• What is the cause and solution for SAP error message VTBAPI202 - Required input field & for shipment must not be changed ?

  The SAP error message VTBAPI202 indicates that a required input field for a shipment must not be changed. This error typically occurs in the context of using the SAP Transportation Management (TM) or related modules when trying to modify shipment data that is not allowed to be changed after certain conditions have been met.
  Cause:
  
  Immutable Fields: Certain fields in a shipment are designed to be immutable after the shipment has been confirmed or processed. This is to maintain data integrity and ensure that the shipment's status is consistent.
  Business Rules: There may be specific business rules or configurations in your SAP system that prevent changes to certain fields once a shipment reaches a particular status (e.g., "In Transit," "Delivered").
  Incomplete Data: If required fields are missing or incorrectly filled, the system may throw this error when trying to save changes.
  
  Solution:
  
  Check Shipment Status: Verify the current status of the shipment. If the shipment is already in a status that does not allow changes, you will need to create a new shipment or reverse the current one if possible.
  Review Required Fields: Ensure that all required fields are correctly filled out before attempting to save changes. Check the configuration settings for the shipment to identify which fields are mandatory.
  Consult Documentation: Refer to SAP documentation or your organization's guidelines to understand which fields are immutable and under what conditions.
  Use Transaction Codes: If you are using transaction codes (like VT01N for creating shipments), ensure you are using the correct transaction for the intended operation (e.g., creating vs. changing).
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert who can provide insights based on your specific configuration and business processes.
