• What is the cause and solution for SAP error message FINS_CFIN_AC_CFG020 - Mapping action for G/L accounts already defined; data not saved. ?

  The SAP error message FINS_CFIN_AC_CFG020 indicates that there is an issue with the mapping of General Ledger (G/L) accounts in the Central Finance (CFIN) configuration. Specifically, it means that a mapping action for the G/L accounts you are trying to define has already been established, and as a result, the system is preventing you from saving the new mapping.
  Cause:
  
  Duplicate Mapping: The most common cause of this error is that the G/L account mapping you are trying to create already exists in the system. This can happen if the mapping was previously defined and not deleted or if there was an attempt to create a mapping for the same account again.
  Configuration Issues: There may be inconsistencies or errors in the configuration settings related to Central Finance, particularly in the mapping of accounts.
  Data Integrity: The system is designed to maintain data integrity, and it will not allow duplicate entries for G/L account mappings.
  
  Solution:
  
  
  Check Existing Mappings: 
  
  Navigate to the relevant configuration area in SAP where G/L account mappings are defined (usually under Central Finance settings).
  Review the existing mappings to see if the G/L account you are trying to map is already listed. If it is, you may need to modify or delete the existing mapping instead of creating a new one.
  
  
  
  Modify Existing Mapping:
  
  If you find that the mapping already exists and needs to be updated, you can modify the existing entry instead of creating a new one.
