How to: Compare Versions of an Object

Applies To: Microsoft Dynamics AX 2012 R3, Microsoft Dynamics AX 2012 R2, Microsoft Dynamics AX 2012 Feature Pack, Microsoft Dynamics AX 2012

In Microsoft Dynamics AX, you can compare two versions of the same application object by using the Compare tool. For example, you can compare a table with an earlier version of the same table provided that version control is enabled. Each version of the application object stored by the version control system is numbered. The Compare tool identifies the differences between two versions and provides action buttons to copy, move, or delete the differences. This topic describes how to compare two different versions of the same application object.


You can also open the Compare tool form on the History form. For more information, see How to: View the History of an Element.
