I’m working on a project where every 5 minutes this robot will run. It will filter through unread emails by subject line, then save the excel attachment to a folder. It will use that path to open the excel files from that folder. The file will have 5 columns: PO Number, Part Number, Serial Number, PO Line, and Morgan Part Number. I want to delete any duplicate rows from the Serial Number column and overwrite the file with the new filtered data. So far, I have been able to do everything up until delete duplicates. Could anyone tell me what activities to use or explain a workflow? (I am fairly new to UiPath)
