How to get Index Name and Constituents in the same Extraction

Hi, if I set up an instrument list with several Index Chain RICs, they become expanded in the extraction to their constituents. Is there a possibility to see in the extraction, from which index each RIC was expanded i.e. a reference to the original Chain RIC per entry? Is there a special report Template/Field to achieve this? The desired format would be:

<parent index (or parent index chain RIC)>;<RIC>;<ISIN>

Hello @f.heuschen,

Depending on what request type you are running, Identifier included with the result is the original request Identifier, so may carry the info you are looking for?

For example:

{
  "ExtractionRequest": {
    "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.EndOfDayPricingExtractionRequest",
    "ContentFieldNames": [
      "Ask Price",     
      "CUSIP",
      "Exchange Code",
      "Exchange Description",
       "RIC",
      "Ticker"
    ],
    "IdentifierList": {
      "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",
      "InstrumentIdentifiers": [
        { "Identifier": "438516AC0", "IdentifierType": "Cusip" },
        { "Identifier": "IBM.N", "IdentifierType": "Ric" },
         { "Identifier": "0#US30YT=TWEB", "IdentifierType": "ChainRIC" }
      ]
    },
    "Condition": null
  }
}

results in

     {
            "IdentifierType": "ChainRIC",
            "Identifier": "0#US30YT=TWEB",
            "Ask Price": 152.60938,
            "CUSIP": "912810QK7",
            "Exchange Code": "TWB",
            "Exchange Description": "TRADEWEB",
            "RIC": "912810QK7=TWEB",
            "Ticker": "UST"
        },
        {
            "IdentifierType": "ChainRIC",
            "Identifier": "0#US30YT=TWEB",
            "Ask Price": 160,
            "CUSIP": "912810QL5",
            "Exchange Code": "TWB",
            "Exchange Description": "TRADEWEB",
            "RIC": "912810QL5=TWEB",
            "Ticker": "UST"
        },
        {
            "IdentifierType": "ChainRIC",
            "Identifier": "0#US30YT=TWEB",
            "Ask Price": 169.98438,
            "CUSIP": "912810QN1",
            "Exchange Code": "TWB",
            "Exchange Description": "TRADEWEB",
            "RIC": "912810QN1=TWEB",
            "Ticker": "UST"
        },

Does this help?

Thanks for the answer.. is this only the case on using the REST Service? I tried the same with the DSS Frontend ( EOD Request with RIC & ISIN as fields) and here the parent chain RIC was not included in the created file...

Hello @f.heuschen,

From my looking via DSS GUI request this does not seem to be the case. However, to get a definitive answer, if there is an option to obtain this info with results via DSS GUI, it is best to involve a Refinitiv DSS specialist via Refinitiv Helpdesk Online -> DSS.
