Post Individual line items from FPCJ to FI

Dear All

I could`t able to trace the functionality through which i can post the cash desk balance with individual line items to GL account.

In cash desk Functionality (FPCJ)

We receive many entries from the students, that store/accumulated in cash desk. After that we do transfer to the bank,through withdrawal from the cash desk. In that withdrawal the consolidated entries transfer to the bank account.

Then its become tough to do the bank reconciliation. If we could able to post entries in GL account with the individual instrument , it be easy to do the bank reconciliation.

So you are requested to guide me to update the customization to get the details  in balance withdrawal (FPG1).

Thanks

Mamatha
