How to Control Element Versions?

Version control of MDM dictionary can be set up only in the desktop application.

An MDM dictionary is considered a version one if version history is logged for element values. Value actual range - dates of start and end of action - is specified for each dictionary element.

Element version may change after entering new values of element attributes and on moving of element by dictionary hierarchy, as well as on moving of element under a new parent element.

Setting Up MDM Version Dictionary

To set up MDM dictionary version control, select the Elements can Change in Time checkbox on the Description tab.

After that it is possible to set actual range of dictionary elements. When working with dictionary elements the Actuality Date parameter is available on the Dictionary Elements tab.

When changing of actuality date the tree of elements is rebuilt according to the selected value.

NOTE. Discretionary and mandatory access permissions for MDM dictionary elements do not support version control. When permissions for elements of MDM dictionaries are changed, a new version of elements is not created. Regardless of elements version, only actual permissions are taken, that is, the latest of the set permissions.
