Deleting an open Purchase order (PO) removes it from the Buy screen and eliminates the respective Expected quantities for related materials in the Inventory tab.
To delete a PO:
Navigate to the Buy screen and find the PO in the list. Click on it to open the PO card.
Click on the 3-dots at the top corner of the PO card and select "Delete" from the drop-down menu.
Click Yes in the pop-up window to delete.
Caution! Deleting Received Purchase orders decreases the In stock quantity for the relevant materials in the inventory list.
You can also delete Purchase orders in bulk directly from Buy screen by selecting the relevant Purchase orders and clicking on Delete icon.
