OK. I think I'm getting the idea. There are several ways I can see of doing this 1) You could have a new service template - SQL builder. When you add it to the workflow, you need to select which WSDL activity it is to build for. Then when it is added it creates an SQL builder activity and also a connection to the WSDL activity. 2) You could add "with SQL builder" as a new option when adding a WSDL activity - alongside "Add to workflow" and "Add to workflow with name". 3) You could do it as a new configuration ability for a WSDL activity. 4) You could do it in a similar manner to setting a constant value (or adding an XMLSplitter) i.e. you click on a WSDL activity's port and do "create SQL query" which pops up a dialog and then inserts the SQL builder activity. > Thanks. > Wei Alan ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
