• What is the cause and solution for SAP error message 29645 - Material type & not supported for BOM headers with usage & ?

  The SAP error message 29645 indicates that the material type specified for a Bill of Materials (BOM) header is not supported for the specified usage. This typically occurs when you are trying to create or modify a BOM in SAP and the material type you are using does not align with the allowed configurations for BOMs in the system.
  Cause:
  
  Unsupported Material Type: The material type you are trying to use for the BOM header is not configured to be used with the specified BOM usage.
  BOM Usage Configuration: Each BOM usage (like production, engineering, etc.) has specific material types that are allowed. If the material type does not match the allowed types for that usage, this error will occur.
  Custom Configuration: If your organization has custom configurations or restrictions in place, it may further limit the material types that can be used for BOM headers.
  
  Solution:
  
  Check Material Type: Verify the material type you are using for the BOM header. Ensure that it is a valid type for the intended BOM usage.
  Review BOM Usage Settings: Go to the configuration settings in SAP (Transaction Code: SPRO) and check the allowed material types for the specific BOM usage you are working with. This can be found under:
  
  Logistics > Production > BOM > BOM Usage > Define BOM Usage.
  
  
  Change Material Type: If the material type is indeed unsupported, consider changing it to a valid type that is allowed for the BOM usage you are working with.
  Consult Documentation: Review SAP documentation or your organization's guidelines regarding BOM configurations to ensure compliance with the established rules.
  Contact SAP Support: If you are unsure about the configurations or if the issue persists, consider reaching out to your SAP support team or consulting SAP notes for further assistance.
  
  Related Information:
  
  BOM Usage: BOMs can have different usages such as production, engineering, sales, etc. Each usage may have different requirements and allowed material types.
  Material Types: Common material types in SAP include raw materials, finished goods, semi-finished goods, etc. Each type has specific characteristics and uses.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  CS01: Create BOM
  CS02: Change BOM
  CS03: Display BOM
  SPRO: Access configuration settings.
  
  
  
  By following these steps, you should be able to resolve the error and successfully create or modify the BOM as needed.
