• What is the cause and solution for SAP error message C5618 - BOM alternative is used in a different master recipe ?

  The SAP error message C5618 indicates that a Bill of Materials (BOM) alternative is being used in a master recipe that is not compatible with the current configuration. This typically occurs when the BOM alternative specified in the master recipe is already assigned to another master recipe, leading to conflicts.
  Cause:
  
  BOM Alternative Assignment: The BOM alternative you are trying to use in your master recipe is already assigned to another master recipe. In SAP, each BOM alternative can only be linked to one master recipe at a time.
  Configuration Issues: There may be configuration settings that restrict the use of certain BOM alternatives in specific recipes.
  Data Integrity: There might be inconsistencies in the data, such as incorrect links between BOMs and recipes.
  
  Solution:
  
  Check BOM Assignments: Review the BOM alternatives assigned to the master recipes. You can do this by navigating to the BOM and checking its assignments in the relevant transaction (e.g., CS03 for displaying BOM).
  Change BOM Alternative: If the BOM alternative is indeed used in another master recipe, consider using a different BOM alternative that is not currently assigned to any other recipe.
  Reassign BOM: If you need to use the same BOM alternative, you may need to reassign it from the other master recipe, ensuring that it is no longer in use there.
  Review Master Recipe Configuration: Check the configuration settings for the master recipe to ensure that it allows the use of the desired BOM alternative.
  Consult Documentation: Refer to SAP documentation or help resources for specific instructions on managing BOM alternatives and master recipes.
