5 day Forecast

Debit invoice

5 Day forecast UI

Double click the 999 will drill down the invoice

At here the amount is -999 but you can see forecast UI is 999.

Smart view report

Debit memo TEST54 and TEST155

Do the refund for Debit memo

Run the report and check smart view report

I understand refund like inflow but why the amount is (430)(300), in my opionion is positve amount 430 and 300 because them are refund.

SO i am confused why AP credit and debit memo have the wrong amount on forecast UI and report.
