Generate an Invoice from an Opportunity Using .NET or Jscript in Microsoft Dynamics CRM 2011

This illustration shows how to generate an invoice from an opportunity  in Microsoft Dynamics CRM 2011 with GenerateInvoiceFromOpportunityRequest.   This example will be given in Jscript (SOAP) and in C# (.NET).

Ok, here is what the code looks like!

First in C#:

GenerateInvoiceFromOpportunityRequest req = new GenerateInvoiceFromOpportunityRequest();
req.OpportunityId = new Guid("D911C1BD-23DA-E011-94B4-1CC1DEF177C2");
req.ColumnSet = new ColumnSet(true);
GenerateInvoiceFromOpportunityResponse resp = (GenerateInvoiceFromOpportunityResponse)service.Execute(req);

//use returned invoice
Invoice order = (Invoice)resp.Entity;

Now here is the Jscript nicely formatted by the CRM 2011 SOAP formatter. Available at: http://crm2011soap.codeplex.com/

Now in Jscript


This example is asynchronous, if you want to learn how to make JScript SOAP calls synchronously please visit this post: http://mileyja.blogspot.com/2011/07/using-jscript-to-access-soap-web.html

To understand how to parse the response please review my post on using the DOM parser.

http://mileyja.blogspot.com/2011/03/microsoft-dynamics-crm-2011-parsing.html

Now you can call the SDK.SAMPLES.GenerateInvoiceFromOpportunityRequest  function from your form jscript handler.

Thats all there is to it!

I hope this helps!
