The article on my website shows how to do this. Here's part of the code:

* Create the CR Object
loCr = CREATEOBJECT("CrystalRuntime.Application")

* Open the report
loCrRpt = loCr.OpenReport("C:\CR\Cust.Rpt")

* Set the data location 
loCrData = loCrRpt.Database
loCrTables = loCrData.Tables
loCrTables.Item(1).Location = "C:\CR\Customer.DBF"

>Run a Crystal Report, that uses this table as source: So when the CR has been created using table "MyRep.DBF", I want to change the table source into "TempRep.DBF".
>The name of the table can change so multiple users can run the report at the same time.
