The same prefix, used by some other applications, The application is at initial stage, and only one workflow is implemented. So,we feel that, it&#39;s a right time to do this activityen-USTelligent Community 12https://community.appian.com/thread/25349?ContentTypeID=1Wed, 09 Dec 2015 07:02:01 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:ba981a94-28ee-49f4-86e3-d2bc07611f1dharshavYes @sikhivahans, I meant the same it will create a new CDT as it is in Early stages :)<div style="clear:both;"></div>https://community.appian.com/thread/25300?ContentTypeID=1Tue, 08 Dec 2015 16:58:38 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:75589029-d285-408e-9a00-898a1814d025Rahul GunduThanks for info Sikhi :)<div style="clear:both;"></div>https://community.appian.com/thread/25299?ContentTypeID=1Tue, 08 Dec 2015 16:48:54 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:ce558826-3faa-4bd8-bb36-d3bf0fdee908sikhivahans@rahulg That's true, if I am not wrong what @harshav meant to say is, to create a new cdt and use it from now on as you have said that the application is at early stages. And re your understanding that a new data type is created and impact analysis is not done - To the best of my knowledge, it is an expected behavior because Appian forms UUID of a data type by using the attributes namely 'Name' and 'Namespace' which means that if you change either of them Appian assumes that you are working on a different object. The same can be studied at https://forum.appian.com/suite/help/7.11/Custom_Data_Types.html#Properties by going through the 'Namespace' and 'Name' properties and also in the 'Note' part at https://forum.appian.com/suite/help/7.11/Custom_Data_Types.html#Edit.<div style="clear:both;"></div>https://community.appian.com/thread/25291?ContentTypeID=1Tue, 08 Dec 2015 14:48:12 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:5bb6319c-a44f-4433-8de5-17950fcb727eRahul GunduHi Harsha,<br />I went through the same approach. When i import into the system, a new data type (CDT) is created. When i try do impact analysis, it&#39;s not showing dependencies. Might system consider it as a new CDT.<div style="clear:both;"></div>https://community.appian.com/thread/25290?ContentTypeID=1Tue, 08 Dec 2015 14:40:57 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:5c04b2e6-728a-43af-a861-daefa1d6ef88harshavAFAIK, the easiest approach is to download the XSD change the Name in that, and Reimport, thinking that the impact of your work is very less and can be changed easily.<div style="clear:both;"></div>
