Hi @ronhu 

I’m not super familiar with PO reports but I would guess its printed if that information exist so you can probably not turn it off without customizing the report/layout.

I checked a report layout for the report called Purchase Order and it have 2 sections about manufacturer and have these 2 condition controlling if it should be written or not.

For CHANGED_PUR_PART_MANUFACTURERS it is:

count(tns:CHANGED_PUR_PART_MANUFACTURERS/tns:CHANGED_PUR_PART_MANUFACTURERFstring-length(tns:MANUFACTURER_PREF_PART) + string-length(tns:MANUF_PARTS) > 0])+count(tns:CHANGED_PUR_PART_MANUFACTURERS/tns:CHANGED_PUR_PART_MANUFACTURERFstring-length(tns:PREF_MANUFAC_PREF_PART) + string-length(tns:PREF_MANUF_PARTS) > 0])> 0

And for PUR_PART_MANUFACTURERS it is:

count(tns:PUR_PART_MANUFACTURERS/tns:PUR_PART_MANUFACTURERUstring-length(tns:MANUFACTURER_PREF_PART) + string-length(tns:MANUF_PARTS) > 0])+count(tns:PUR_PART_MANUFACTURERS/tns:PUR_PART_MANUFACTURERUstring-length(tns:PREF_MANUFAC_PREF_PART) + string-length(tns:PREF_MANUF_PARTS) > 0])> 0

@ronhu This is controlled by the Print checkbox in the Manufacturers tab of the Supplier for Purchase Part page.

Print
If this checkbox is selected, it indicates that the manufacturer's part number and the manufacturer will be included in the purchase order reports.

Yepp, @matt.watters is correct, noticed when I checked the server code that fetches the data that it is checking a print flag on some of the data; I guess its that print flag.
