Select Matching Purchase Order Button
Use the Additional Selection fields at the bottom of the Voucher Builder form to filter for the purchase orders you want. Then when you click the button, matching lines in the grid are selected, based on the filter conditions you specified.
The system selects the first matching row in the grid, and then checks its Fixed Rate, Exchange Rate, and Include Tax in Cost values. After one row has been selected, only rows with the same Fixed Rate and Include Tax in Cost values as the first selected row can be selected. Also, if the first selected row's Fixed Rate check box is selected, then only rows that have the same Exchange Rate as the first selected row will be selected.
This button will not deselect any row that is already selected. It will only select more rows based on the provided conditions.
