I've seen this a number of times in the past and typically eventually get it resolved but I'm never positive what I have done that fixes it.
From crystal reports, open a previously created crystal report. Run the report and I get a prompt for ODBC (RDO) connection information and it asks for three items SERVER NAME, USER ID and PASSWORD (instead of the usual COMPANY ID, USER ID and PASSWORD). The report has been placed in the menu structure and it works just fine there. Knowledgebase seems to be down at the moment and I'm not finding a match here. What exactly is happening here?
I resolved it this time by going directly to the server and opening crystal there. But from my workstation, I get the above. I'm assuming that somehow or other I have some sort of mismatch in the ODBC driver. Don't recall if I created the report at the server or the workstation (but I suspect it is from the server.
Now that I think about it, I think I'm usually getting this for Sage 100 ERP Advanced.
