FPCJ Cash Payment - Balance in Document currency is not zero, posting not possible

Hi Experts,

Appreciate if you could provide solution...

I am getting error message "Balance in Document currency is not zero, posting not possible"

Message no. >0003 while using FPCJ for "CASH" payment.

However if I use only check payment or Cash and Check(both) then system will post entry successfully.

Thanks in advance.
