RE: Best way to propagate CDT Changes especially removing columns

Hey sudhakaraa,

I can answer a few of your questions.

When a Datatype is changed, any Object that is not currently being edited is updated with the new Datatype.
I can't give you the name of a plugin that would automatically propagate all of your changes, but there is existing functionality in Appian that shows all impacted objects for you to manually edit.

While browsing your Application, check the box to the left of the Datatype object that you've just modified. Above the grid, next to the button that allows you to create a new object, a "DEPENDENTS" button should appear. You can click that to see all objects in your application that reference the Datatype object that you just modified.
As for making changes to Datatype who reference DB tables that have recently changed, you can download the XSD for that Datatype using the gear in the top right of the screen. You can edit that XSD then reupload it (using the same gear in the top right of the screen) to make any changes to the Datatype and it's relationship with the Database. The XSD format is fairly intuitive and easy to work with.

Thanks,
Jake
