• What is the cause and solution for SAP error message CU403 - POS_TYPE (&1) in BOM of (&2) not defined ?

  The SAP error message CU403 indicates that there is a problem with the Bill of Materials (BOM) configuration in the system. Specifically, the error message states that the "POS_TYPE (&1) in BOM of (&2) not defined." This means that the system is unable to find a specific position type (POS_TYPE) for the BOM item identified by (&2).
  Cause:
  
  Missing Configuration: The position type specified in the BOM is not defined in the system. This could happen if the position type was never created or if it was deleted.
  Incorrect BOM Data: The BOM might have been incorrectly set up, leading to references to non-existent position types.
  Transport Issues: If the BOM was transported from another system, the necessary configuration for the position type may not have been included in the transport request.
  Custom Development: If there are custom developments or enhancements, they might be affecting the way position types are handled.
  
  Solution:
  
  
  Check Position Type Configuration:
  
  Go to the configuration settings for BOM (Transaction Code: CS01/CS02/CS03).
  Verify if the position type (&1) is defined in the system. You can check this in the configuration settings for BOMs (Transaction Code: OPL8).
  If it is not defined, you will need to create it.
  
  
  
  Create or Modify Position Type:
  
  If the position type is missing, create it using the appropriate configuration transaction.
  Ensure that all necessary attributes and settings for the position type are correctly defined.
  
  
  
  Review BOM Data:
  
  Check the BOM for the material (&2) to ensure that all entries are correct and that there are no references to undefined position types.
  If there are errors, correct the BOM data accordingly.
  
  
  
  Transport Requests:
  
  If the BOM was transported, ensure that all related configuration was included in the transport request.
