Guys
I'm back again, need your help on this. This is what I use as patch function.
Patch(BDPinturaProjeto,ThisItem, {UserBDPintura: TheUserName, DateBDPintura: Now(), StatusPaintBDPintura:PaintStatusYes.Text});Set(varsingleScan1, "");Reset('ScanToFind-Engine');Refresh(BDPinturaProjeto)
And this is what I need, patch only if my column under the same sharepoint list empty. List is the Same (BDPinturaProjeto), colum to look before patching (ScannedBDPintura).
Thanks in advance.
