• What is the cause and solution for SAP error message VSCE456 - BOM for &1 has a base quantity <> 1 ?

  The SAP error message VSCE456 indicates that there is an issue with the Bill of Materials (BOM) for a specific material (denoted by &1) where the base quantity is not equal to 1. This can occur in various scenarios, particularly when working with production orders, material requirements planning, or when trying to create or modify BOMs.
  Cause:
  
  Base Quantity Definition: The BOM is defined with a base quantity that is not equal to 1. This can lead to inconsistencies when the system expects a base quantity of 1 for certain operations.
  Configuration Issues: The configuration of the BOM or the material master may not align with the expected settings for the process you are trying to execute.
  Data Entry Errors: There may have been an error during the creation or modification of the BOM, leading to an incorrect base quantity.
  
  Solution:
  
  
  Check BOM Configuration:
  
  Go to the BOM transaction (e.g., CS03 to display BOM).
  Verify the base quantity of the BOM. If it is not 1, consider changing it to 1 if that aligns with your business process.
  If the BOM is intended to have a different base quantity, ensure that all related processes and configurations are set up to accommodate that.
  
  
  
  Adjust Material Master Settings:
  
  Check the material master data for the material in question. Ensure that the settings are consistent with the BOM requirements.
  If necessary, adjust the material master to reflect the correct base quantity.
  
  
  
  Review Production Order Settings:
  
  If this error occurs during the creation of a production order, check the order type and its configuration. Ensure that it is compatible with the BOM settings.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for specific guidance on BOM configurations and base quantities.
  
  
  
  Testing:
  
  After making changes, test the process again to ensure that the error is resolved.
  
  
  
  Related Information:
  
  BOM Types: Understand the different types of BOMs (e.g., single-level, multi-level) and how they relate to base quantities.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance.
  User Roles and Authorizations: Ensure that the user has the necessary authorizations to make changes to BOMs and material masters.
  Training: If this error is common in your organization, consider providing training for users on how to properly create and manage BOMs.
