• What is the cause and solution for SAP error message M_OBOM_WB_GNRL026 - There is already a sales order BOM for material &1 ?

  The SAP error message M_OBOM_WB_GNRL026 indicates that there is already a sales order Bill of Materials (BOM) for the specified material. This typically occurs when you attempt to create or modify a sales order BOM for a material that already has an existing BOM defined in the system.
  Cause:
  
  Existing Sales Order BOM: The primary cause of this error is that the material you are trying to create a BOM for already has a sales order BOM defined in the system.
  Incorrect Data Entry: There may be a mistake in the data entry, such as trying to create a BOM for a material that is not intended to have multiple BOMs.
  System Configuration: The system may be configured to prevent the creation of multiple sales order BOMs for the same material.
  
  Solution:
  
  
  Check Existing BOMs: 
  
  Use transaction code CS03 (Display BOM) to check if a sales order BOM already exists for the material in question. If it does, you can review its details.
  
  
  
  Modify Existing BOM: 
  
  If you need to make changes to the existing BOM, you can use transaction code CS02 (Change BOM) to modify the existing sales order BOM instead of creating a new one.
  
  
  
  Delete Existing BOM: 
  
  If the existing BOM is no longer needed, you can delete it using transaction code CS02. Be cautious with this approach, as it will remove the BOM from the system.
  
  
  
  Consult Documentation: 
  
  Review the SAP documentation or consult with your SAP administrator to understand the implications of modifying or deleting BOMs.
  
  
  
  Check User Permissions: 
  
  Ensure that you have the necessary permissions to create or modify BOMs in the system.
