Modify UCM Workflow History

If you want to generate reports on Workflow, you may noticed two tables in UCM schema called DocumentHistory and WorkflowHistory. Both of them audits and saves all actions  done.

But those tables have few fields, notice DocumentHistory table

What if we want to add new fields to to the history, why? because I want to track changes on some custom fields and report them, another example if I want to track updates done on metadata fields using "Update" action.

Good news UCM is great, we can add our custom fields to the table (simply by modifying table structure), like adding xComments

At the end we can overwrite UCM query that inserts to the table actions' history. So we will modify IdocHistory, as the following

<tr> <td>IdocHistory</td> <td>INSERT INTO DocumentHistory (dActionMillis, dActionDate, dID, dRevClassID, dUser, dDocName, dAction, dSecurityGroup, xComments) values(?, ?, ?, ?, ?, ?, ?, ?, ?)</td> <td>dActionMillis int dActionDate date dID int dRevClassID int dUser varchar dDocName varchar dAction varchar dSecurityGroup varchar xComments varchar</td> </tr>
