• What is the cause and solution for SAP error message STEP783 - Create MAT BOM: Alternative not defined ?

  The SAP error message "STEP783 Create MAT BOM: Alternative not defined" typically occurs when you are trying to create a Bill of Materials (BOM) for a material in SAP, but the system cannot find an alternative BOM defined for that material. This can happen in various scenarios, such as when you are working with configurable materials or when specific BOM alternatives are required for production.
  Cause:
  
  Missing Alternative BOM: The primary cause of this error is that the system is looking for an alternative BOM for the material you are trying to create or modify, but it does not exist in the system.
  Configuration Issues: If the material is a configurable material, the configuration settings may not be set up correctly, leading to the system not finding the appropriate BOM alternative.
  Incorrect BOM Type: The BOM type you are trying to create may not be compatible with the material or may not have been defined properly in the system.
  
  Solution:
  
  
  Check BOM Alternatives:
  
  Go to the BOM management transaction (e.g., CS01 for creating BOMs, CS02 for changing BOMs).
  Check if the alternative BOMs for the material are defined. If not, you will need to create the required alternative BOM.
  
  
  
  Create Alternative BOM:
  
  If the alternative BOM does not exist, create it using the appropriate BOM transaction (CS01).
  Ensure that you specify the correct BOM usage and alternative number.
  
  
  
  Review Material Configuration:
  
  If the material is configurable, check the configuration settings to ensure that the correct alternatives are defined.
  Use transaction CU50 to check the configuration profile and ensure that the necessary settings are in place.
  
  
  
  Check BOM Type:
  
  Verify that the BOM type you are using is appropriate for the material. You can check this in the BOM configuration settings.
  If necessary, create a new BOM with the correct type.
  
  
  
  Consult Documentation:
