Hi @Taha Zubair 

I suggest the following

• List down all the fields for an uncompleted Task. eg Status=”Not Started”, PercentCompleted=”0”, etc
• Completed the Task normally. 
• List down all the fields for this completed Task. 

I’m using SPO (so some fields might differ to your SP 2019 fields)

After programmatically updating the Task Item

Viewing in the Workflow Task List

Hi Garrett Rookie.

Thank you very much for your response.

Actually we don’t have Nintex Task Outcome3 Filed instead we have only Outcome.

But I found a way around by approving the task using Soap services as below:

      var webSvc = siteURL + "/_vti_bin/NintexWorkflow/Workflow.asmx";

      var rqst = '<?xml version="1.0" encoding="utf-8"?>';

      rqst += '<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:m="http://nintex.com">';

      rqst += '<soap:Header>';

      rqst += '</soap:Header>';

      rqst += '<soap:Body>';

      rqst += '<m:ProcessFlexiTaskResponse2>';

      rqst += '<m:comments>' + varComments + '</m:comments>';

      rqst += '<m:outcome>' + varOutcome + '</m:outcome>';

      rqst += '<m:spTaskId>' + varTaskId + '</m:spTaskId>';

      rqst += '<m:taskListName>' + varTaskListName + '</m:taskListName>';

      rqst += '</m:ProcessFlexiTaskResponse2>';

      rqst += '</soap:Body>';

      rqst += '</soap:Envelope>';

      

      $.ajax({

        type: "POST",

        url: webSvc,

        contentType: "text/xml;charset=UTF-8",

        data: rqst,

        dataType: "xml",

        success: function (data, status, xhr) {         

          console.log('OK: ' + status);

        },

        error: function (data) { 

        console.log(data.responseText); 

        }

      });

Thanks,
Taha Zubair
