Tick the rows you do not want in this report and use Remove selected to take them out in one go — loading the AR file again brings them back. Status is a list you can add to, like Category and Purpose.
Load AR details from the toolbar to fill this from your sales ledger. Loan % is set per line and the repayment amount is calculated from the invoice value; type either one and the other follows. The percentage is what is stored, so correcting an invoice value keeps the line at the percentage it claims. Net receivable is the invoice less the repayment, and the summary and the charts use the NET.

Click the invoice count to open the documents behind a payee, then tick the ones to release — the total rolls up here and into the summary. The star approves the whole balance at once, and either figure can be typed over for a part payment. Only approved amounts are deducted from the projected closing balance, because nothing leaves the bank until somebody releases it. Anything marked ON HOLD is never ticked by “select all” — release it deliberately.
A category shown in red has not been classified yet. Set it once and this report will remember that payee next week — nothing in a general ledger records whether a payment is on a direct debit, so that fact has to come from you.
