Resolving ‘A column named already belongs to this table’ Error

When getting an error similar to this in a form/activity:

To Resolve:

Check fcEventCreate table in the XMPro database with the EventID of your activityA specific step in a process.  It will be the user interface for that step (web form or a screen), for example, the Leave Application (screen interface or web form) will be the first Activity in the Leave Requisition process.  The Leave Application Authorization will be the second step or Activity in the Leave Requisition process.  One Process can have multiple activities., there might be two rows in fcEventCreate table for this particular activity.  Remove the one that is not required should solve the problem.

Example

The image below for activity (EventID 74), shows there are two rows with ‘First Activity’ as ‘Create Type’. There should only be one row for any activity/EventID in fcEventCreate table. Removing the unnecessary/duplicate row should solve the issue.
