Printing UserID on SSRS reports

Yeah one of those things. Not displayed - you just have to know.
I just happened to see a couple threads, referenced here:

  • never noticed any mention in the standard documentation but… could be in there?

CallContextClientData_ and CallContextBpmData_

e.g.
LEFT OUTER JOIN CallContextClientData_" + Parameters!TableGuid.Value + " T2
ON T1.Company = T2.CurrentCompany"

Or
LEFT OUTER JOIN CallContextBpmData_” + Parameters!TableGuid.Value + " T3 ON T1.whatever = T3.whatever"
