How to get available fields in TickHistoryRaw report template type?

I have tested it; the below code is running fine.

ExtractionsContext extractionsContext =
     new ExtractionsContext(dssUri, dssUserName, dssUserPassword);          
string sessionToken = extractionsContext.SessionToken;
Console.WriteLine("Returned session token: " + sessionToken);
var availableFields = extractionsContext.GetValidContentFieldTypes(ReportTemplateTypes.TickHistoryRaw);
foreach (var field in availableFields)
{
  Console.WriteLine(field.Name);
}

It returns the list of content fields.

Domain
History End
History Start
Instrument ID
Instrument ID Type
Sample Data

However, with this TickHistoryRaw, you cannot select which fields to include. They are all included in the output.

What are the versions of ThomsonReuters.Dss.RestApi.Client.dll and ThomsonRetuers.Dss.Core.RestApi.Common.dll used by the application?

I am using 11.1.527.

Could you please check that your DSS account has a permission to use TRTH? You can login via DSS GUI at https://hosted.datascope.reuters.com/. Then, select Report Templates -> Create. You should see Tick History report templates when using Permissioned Template Filter.

From the DATASCOPE SELECT drop down, you should see Report Templates -> Create.

Are they permissioned?

Please use the following code the trace HTTP request and response and then share the output.

ExtractionsContext extractionsContext =
     new ExtractionsContext(dssUri, dssUserName, dssUserPassword);

extractionsContext.ResponseReceived += async (sender, args) => {
    Console.WriteLine("\nRequest: {0}\n", args.Request.RequestUri);
    Console.WriteLine("\nResponse Status Code: {0}\n", args.Response.StatusCode);
    Console.WriteLine(args.Response.Headers.ToString());
    if (args.Request.RequestUri.ToString().EndsWith("RequestToken")) return;
    var contents = await args.Response.Content.ReadAsStringAsync();
    Console.WriteLine("Content:\n {0}", contents); 
};

 string sessionToken = extractionsContext.SessionToken;
 var availableFields = extractionsContext.GetValidContentFieldTypes(ReportTemplateTypes.TickHistoryRaw);
 foreach (var field in availableFields)
 {
     Console.WriteLine(field.Name);
 }
 Console.WriteLine("Press Enter to exit");
 Console.ReadLine();

This could be a permission issue, if the content field is also empty for other TickHistory templates:

extractionsContext.GetValidContentFieldTypes(ReportTemplateTypes.TickHistoryTimeAndSales);

extractionsContext.GetValidContentFieldTypes(ReportTemplateTypes.TickHistoryMarketDepth);


extractionsContext.GetValidContentFieldTypes(ReportTemplateTypes.TickHistoryIntradaySummaries);

You can contact your TR's account team to verify the permission. Otherwise, please provide us with your DSS username. Then I can contact the DSS support team to verify it.

I see. I will contact TRTH support team to verify this issue.
