• What is the cause and solution for SAP error message BAPI1080023 - Multiple BOMs do not permit assignments with the same material ?

  The SAP error message BAPI1080023 indicates that there is an issue with the assignment of materials in the Bill of Materials (BOM) when multiple BOMs exist for the same material. This error typically arises when you attempt to create or modify a BOM for a material that already has an existing BOM assigned to it, and the system does not allow for multiple BOMs with the same material in the same context.
  Cause:
  
  Multiple BOMs: The error occurs when there are multiple BOMs defined for the same material in the same plant or for the same usage.
  Incorrect Data Entry: The data being passed to the BAPI (Business Application Programming Interface) may contain duplicate entries or incorrect references to BOMs.
  Configuration Issues: There may be configuration settings in the system that restrict the assignment of multiple BOMs for the same material.
  
  Solution:
  
  Check Existing BOMs: Review the existing BOMs for the material in question. You can do this using transaction codes like CS03 (Display BOM) to see if there are already BOMs defined for that material.
  Modify or Delete Existing BOMs: If you find that there are existing BOMs that are no longer needed, you may consider deleting or modifying them to allow for the new BOM assignment.
  Use Different BOM Usage: If you need to maintain multiple BOMs for the same material, consider using different BOM usages. This allows you to have multiple BOMs for the same material under different contexts (e.g., production, engineering).
  Check BAPI Input Parameters: Ensure that the input parameters being passed to the BAPI are correct and do not contain duplicates or incorrect references.
  Consult Documentation: Review SAP documentation or help files related to BOM management and BAPI usage to ensure compliance with best practices.
  
  Related Information:
  
  BOM Usage: Understand the different usages of BOMs (e.g., production, engineering, sales) and how they can be utilized to manage multiple BOMs for the same material.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on BOM management.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), and CS03 (Display BOM) for managing BOMs effectively.
  BAPI Documentation: Review the documentation for the specific BAPI you are using to understand its parameters and constraints.
  
  By following these steps, you should be able to resolve the error and manage your BOMs effectively in SAP.
