Hi Pranav,
To achieve this requirement, I think these are the possible options:
Option 1) Create the bonus payable as Vendor instead of GL Account and link this vendor to Recon account ( Create a separate vendor account group if required, to distinguish from regular vendors)
Option 2) you can see the GL account balances in FBL3N/FS10N by giving range of GL Accounts from 100500 to 100503 , without using recon account concept here.( AS there is no sub-ledger concept for GL )
