I had issues with use of this back in 72, but it would at least work when report called from a button on the form.

I find that with SLX754 it wont operate at all.

SLX Support did come back to me and advised :

The reportaddcondition function probably still exists as a usable function in the LAN client but this class of functions have been superseded by more granular Crystal Reports RDC object model handling functions. I would probably recommend not leveraging these legacy commands as they are not used in any out-of-box functions anymore.

Anyone done work with passing ONE parameter to  report in this manner?

You definitely CAN use it (I do, all the time).

    id = Application.MainViews.ActiveView.CurrentID

    Application.BasicFunctions.ReportClearConditions
    Application.BasicFunctions.ReportAddCondition "EMTB_EVENTS:EMTB_EVENTSID","=",id,"String",""

But, it's limited - the condition must apply to the primary table, no more. If you want a better way of handing it get your hands on the SLX Report Quick Launch bundle (send me an email if you need it). But, basically, you can invoke reports very quickly and easily using it.

Thanks for the reply.

I suspected there was an issue with Extenstion tables, and it is an extension table I was using. I did quickly try it with a primary table  I used the standard SUPPORT TICKET report and passed a ticketid, but it failed on first attempt, so I think I gave up and went back to my real need  

I will send you an email for the SLX Report Quick Launch

Many thanks
