This form has a UDCX that apparently submits to a SQL web service. If you don't know what SQL server it submits to, you may need to open the UDCX in a text editor to check. You'll want your SQL DBA to check for triggers on the database - Again, I still think it is likely that this is coming from a SharePoint workflow, but if you can't find it there, you may want to have the DBA check for a SQL trigger.
