https://www.aras.com/community/f/development/3824/how-to-use-different-types-of-revisionsHi I want to know if I can use multiple types of revisions in one item type For example, If the classification is Part, I want the revision to start with &#39;A&#39;, and if it is a kit, start with &#39;00&#39; Is it possible?ja-JPTelligent Community 12https://www.aras.com/community/thread/1818?ContentTypeID=1Mon, 23 Jul 2018 15:05:12 GMT916d3f7e-8ddc-42f8-8d45-380822f51406:f1266496-4b26-427d-a1de-e3bd186a548aEli DonahueHi jing9, I agree with Angela about the potential complications of trying to overwrite the standard versioning logic with your own. If you really need your own versioning scheme, it might be better to create one or more custom properties on the ItemType. You can then create your own logic in server events as needed to update these properties without interfering with the default versioning properties. Once you get the custom properties and logic working to your satisfaction, you could simply hide the default fields from grids and forms.

I expect it´s possible to overwrite the default revision with a Method. But the main pitfall are the many additional Methdods that rely on the standard revision scheme. For ItemType Part you would have to change a lot of Methods to handle both revision types, e.g. PE_CreateNewRevision and PE_ChangeItemTransition just to mention two.<div style="clear:both;"></div>
