  The SAP error message FRE456 indicates that there is an issue with the initial transmission of a subtree in the context of a data transfer process, typically related to the SAP Application Interface Framework (AIF) or similar data management processes. The message suggests that the initial transmission of a subtree from a specified source (indicated by '&1') is only allowed if a complete transmission has been successfully completed beforehand.
  Cause:
  
  Incomplete Previous Transmission: The error usually occurs when there was an attempt to initiate a new transmission (initial transmission of a subtree) without having completed the previous transmission successfully.

  Solution:
  
  Check Previous Transmissions: Verify if the previous transmission was completed successfully. You may need to check logs or transaction records to confirm this.
  Complete Pending Transmissions: If there are any pending or incomplete transmissions, ensure they are completed before attempting to initiate a new subtree transmission.

  Data Validation: Validate the data being transmitted to ensure it meets the required structure and integrity constraints.
  Consult Documentation: Refer to SAP documentation or notes related to the specific module or process you are working with for any additional troubleshooting steps or known issues.
