Cannot retrieve basic Value Chain fields

Marceau

Hello,

I am trying to retrieve the Value Chain (VCHAIN) data via the latest Python API (refinitiv-data).
However, even the most basic Supply Chain fields fail with entitlement errors.

Here is the exact request I am making:

import refinitiv.data as rd
rd.open_session()

fields = [    "TR.SCRelationship",    "TR.SCRelationship.RelationshipType",    "TR.SCRelationship.SCOrgName",    "TR.SCRelationship.SCOrgRIC",    "TR.SCRelationship.SCOrgISIN",    "TR.SCRelationshipConfidenceScore",]
resp = rd.get_data(    
universe=["MSFT.OQ", "AAPL.OQ"],    
fields=fields)

And here is the exact error returned by the API:

refinitiv.data._errors.RDError: Error code -1 | Unable to collect data for all requested fields. Requested universes: ['MSFT.OQ', 'AAPL.OQ']. Requested fields: ['TR.SCRELATIONSHIP', 'TR.SCRELATIONSHIP.RELATIONSHIPTYPE', 'TR.SCRELATIONSHIP.SCORGNAME', 'TR.SCRELATIONSHIP.SCORGRIC', 'TR.SCRELATIONSHIP.SCORGISIN', 'TR.SCRELATIONSHIPCONFIDENCESCORE']

My questions:

1. Are these fields (TR.SCRelationship.*) still available in the modern refinitiv-data API?
2. Are they part of Value Chain Basic, or did they move into a different entitlement?
3. Is there a new recommended way to retrieve:
   • supplier name
   • supplier RIC
   • supplier ISIN
   • relationship type
