• What is the cause and solution for SAP error message M7423 - Subcontracting component & requires serial number ?

  The SAP error message M7423, which states "Subcontracting component & requires serial number," typically occurs in the context of subcontracting processes where a component that is being sent to a subcontractor requires serial number tracking. This error indicates that the system expects a serial number for the component being processed, but it has not been provided.
  Cause:
  
  Serial Number Requirement: The component in question is configured in the system to require serial number tracking. This is common for items that are high-value, sensitive, or require traceability.
  Missing Serial Number: When creating a purchase order or a production order for subcontracting, the system checks if the component requires a serial number. If the serial number is not provided, the error will be triggered.
  Configuration Settings: The material master record for the component may be set to require serial numbers, but the necessary data is not being entered during the transaction.
  
  Solution:
  
  Enter Serial Number: When processing the subcontracting order, ensure that you enter the required serial number for the component. This can typically be done in the relevant transaction screen where you are creating or processing the order.
  Check Material Master: Review the material master record for the component to confirm that it is set up correctly. You can do this by navigating to the material master (transaction code MM03) and checking the "General Plant Data/Storage" and "Sales: General/Plant" views to see if the serial number requirement is correctly configured.
  Adjust Configuration: If the serial number requirement is not needed for the component, you may need to adjust the configuration in the material master to remove the serial number requirement. This should be done with caution and typically requires authorization.
  Training and Documentation: Ensure that users involved in the subcontracting process are trained on the importance of entering serial numbers and understand how to do so correctly.
