• What is the cause and solution for SAP error message LB141 - Proportion or product unit & is being used in bills of material ?

  The SAP error message LB141 indicates that a proportion or product unit is being used in bills of material (BOM) and cannot be deleted or modified. This error typically arises when you attempt to change or delete a material that is referenced in a BOM, and SAP is preventing this action to maintain data integrity.
  Cause:
  
  Material in Use: The material you are trying to delete or modify is currently being used in one or more BOMs.
  Proportion or Product Unit: The specific unit of measure (UoM) or proportion you are trying to change is linked to existing BOMs, which prevents modifications.
  Dependencies: There may be dependencies or links to production orders, purchase orders, or other documents that reference the material.
  
  Solution:
  
  
  Check BOM Usage: 
  
  Use transaction code CS03 (Display BOM) to check if the material is part of any BOMs. If it is, you will need to remove it from the BOM before making changes.
  
  
  
  Remove from BOM:
  
  If you need to delete or change the material, first navigate to the BOM using CS02 (Change BOM) and remove the material from the BOM.
  
  
  
  Check for Dependencies:
  
  Ensure that there are no other dependencies (like production orders or purchase orders) that are referencing the material. You can use transaction codes like CO03 (Display Production Order) or ME23N (Display Purchase Order) to check for any references.
  
  
  
  Change Unit of Measure:
  
  If you are trying to change the unit of measure, ensure that the new unit is not being used in any BOMs. You may need to update the BOMs to reflect the new unit of measure.
  
  
  
  Consult Documentation:
