Hello,
I have an existing item in instrument list like this:

This item's InstrumentListItemKey is "VjF8MHgwN2E3M2U3NmFkOWNmZDI5fDIzMDc3".
When I use PUT "https://selectapi.datascope.refinitiv.com/RestApi/v1/Extractions/InstrumentListItems('VjF8MHgwN2E3M2U3NmFkOWNmZDI5fDIzMDc3')" with Json body:
{
"Identifier": "6099626",
"IdentifierType": "Sedol",
"Source": "BSE",
"UserDefinedIdentifier": "504157",
"UserDefinedIdentifier2": "",
"Order": 23077,
"InstrumentListItemKey": "VjF8MHgwN2E3M2U3NmFkOWNmZDI5fDIzMDc3"
}
The call returns without error but the Source remains unchanged.
Is this the correct way to change Source of an existing item in the instrument list?
Thanks!
