purchase permits selecting de-activated products when using supplier product code/names
There is a difficulty in purchasing whereas using the left hand side product form, only active products are displayed/selectable, but if using the right hand side (supplier product) both active and inactive products are displayed/selectable.
They should work the same and only display active products for selection.
This is easy to reproduce.
The only work-around found so far is to go to Product->Product Suppliers and find the entry pointing to the disactivated product and delete it.
