• What is the cause and solution for SAP error message MU013 - Only 99 alternative BOMs are allowed ?

  The SAP error message MU013, which states "Only 99 alternative BOMs are allowed," typically occurs when you are trying to create or manage a Bill of Materials (BOM) in SAP and you exceed the limit of 99 alternative BOMs for a single material.
  Cause:
  In SAP, a material can have multiple alternative BOMs, which are used to define different configurations or versions of a product. However, the system imposes a limit of 99 alternative BOMs for each material. If you attempt to create or assign more than 99 alternative BOMs, you will encounter this error message.
  Solution:
  To resolve the MU013 error, you can consider the following options:
  
  
  Review Existing Alternative BOMs: Check the existing alternative BOMs for the material in question. You can do this by navigating to the BOM management transaction (e.g., CS03) and reviewing the list of alternative BOMs.
  
  
  Delete Unused Alternative BOMs: If there are alternative BOMs that are no longer needed, you can delete them to free up space for new ones. Be cautious when deleting BOMs to ensure that you do not remove any that are still in use.
  
  
  Consolidate BOMs: If possible, consider consolidating similar BOMs into fewer alternatives. This may involve combining components or configurations that are similar.
  
  
  Use Different Materials: If you have a legitimate need for more than 99 alternative BOMs, consider creating different materials for different configurations instead of relying on alternative BOMs.
  
  
  Consult SAP Documentation: Review SAP documentation or consult with your SAP support team for any specific configurations or enhancements that may allow for more than 99 alternative BOMs, although this is generally not standard practice.
  
  
  Related Information:
  
  BOM Management Transactions: Familiarize yourself with relevant transactions such as CS01 (Create BOM), CS02 (Change BOM), and CS03 (Display BOM) to manage your BOMs effectively.
  SAP Notes: Check for any SAP Notes related to BOM management that may provide additional insights or solutions.
  User Exits or Enhancements: In some cases, organizations may implement user exits or enhancements to modify standard SAP behavior. Consult with your technical team to explore this option if necessary.
  
  By following these steps, you should be able to address the MU013 error and manage your alternative BOMs effectively within the constraints of SAP.
