>I just checked the docs and a program. The hasChanges method exists on the DataSet but not the datatable. Because I used datatables throughout the program, I created the method for that in the biz object. I could have used the table.dataset.haschanges()........ but at the time(1 year ago), this seemed to be a better way to do it.

Interesting - thanks for the follow up. Some of the things the included and excluded in the CF are a little weird.
