In this field, enter or select the supplier for the invoice using the Lookup tool.

To search using the auto select option, enter several characters of the supplier name or code and press the Tab or Enter key. The selection window opens with a list of suppliers based on those characters. The results include active and inactive records.

Auto selection is available if the AUTOSEL – Auto selection parameter (SUP chapter, INT group) is set to Yes.
