• What is the cause and solution for SAP error message CM119 - Allocation to the alternative sequence already exists. ?

  The SAP error message CM119, "Allocation to the alternative sequence already exists," typically occurs in the context of production planning and control, particularly when dealing with alternative sequences in routing or production orders. This error indicates that there is an attempt to allocate resources or materials to a production order that already has an allocation for the specified alternative sequence.
  Cause:
  
  
  Duplicate Allocation: The primary cause of this error is that the system has detected an existing allocation for the same alternative sequence. This can happen if:
  
  You are trying to allocate resources to a production order that has already been allocated.
  There is an attempt to create a new allocation for an alternative sequence that is already in use.
  
  
  
  Configuration Issues: Sometimes, the configuration of the routing or production order may not allow for multiple allocations to the same alternative sequence.
  
  
  Data Integrity Issues: There may be inconsistencies in the data, such as incorrect entries in the master data or production order.
  
  
  Solution:
  
  
  Check Existing Allocations: Review the production order or routing to see if there is already an allocation for the alternative sequence you are trying to use. You can do this by:
  
  Navigating to the production order and checking the allocations.
  Using transaction codes like CO03 (Display Production Order) to view the details.
  
  
  
  Modify or Remove Existing Allocations: If you find that there is an existing allocation that is causing the conflict, you may need to:
  
  Modify the existing allocation if it is incorrect.
  Remove the existing allocation if it is no longer needed.
  
  
  
  Use a Different Alternative Sequence: If the allocation is necessary and cannot be removed, consider using a different alternative sequence that does not have existing allocations.
  
  
  Check Configuration: If the issue persists, review the configuration settings related to alternative sequences in your routing or production order setup. Ensure that the settings allow for the desired allocations.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling alternative sequences and allocations.
  
  
  Contact SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance, especially if you suspect a bug or data integrity issue.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CO01 (Create Production Order), CO02 (Change Production Order), and CO03 (Display Production Order).
  Master Data: Ensure that your master data (materials, routings, work centers) is correctly set up and does not contain any inconsistencies.
  User Authorization: Ensure that you have the necessary authorizations to make changes to production orders and allocations.
  
  By following these steps, you should be able to identify the cause of the CM119 error and implement a suitable solution.
