Thanks for your feedbacK,May be my question was not correctly stipulated. I got an answer from Refinitiv support.The RIC search process using ISIN and Market return randomly Price RIC or Yield RIC.The Yield RIC has letter 'Y' before '=' in the RIC.

To force Yield RIC when applicable i can simply add 'Y' befor '='.

Example : Price RIC --> BE77446=MK become Yield RIC BE77446Y=MK

Hello @benyounes.benali-ext,

I would like to suggest:

Taking a look at the full list of fields with brief descriptions that are part of T&C. You can either run

{
                {protocol}}{
                {host}}{
                {api}}Extractions/GetValidContentFieldTypes(ReportTemplateType=ThomsonReuters.Dss.Api.Extractions.ReportTemplates.ReportTemplateTypes'TickHistoryTimeAndSales') 

See REST API Tutorial 4: On Demand tick data extraction for the complete explanation on how to do it

or

reference Tick History Data Coverage Guide, it lists all the fields in T&C with brief descriptions. This way you may identify the content that you are looking for.

If you are unable to locate the content you are looking for, to get a definitive answer on content, as a customer, please contact Refinitiv Helpdesk Online -> DSS to raise a support case on content.

The members of this developer community forums are mostly developers and moderators are API experts, so we will not have in-depth expertise in content.

Hope this answer enables you to proceed.
