I want to interface a purchasing application via web services so my intent is not to modify anything in NAV but to enable web services for built in pages and codeunits to do the following;
1. Create a Purchase Order
2. Modify a Purchase Order to enter Vendor Invoice and receipt quantity
3. Post a Purchase Order Receipt
4. Create a Purchase Invoice.
I'm currently an ISV running the Demo license for testing. From what I can tell, I can do option's 1,2 and 4 by simply using the Page web service for the Purchase Order. Option 3 seems to be available as a codeunit however I can't see how I can call it to actually post unless I create a code unit and tie it to the Purchase Order page with code to call the Posting Routine, which requires I modify a page and add a code unit. Both requiring a Developer license. I was originally thinking that if the pages and codeunits were available by default in the installation that I could just set them up as web services and call them from my purchase application. Can anyone tell me if I'm mistaken on this and if there is a way to use the codeunits from web services to do what I want to do?
Jim
