>I have this strange program error "Must specify additional parameters." whenever I try to set relationship between two tables using Relations button in Data Session dialog window. When I clicked ignore, I got Environment Manager dialog screen. I don't understand what is causing this strange behavior. I'm unable to set relationship via Data Session window however I have no problem setting relationship manually via the Command window. Then, after manually setting relationship, I went back to the Data Session window and double-clicked on the relationship line in Relations, I got the same error message, after clicking ignore, I got syntax error message, then the Environment Manager window. After clicking Cancel, I got "Function requires row or table buffering mode." Hmm... got any ideas why this is happening?

What is the key of the tag of the child table? May be you use some function that requires additional parameters.
