• What is the cause and solution for SAP error message IUID045 - Embedded items are only allowed for IUID relevant main items ?

  The SAP error message IUID045: "Embedded items are only allowed for IUID relevant main items" typically occurs in the context of managing Item Unique Identification (IUID) in SAP, particularly when dealing with embedded items in a bill of materials (BOM) or similar structures.
  Cause:
  This error arises when you attempt to create or manage embedded items (sub-items) in a structure where the main item (parent item) is not marked as IUID relevant. In SAP, IUID is used for tracking and managing unique identifiers for items, especially in industries that require strict compliance with traceability and identification standards (like defense or aerospace).
  Solution:
  To resolve this error, you need to ensure that the main item (parent item) is set up correctly to be IUID relevant. Here are the steps you can take:
  
  
  Check Main Item Configuration:
  
  Go to the material master of the main item.
  Ensure that the IUID relevance is set correctly. This can usually be found in the "Basic Data" or "IUID" tab, depending on your SAP version.
  
  
  
  Set IUID Relevance:
  
  If the main item is not marked as IUID relevant, you will need to change its configuration. This typically involves:
  
  Navigating to the material master (transaction code MM02).
  Selecting the appropriate views (like Basic Data or IUID).
  Setting the IUID relevance flag.
  
  
  
  
  
  Review Embedded Items:
  
  Ensure that the embedded items are also configured correctly. They should be relevant to the main item and should not have any conflicting settings.
  
  
  
  Check BOM or Assembly Configuration:
  
  If you are working with a BOM, ensure that the BOM is correctly configured and that the main item is set as IUID relevant.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for specific details on IUID settings and requirements for your version of SAP.
  
  
  
  Testing:
  
  After making the necessary changes, try to perform the action again that previously resulted in the error to confirm that it has been resolved.
