I accidentally clicked the Close button on a Blanket Purchase Order. How do I re-open it? There is no Closed column available on the form

You'll need to open the lines (opening even one line will put the PO back to Pending but you'll want to open all the lines).

@AI1 If you don't see a Closed column, you may need to edit the form to display it

There is no option to display it on the form. It is not an available line field. I did find a SA article that says the only option is to remove all lines from the blanket PO and re-add them back on, because the Closed field is not available to Blanket PO transactions....smh
