Hi, I wanted to identify a response to a request. I was wondering if there was an identifier that I can get from subscribing, so I can easily match a response to a previous request?
I'm guessing the question is about RData object of DEX2 library of legacy Eikon COM APIs. If this is correct, I'm afraid RData object does not provides any means to match the OnUpdate event to the request. The object is not designed for the use case of sending multiple requests in quick succession using the same instance of the object. If you need to send several requests in quick succession use a separate instance of RData object for each request. This way you will not have a problem of matching responses to requests.
