for SAP error message CR160 - Shift sequence: Unnecessary entries are ignored ?

  The SAP error message CR160, which states "Shift sequence: Unnecessary entries are ignored," typically occurs in the context of shift planning or scheduling within the SAP system, particularly in modules like SAP PP (Production Planning) or SAP HCM (Human Capital Management). This message indicates that there are entries in the shift sequence that are not needed or are redundant, and as a result, they are being ignored by the system.
  Cause:
  
  Redundant Shift Entries: The shift sequence may contain multiple entries that are not necessary for the scheduling process. For example, if the same shift is defined multiple times or if there are overlapping shifts that do not contribute to the overall schedule.
  Incorrect Configuration: The configuration of shift sequences or work schedules may not be set up correctly, leading to unnecessary entries.
  Data Entry Errors: Manual data entry errors can lead to the creation of duplicate or unnecessary shift entries.
  
  Solution:
  
  Review Shift Sequences: Check the shift sequences defined in the system. Look for any duplicate or unnecessary entries and remove or consolidate them as needed.
  Adjust Configuration: If the issue is related to configuration, review the settings in the relevant customizing transactions (e.g., OOSB for shift planning) to ensure that the shift sequences are defined correctly.
  Data Cleanup: Perform a data cleanup to remove any redundant entries in the shift sequences. This may involve using transaction codes like CR01 (Create Work Center) or CR02 (Change Work Center) to manage shift sequences.
  Testing: After making changes, test the shift planning or scheduling process to ensure that the error message no longer appears and that the system behaves as expected.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CR01, CR02, CR03 (for work centers), and OOSB (for shift planning).
  Documentation: Refer to SAP Help documentation for detailed information on shift planning and configuration.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to shift sequences and provide patches or updates.
  User Forums: Engage with SAP community forums or user groups to see if others have encountered similar issues and what solutions they have implemented.
