I am very sorry, but I don't know how Concur maps the import file received from the bank - we have multiple card feeds from different providers (MasterCard, VISA, AirPlus) and in all cases it just worked...Concur mapped the transaction reference number and it is the same as we see in the CSV file we download from each provider for matching.
I was also lucky that when I came to start our this automated clearing process, our SAP system had already been enabled to let me select SGTXT in OB74, so I assume those notes you mentioned have been applied to our system, but this is maintained by our SAP Technical team.
Sorry I cannot be more helpful with your questions... I hope you are able to resolve the situation with Concur and the field mapping.
