• What is the cause and solution for SAP error message CU402 - POS_NR (&1) in BOM of (&2) not defined ?

  The SAP error message CU402 indicates that there is a problem with the Bill of Materials (BOM) configuration in the system. Specifically, the error message states that a particular "POS_NR" (position number) in the BOM for a specified material is not defined. This typically means that the system is trying to reference a component or item in the BOM that does not exist or is not properly configured.
  Cause:
  
  Missing Component: The position number referenced in the BOM does not have a corresponding component defined.
  Incorrect BOM Configuration: The BOM may not have been created or maintained correctly, leading to missing or incorrect entries.
  Data Inconsistency: There may be inconsistencies in the data, such as changes made to the BOM that were not properly saved or updated.
  Authorization Issues: Sometimes, the user may not have the necessary permissions to view or edit the BOM, leading to this error.
  
  Solution:
  
  
  Check BOM Configuration:
  
  Go to the BOM transaction (e.g., CS03 to display BOM).
  Enter the material number and check the BOM for the specified position number.
  Ensure that all components are correctly defined and that the position number exists.
  
  
  
  Create or Update the Missing Component:
  
  If the component is missing, you may need to create it in the BOM using transaction CS01 (Create BOM) or CS02 (Change BOM).
  Ensure that the component is correctly defined with the necessary details.
  
  
  
  Check for Data Consistency:
  
  If there have been recent changes to the BOM, verify that all changes were saved correctly.
  You may also want to check for any transport requests that may not have been moved to the production environment.
  
  
  
  Review Authorizations:
  
  Ensure that the user has the necessary authorizations to access and modify the BOM.
  If there are authorization issues, contact your SAP security team to resolve them.
