  Configuration Issues: Incorrect configuration settings in the new G/L can also lead to mismatches between the two tables.
  
  Solution:
  
  Data Consistency Check: Use transaction codes like FB03 to display the document in BSEG and FAGLBALN to check the balances in FAGLBSAS. This will help identify the specific inconsistencies.
  Reconcile Data: Perform a reconciliation of the data between BSEG and FAGLBSAS. This may involve running reports or using tools provided by SAP to identify discrepancies.
  Adjust Documents: If discrepancies are found, you may need to adjust the documents manually. This could involve reversing and re-posting transactions or making necessary corrections in the respective tables.
