• What is the cause and solution for SAP error message FML_MIGRATION003 - Execute report in initial migration mode first, before delta mode for & ?

  The SAP error message FML_MIGRATION003 indicates that you are trying to execute a migration process in delta mode without first completing the initial migration. This error typically occurs in the context of financial data migration, particularly when using the Financial Migration Tool (FMT) in SAP S/4HANA.
  Cause:
  The error arises because the migration process is designed to be executed in two phases:
  
  Initial Migration Mode: This is the first phase where the bulk of the data is migrated from the legacy system to the SAP system. It involves transferring all necessary data to establish a baseline.
  Delta Mode: This phase is intended for capturing any changes that occurred in the legacy system after the initial migration. It is meant to synchronize the data between the legacy system and the SAP system.
  
  If you attempt to run the delta migration process without having completed the initial migration, the system will throw this error.
  Solution:
  To resolve this error, follow these steps:
  
  
  Execute Initial Migration:
  
  Ensure that you have completed the initial migration process successfully. This involves running the relevant migration reports and ensuring that all necessary data has been transferred to the SAP system.
  
  
  
  Check Migration Status:
  
  After completing the initial migration, check the status of the migration to confirm that it was successful. You can do this by reviewing the logs and ensuring there are no errors.
  
  
  
  Run Delta Migration:
  
  Once the initial migration is confirmed to be successful, you can proceed to execute the delta migration process. This will allow you to capture any changes that occurred in the legacy system after the initial migration.
  
  
  
  Review Documentation:
  
  Refer to the official SAP documentation for the Financial Migration Tool for detailed steps and best practices regarding the migration process.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as Fiori Apps, LTMC (Legacy Transfer Migration Cockpit), or specific migration reports related to financial data.
  Migration Cockpit: If you are using the SAP S/4HANA Migration Cockpit, ensure that you are following the correct procedures for data migration.
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or updates related to the migration process.
  Support: If you continue to experience issues, consider reaching out to SAP support or consulting with an SAP expert who specializes in data migration.
