I took a look at Standing Orders. They are editable and filterable, and you can assign them their own PO number series. In all other respects they offer the same functionality as Templates, so I don't even understand the reason for having Templates. Can you offer one?
The only thing I can think of (and this is stretching) is that Templates are stored in their own data table, while Standing Orders are stored in the same table as PO's/Receipts. Honestly, though, I think it makes more sense to be in the same table.
But I still have the same requests for Standing Orders as for Templates - the ability to multi-select, and a date field that gets updated when the Standing Order is turned into a PO (not just when it is physically edited) and can be displayed on the grid.
