Error is coming while activating the z table

Hello ,

I have created a z table .

When i activate this table , i get the following error .

Das Aktivieren von Dictionaryobjekten während des

Einspielens neuer Software ist gesperrt (ITSU01,21.08.2014, 17:16:26).

Google translation of above error is :

Enabling dictionary objects during the import new softwware is locked

(ITSU01,21.08.2014, 17:16:26).

Is this a Basis Error?

Thanks ,
