  The SAP error message WB2B602 indicates that the system could not find a Bill of Material (BOM) for a specified material and BOM alternative. This error typically occurs in the context of production planning, material requirements planning, or when trying to create a production order or a sales order that requires a BOM.
  Cause:
  
  Missing BOM: The most common cause is that there is no BOM created for the specified material (&1) and BOM alternative (&2).
  Incorrect BOM Alternative: The BOM alternative specified may not exist or may not be valid for the material.
  Plant-Specific BOM: The BOM may not be defined for the specific plant where the operation is being performed.
  Status of BOM: The BOM might be inactive or not released for use.
  Data Entry Error: There could be a typographical error in the material number or BOM alternative.
  
  Solution:
  
  
  Check BOM Existence:
  
  Use transaction code CS03 (Display BOM) to check if a BOM exists for the specified material and alternative.
  If it does not exist, you will need to create a BOM using transaction code CS01 (Create BOM).
  
  
  
  Verify BOM Alternative:
  
  Ensure that the BOM alternative you are trying to use is valid and exists for the material.
  If necessary, create or modify the BOM to include the correct alternative.
  
  
  
  Check Plant Assignment:
  
  Ensure that the BOM is assigned to the correct plant. You can check this in the BOM details.
  If the BOM is not assigned to the required plant, you may need to create a plant-specific BOM.
  
  
  
  Review BOM Status:
  
  Check if the BOM is active and released. If it is not, you may need to release it using transaction code CS02 (Change BOM).
  
  
  
  Correct Data Entry:
  
  Double-check the material number and BOM alternative for any typographical errors.
  
  
  
  Consult Documentation:
  
  If you are unsure about the BOM setup, consult your organization's documentation or reach out to your SAP support team for assistance.
