Purchase Requisition selecting approved vendor for a catalogue item

Hi,

I am having an issue for an AX 2012 client through the purchase requisition process when adding a Catalogue item and trying to update the preferred or approved vendor details for the catalogue item at the add item line level. I have used this in AX 2012 R2 and it works fine when approved or preferred vendors are setup for catalogues and the correct policies are adhered to.

Am thinking there may be some incorrect setup with either catalogues or policies but they seem to be correct. With this AX 2012 client when I use non-catalogue items and add a product and category the rules work for selecting a vendor account (preferred and approved show) but not when using catalogue items.

Anyone with any ideas of has seen an issue with AX 2012 catalogue items and vendors?
