Hi Priya,
For Posting loan repayment to Finance we need to do some configuration:
1. For every employee who takes a loan vendor account is created by the Finance and in that vendor account we need to update the employee number.
t.code fk03
2. For the loan repayment wagetype we assign a symbolic account.
3. Then in Activities in AC System, We will go to assign vendor accounts and in that we update our symbollic account with Account number as *0002 and the system will automatically read the Loan amount and Post it.
When you configure this while posting there will be an error of document split and you need to take the Account number from FI for the document split and update in technical assignment node
I hope this helps you. If this helps you in correct configuration then kindly flag helpful answer so that others can be benefited.
Thanks,
Bhabagrahi
