Can I Edit this field on the purchase order, I want it to say Vendor Item Name, rather than Vendor Name

Not entirely sure if you can...According to SuiteAnswers 14006, "This column doesn't display in the form by design and the columns display options cannot be modified."

Thanks, Vendor Name Is misleading, that could mean which vendor you are buying this item from. they should at least allow to edit the field name, for whatever reason they don't allow you to hide

"Enhancement 90617 has been created requesting the ability to hide the column in the form". Looks like it might be something that they will be looking at changing in the future

thanks yeah I saw that, will attach to that enhancement
