  Error Message
  WRF_CONS305: Could not explode structured material &1
  
  &1 is a placeholder for the material number that could not be exploded.
  
  
  Cause
  This error occurs during the explosion of a structured material (i.e., a material with a Bill of Materials (BOM)) in processes such as production order creation, reservation, or goods issue. The system tries to explode the BOM to get the components but fails due to one or more of the following reasons:
  
  
  Missing or Incomplete BOM
  
  The BOM for the material does not exist, is incomplete, or is not valid for the plant or date in question.
  
  
  Invalid BOM Status
  
  The BOM might be flagged as deleted, inactive, or not released.
  
  
  Incorrect BOM Usage or Alternative BOM
  
  The BOM usage or alternative BOM number specified is incorrect or does not exist.
  
  
  Material Master Issues
  
  The material master data might be incomplete or inconsistent, especially in the MRP views or BOM-relevant fields.
  
  
  Authorization Issues
  
  The user or process might lack authorization to access the BOM or related data.
  
  
  System or Custom Code Issues
  
  Custom enhancements or user exits during BOM explosion might cause errors.
  
  
  
  Solution
  To resolve the error, follow these steps:
  
  
  Check BOM Existence and Validity  
  
  Use transaction CS03 (Display BOM) to verify that the BOM exists for the material and plant.  
  Check the validity dates and ensure the BOM is valid for the date of the explosion (e.g., order date).
  
  
  
  Check BOM Status  
  
  Ensure the BOM is not flagged as deleted or inactive.  
  Check the BOM header status and item status.
  
  
  
  Verify BOM Usage and Alternative BOM  
  
  Confirm that the correct BOM usage (e.g., production, costing) is assigned.  
  If alternative BOMs are used, verify their correctness.
  
  
  
  Check Material Master Data  
  
  Use MM03 to check the material master, especially MRP views and BOM-relevant fields.  
  Ensure the material is flagged as a structured material (i.e., it has a BOM).
  
  
  
  Check Authorizations  
  
  Verify that the user/process has the necessary authorizations to access BOM and material data.
  
  
  
  Review Custom Code or Enhancements  
  
  If custom user exits or BAdIs are implemented during BOM explosion, debug or review them for errors.
  
  
  
  Recreate or Correct BOM if Needed  
  
  If the BOM is corrupted or incomplete, recreate or correct it using CS01 or CS02.

  SAP Notes:  
  
  Check SAP Notes related to BOM explosion errors for your SAP version.  
  Example: SAP Note 123456 (hypothetical) might address BOM explosion issues.
  
  
  
  Debugging:  
  
  If the error persists, debugging the BOM explosion function modules (e.g., CS_BOM_EXPL_MAT_V2) can help identify the exact cause.
  
  
  
  
  Summary
  
  
  
  Aspect
  Details
