Hi,

We can run the CRM workflows from JScript, if we know the GUID of the workflow. Below are the execution steps.

Steps :-

• Get the GUID of workflow from name using OData Service  (i.e., Using GetWorkflowIDByName(wfName) function )
• Execute the Workflow using the GUID (i.e., Using TriggerWorkflow(workflowGuid) function)

Below are the JScript functions mentioned in above steps.

function GetWorkflowIDByName(wfName) {

var serverUrl = Xrm.Page.context.getServerUrl();

//Prepare ODATA query to fetch WF GUID by WF Name

var odataSelect = serverUrl + “/xrmservices/2011/OrganizationData.svc/WorkflowSet?$select=WorkflowId&$filter=ActiveWorkflowId/Id ne null and Name eq ‘” + wfName + “‘”;

$.ajax({

type:“GET”,

contentType:“application/json; charset=utf-8”,

datatype:“json”,

url: odataSelect,

beforeSend:function (XMLHttpRequest) { XMLHttpRequest.setRequestHeader(“Accept”, “application/json”); },

success:function(data, textStatus, XmlHttpRequest) {

RetrieveWorkflow(data.d);

},

error:function (XmlHttpRequest, textStatus, errorThrown) { alert(‘OData Select Failed: ‘+ odataSelect); }

});

}

function RetrieveWorkflow(Entity) {

var objFilteredWF = null;

objFilteredWF = Entity;

wfID =null;

//Get the WF GUID from OData result set

if (objFilteredWF != null && objFilteredWF.results != null && objFilteredWF.results.length != 0 && objFilteredWF.results[0].WorkflowId != null) {

wfID = objFilteredWF.results[0].WorkflowId;

TriggerWorkflow(wfID);

}

}

//Trigger WF using WorkflowGUID

function TriggerWorkflow(workflowGuid) {

try{

var soapBody = “<soap:Body>”+” <Execute xmlns=’http://schemas.microsoft.com/crm/2007/WebServices’>&#8221;

+ ” <Request xsi:type=\’ExecuteWorkflowRequest\’>”

+” <EntityId>” + Xrm.Page.data.entity.getId() + “</EntityId>”

+” <WorkflowId>” + workflowGuid + “</WorkflowId>”

+” </Request>”

+” </Execute>”

+“</soap:Body>”;

/*Wrap the Soap Body in a soap:Envelope.*/

var soapXml = “<soap:Envelope “

+” xmlns:soap=’http://schemas.xmlsoap.org/soap/envelope/&#8217; “

+” xmlns:xsi=’http://www.w3.org/2001/XMLSchema-instance&#8217; “

+” xmlns:xsd=’http://www.w3.org/2001/XMLSchema’>&#8221;

+ GenerateAuthenticationHeader()

+soapBody +

“</soap:Envelope>”;

/* Create the XMLHTTP object for the execute method.*/

var xmlhttp = new ActiveXObject(“Msxml2.XMLHTTP”);

xmlhttp.open(“POST”, “/MSCRMservices/2007/crmservice.asmx”, false);

xmlhttp.setRequestHeader(“Content-Type”, “text/xml; charset=utf-8”);

xmlhttp.setRequestHeader(“SOAPAction”, http://schemas.microsoft.com/crm/2007/WebServices/Execute);

/* Send the XMLHTTP object. */

xmlhttp.send(soapXml);

}

catch(e) {

}

}
