Hi there, I need to invoke a BusinessRule via SData after creating an entity. I used the approach of Mike LaSpina in this thread but without success.

Here's the code:

            SDataServiceOperationRequest sreq = new SDataServiceOperationRequest(base.NewSDataService())
            {
                ResourceKind = "licenseorders",
                OperationName = "GetDataFromServiceNetMailWrapper"
            };
            sreq.Entry = new AtomEntry();
            sreq.Entry.SetSDataPayload(
                new SDataPayload
                {
                    ResourceName = string.Format("LicenseOrder{0}", sreq.OperationName),
                    Namespace = "http://schemas.sage.com/dynamic/2007",
                    Values =
                    {
                        { "request", new SDataPayload
                            { 
                                Values =
                                {       
                                    { "licenseorderId", licenseorder.id }
                                }
                            }                                                               
                        }
                    }
                });
            AtomEntry entry = sreq.Create();
            SDataPayload response = entry.GetSDataPayload().Values["response"] as SDataPayload;
            result = response.Values["Result"].ToString().ToLower() == "true";

I'm using the SDataCSharpClientLib v1.2.2.1335 (via NuGet)
The licenseorder has been created before and the licenseorder.id is valid.
The value licenseorderId is the parameter that the wrapper function needs to perform the wrapped operation.

It gives me the following error:
(404) Not found.

The uri being called is:
http://servername:port/sdata/slx/dynamic/-/licenseorders/$service/GetDataFromServiceNetMailWrapper

If I open http://servername:port/sdata/slx/dynamic/-/licenseorders/$service in a browser, it shows me the original BusinessRule named GetDataFromServiceNetMail but not the wrapping method.

Am I doing something wrong? Am I using the wrong version of the SDataCSharpClientLib?

IF you don't see the business rule when you list them with http://servername:port/sdata/slx/dynamic/-/licenseorders/$service then it's not seen as a business rule, which is why you're getting the 404. The code looks right.

You are sure you have a business rule named "GetDataFromServiceNetMailWrapper" and you've built & deployed the SData portal since creating it? 

To be sure, I checked once again for my BusinessRule and found a little error: it waited to get an object passed to it instead of a string. Then I've deleted the contents of the build directory and the SData website, reloaded the project, made a full build and deploy and it appeared!

Now I'm getting an internal server error when running the code above, but that's probably because of bugs I produced ^^

Thanks a lot!

One last thing: the value "response" in the responsePayload does not contain another payload, but a SDataSimpleCollection. So the last lines should be something like:

AtomEntry entry = sreq.Create();
SDataPayload responsePayload = entry.GetSDataPayload();
if (responsePayload != null && responsePayload.Values["response"] != null)
    result = ((SDataSimpleCollection)responsePayload.Values["response"])[0].ToString().ToLower() == "true";

The code suggested by Mike LaSpina didn't work for me.

Also, there is another SData library, the DotNetSDataClient, which is newer and a bit simpler to use than the SDataCSharpClientLib. It has support for things like linq & async requests. It also has docs. You can see the docs for doing service requests using the DotNetSDataClient here http://developer.saleslogix.com/DotNetSDataClient/whitepaper/service_operations.html

Either library is valid to use, although I believe they push the DotNetSDataClient library as the preferred one to use. Just thoguht I'd mention it's out there too. It can be found on NuGet or the git repo here https://github.com/Saleslogix/DotNetSDataClient
