DIXF: Field 'Entity' must be filled in on DIXF (AX2012)

On AX2012 CU9 or later, if found it on CU10 for example, if you got this error, you can RUN this scripts. Is an update script of CU9, the entity name is a new field inserted on this version.

ReleaseUpdateDB63_DMF releaseUpdateDB63_DMF = new ReleaseUpdateDB63_DMF();
releaseUpdateDB63_DMF.updateEntityType();

Or, more simple, you can delete all entities, when you reopen the entities form all entities will be created. I know, you don't belive me, but it works.
