Hi there,
I am setting up procurement for certain products and have gone through the set up guide and have run into a problem when adding line items to a purchase requisition.
I have set up my procurement category, procurement catalogue, procurement hierarchies and associations, purchasing policies as well as all my approved vendors.
When I go into purchase requisition lines the following is seen. I can see my procurement categories but no items (I have added my products to my catalogue)

If i try add an item from the catalogue manually I get this error.

I am not sure what I overlooked but any help would be greatly appreciated.
Thanks in advance.
