Supplier invoice number
On WebBrowser how to display Supplier Invoice Number instead of Purchase Number. Ditto for Bills screen (Purchase Number description altered to Bill Number on this screen).
On Desktop version you can alter this via Setup -> Preferences -> Purchases. No such option on the online version.
There must be a way to alter the screen columns.
Thanks anyone.
Sorted, it is on the screen to the right of supplier name.
