Cleaning Up Part Filled Purchase Orders

I wish to tidy up the Part Filled Purchase Orders in my system but cannot delete them out.  How do I deal with them? 

Solution

Part filled order is created when the Order Quantity does not match the Processed Quantity.

Open the Part Filled Order

Select No to the question about receiving the Suppliers Invoice.

At the Bottom of the screen - indicated by the arrow on the screenshot below - select the Hide fully Processed lines.  This will remove all Products that have been received correctly.

Edit the Order Quantity to match the Receive quantity column, and select the Process button; the Purchase Order it will be removed from your pending purchase orders screen.

 On some occasions, a different message may appear:

        Unable to Process, Quantities are Zero

Untick the Hide Fully Processed box and Process.

Changing the order number quantities will have no impact on your stock.
