• What is the cause and solution for SAP error message FSH_PP_MD126 - You cannot change the component material in generic BOM ?

  The SAP error message FSH_PP_MD126, which states "You cannot change the component material in generic BOM," typically occurs when you are trying to modify a component material in a generic Bill of Materials (BOM). This is a common issue in SAP when dealing with generic BOMs, which are used to represent a group of similar products.
  Cause:
  
  Generic BOM Restrictions: In SAP, a generic BOM is designed to represent a family of products that share common components. The system restricts changes to the component materials to maintain the integrity of the generic structure.
  Material Type: The material you are trying to change may be linked to a specific material type that does not allow modifications in a generic BOM context.
  Status of the BOM: The BOM may be in a status that does not permit changes, such as being locked or in a released state.
  
  Solution:
  
  Use Specific BOM: If you need to change the component material, consider creating a specific BOM for the product variant instead of modifying the generic BOM.
  Check BOM Status: Ensure that the BOM is not locked or in a status that prevents changes. You may need to unlock or change the status before making modifications.
  Create a New Generic BOM: If the change is necessary and cannot be made to the existing BOM, you might need to create a new generic BOM with the desired component materials.
  Consult Documentation: Review SAP documentation or consult with your SAP administrator to understand the specific configurations and restrictions related to generic BOMs in your system.
  
  Related Information:
