IDataServiceUpdateProvider needed to update via OData WS

mspace

Hi,

I'm currently experiencing and testing the OData webservice framework for Navision 2013.

I have followed this example (http://msdn.microsoft.com/en-us/library ... 0(v=nav.71).aspx) and code builds fine and
I'm able to retrieve data. Here is my code:

NAV nav = new NAV(new Uri("http://192.168.10.162:7048/DynamicsNAV70/OData/Company('CRONUS International Ltd.')"));
nav.Credentials = CredentialCache.DefaultNetworkCredentials;

// Via LINQ get all customers
var customers = from c in nav.Customer
//where c.Location_Code == "YELLOW"
orderby(c.Name)
select c;

// Write customer list to console
foreach (var c in customers)
{
Console.WriteLine(c.Name);
}

Console.ReadLine();

Console.WriteLine("Printing list of current customers:");
PrintCustomersCalledCust(nav);

Console.WriteLine("Adding new customer.");
Customer newCustomer = new Customer();

newCustomer.Name = "Customer Name";
nav.AddToCustomer(newCustomer);
nav.SaveChanges(); // <== Exception thrown here !!!!

Console.WriteLine("Printing list of current customers:");
PrintCustomersCalledCust(nav);

newCustomer.Name += "Changed";
nav.UpdateObject(newCustomer);

nav.SaveChanges();
Console.WriteLine("Printing list of current customers:");

PrintCustomersCalledCust(nav);


However it seems that the example found at MSDN above has not taken into account that you need an IDataServiceUpdateProvider if you want to post inserts/updates
back to Navision.

I'm getting this error (inner exception):
The data source must implement IDataServiceUpdateProvider to support updates.

Is it really necessary to write a provider in order to update data ? :?

I have found some code examples to implement IDataServiceUpdateProvider (http://blogs.msdn.com/b/alexj/archive/2 ... pdate.aspx),
but I find it difficult to put together all the pieces on the specific pages.

Does someone have a working complete code based on Alex' article ?

Cheers...

Hello,

If your version is 7.0 then OData is not writable. Only from version 7.1... - (NAV 2013 R2).

Try SOAP or upgrade your system to new version.

I'm running NAV 2013, not R2 ... that explains the problem with updating data from an OData webservice.

Is there any sample code where I can see how a SOAP webservice (that updates NAV) I can get some inspiration from ?

Sorry for cross-forum posting ( :oops: ), can this thread be useful?
