• What is the cause and solution for SAP error message CM106 - You can only delete allocations of material components. ?

  The SAP error message CM106 ("You can only delete allocations of material components") typically occurs in the context of production planning and control, particularly when dealing with material components in a production order or a bill of materials (BOM). This error indicates that the system is preventing the deletion of allocations that are not allowed, usually because of the status of the production order or the nature of the components involved.
  Cause:
  
  Incorrect Status of Production Order: The production order may be in a status that does not allow for changes, such as "TECO" (Technically Completed) or "CLOSE".
  Component Type: The error may arise if you are trying to delete allocations for components that are not allowed to be deleted, such as non-stock items or components that are already reserved.
  Dependencies: There may be dependencies or links to other documents or processes that prevent the deletion of the allocation.
  Authorization Issues: The user may not have the necessary permissions to delete allocations.
  
  Solution:
  
  Check Production Order Status: Ensure that the production order is in a status that allows for changes. If it is in a completed or closed status, you may need to change it back to a status that allows modifications (if applicable).
  Review Component Type: Verify the type of material component you are trying to delete. If it is a non-deletable component, you may need to consider alternative actions, such as adjusting the BOM or production order.
  Check Dependencies: Look for any dependencies or links to other documents that may be preventing the deletion. Resolve any issues before attempting to delete the allocation again.
  User Authorization: Ensure that you have the necessary authorizations to perform the deletion. If not, contact your SAP administrator to obtain the required permissions.
  Use Transaction Codes: Utilize relevant transaction codes (like CO02 for changing production orders) to make the necessary adjustments.
