• What is the cause and solution for SAP error message BOS01134 - Deletion of basic line &1 not possible: alternative lines are assigned ?

  The SAP error message BOS01134 indicates that you are trying to delete a basic line in a bill of materials (BOM) or a similar structure, but the deletion is not possible because there are alternative lines assigned to it. This typically occurs in scenarios where you have a BOM with alternative components or items, and the system prevents the deletion of a basic line that is still linked to these alternatives.
  Cause:
  
  Alternative Lines Assigned: The basic line you are trying to delete has alternative lines that are still active or assigned to it. SAP does not allow the deletion of a basic line if it is linked to other components that could affect the structure or integrity of the BOM.
  Data Integrity: SAP enforces data integrity rules to ensure that the relationships between components in a BOM are maintained. Deleting a basic line without addressing its alternatives could lead to inconsistencies.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Alternative Lines: Review the BOM or the relevant structure to identify the alternative lines that are assigned to the basic line you are trying to delete. You can do this by navigating to the BOM in the SAP GUI and checking the alternative components.
  
  
  Remove Alternatives: If you determine that the alternative lines are no longer needed, you can remove or deactivate them first. This may involve:
  
  Deleting the alternative lines.
  Changing the status of the alternative lines to inactive.
  
  
  
  Delete the Basic Line: Once the alternative lines are removed or deactivated, you should be able to delete the basic line without encountering the error.
  
  
  Consult Documentation: If you are unsure about the implications of removing alternative lines, consult your organization's documentation or speak with a functional consultant who specializes in BOMs.
  
  
  Use Transaction Codes: You can use transaction codes like CS02 (Change BOM) or CS03 (Display BOM) to manage the BOM and its components.
  
  
  Related Information:
  
  BOM Structure: Understanding the structure of BOMs and how alternative components work is crucial. Familiarize yourself with the concepts of alternative items and how they relate to the basic lines.
  SAP Notes: Check for any relevant SAP Notes that might provide additional insights or updates related to this error message.
  User Authorization: Ensure that you have the necessary authorizations to make changes to BOMs, as restrictions may also lead to errors.
  
  By following these steps, you should be able to resolve the BOS01134 error and successfully manage your BOM or related structures in SAP.
