Generally interest condition is set in the master data of security, FWZZ.
And the interest is posted after it’s due. But sometimes interest is paid partially before it’s due.
And I can think there are two options to do that.
Create a new condition type to reflect the partial interest paid.
For example, the interest should be paid on 31.12.2012, but there is partial
interest paid on 30.06.2012. So generally you can create a new condition in the master data for it.
And at the same time, to adjust the original interest condition which is due on
31.12.2012. But this needs to update all cash flow which use this
security, even different company codes. And sometimes it’s not practical.
Just post one manual posting via FWBS to reflect the partial interest.
And when posting the real interest in FWZE, change the amount to the interest left.
But it’s necessary to make the flow posting in FWBS relevant for accrual/deferral.
