It has been working in the same way since NAV 2009, but I still get asked often how this works, so why not write up a quick post on this. I also realize that my prior post on how to create Sales Orders through Web Services was made very complex due to compatibility with NAV 2009.
This post only works in NAV 2009 SP1 and will show how to extend the Order page with a Post function and show how to Create a Sales Order from C# and post it.
Extending the page
First of all, we need to create a codeunit with the function, we want to add to the Order page.
Then we expose this codeunit with the same name as the page we want to extend, without putting a check in the published column
Note: All functions in the codeunit needs to have the first parameter be of the same type as the base record as the page you want to extend, else the page will no longer be available and you will get an error in the event log on the Service Tier.
Now taking a look at the WSDL in a browser will show us the new function as a first class citizen
and we can start using this.
Creating a Sales Order through Web Services
This might seem like repeating myself from a prior post, but that post did contain a lot of other information, which really isn’t necessary if you only target SP1.
Creating an order is a 3 step process:
- Create the Order Header
- Fill out the Order Header and create the Order lines
- Fill out the Order lines
Creating the Order header
Is really simple
Order_Service service = new Order_Service();
service.UseDefaultCredentials = true;
Order order = new Order();
After this we have a Order Number and an empty order – exactly like leaving the order No. field on the Sales Order Page.
Fill out the Order Header and create the Order lines
In this sample I will just fill out the Sell_to_Customer_No – a number of the other Order Header fields will be auto-updated when updating the order
order.Sell_to_Customer_No = “10000”;
Then we need to create the Order lines – in this sample I will create 5. BTW – It is NOT trivial to add an order line after the fact, so I suggest you add the needed number of lines in one go:
order.SalesLines = new Sales_Order_Line;
for (int i = 0; i < 5; i++)
order.SalesLines[i] = new Sales_Order_Line();
Fill out the Order lines
In this sample, I will just create 5 lines with green ROME guest chairs.
for (int i = 0; i < 5; i++)
order.SalesLines[i].Type = OrderPageRef.Type.Item;
order.SalesLines[i].No = “1960-S”;
order.SalesLines[i].Quantity = 1;
That’s it – the order is created and you can find it in the Client.
And at last… – Post the order
Having created the order, now it is time to post the order
As you can see, the function takes a Record parameter, but we give it a Key.
Note, that calling a function does not make an implicit Update – meaning that if you have done changes to the record in C# and call the function, you will get an error when calling update later. Reason – the PostOrder function has changed the record and will tell you that the record was changed by another user.
After calling a function on a page you will need to Re-read the record if you need to do more work.
