I’m currently working on a Workflow for a customer.
The Workflow shall create Purchase Orders with Purchase Order Lines for different parts.

For this I need to pass the buy unit price but before I can do that, I would like to fetch the correct price first.
From debugger I can see that IFS calls PurchaseOrderHandling.svc/ValidateBuyQtyDue.
When trying to call this api from the workflow I get the following message:
This references unsupported datatype(s)

and I cannot seem to get it to work. Any expirence with this or suggestions to other api to use?
OBS: price list are used for some Supplier for Purchase Parts.
