How do I post interest in TBB1 without final payment amount

[anjireddy_appireddy]

Hi Team,

I would like to post interest invoice prior to due date using t.code-TBB1. The due dates are same for interest and Final payment (principal amount). There is no option to separate interest invoice and principal amount in TBB1. I wanted to post interest 2-3 days before and send the invoice to customer to make the interest amount payment.

Thank you,
