• What is the cause and solution for SAP error message FSGL_MIG006 - Inconsistency between BSEG_ADD and FAGLBSIS for document line &1 &2 &3 &4 ?

  The SAP error message FSGL_MIG006 indicates an inconsistency between the BSEG_ADD table and the FAGLBSIS table for a specific document line. This error typically arises during the migration of financial data, particularly when transitioning from classic General Ledger (G/L) accounting to the new G/L accounting in SAP S/4HANA or during data migration processes.
  Cause:
  The inconsistency can occur due to several reasons, including:
  
  Data Migration Issues: During the migration process, if the data from the old system is not correctly transferred or mapped to the new structure, inconsistencies can arise.
  Manual Adjustments: If manual adjustments were made to the financial documents after the initial migration, it could lead to discrepancies between the two tables.
  Configuration Errors: Incorrect configuration settings in the financial accounting module can also lead to inconsistencies.
  Missing or Incorrect Data: If certain entries in the BSEG_ADD table do not have corresponding entries in the FAGLBSIS table, or vice versa, this can trigger the error.
  
  Solution:
  To resolve the FSGL_MIG006 error, you can follow these steps:
  
  
  Analyze the Error Message: The error message provides specific document line information (e.g., document number, fiscal year, etc.). Use this information to identify the exact entries causing the inconsistency.
  
  
  Check Data Consistency:
  
  Use transaction codes like SE16 or SE11 to view the contents of the BSEG_ADD and FAGLBSIS tables.
  Compare the entries in both tables for the specified document line to identify discrepancies.
  
  
  
  Run Consistency Checks: 
  
  Use the SAP transaction code FBRA (Reset Document) or FBL3N (G/L Account Line Items) to check for inconsistencies and attempt to correct them.
  You may also use the transaction FAGL_MIG_CHECK to perform a consistency check for the migration.
  
  
  
  Correct the Data: Depending on the findings:
  
  If there are missing entries, you may need to manually create or adjust entries in the affected tables.
  If there are incorrect entries, you may need to delete or correct them.
