Internal error while overwriting a charecteristic value in a class

Hi,

I am overwriting a charecteristic value in a class with a change master.

In CL02 I entered the class and the chnage number and entered in edit mode.

Then I selected the charecteristic view and selected the specific charectristic which value I need to overwrite and then clicked on "Overwrite Value" button.

Now the system has found an internal error: the required characteristic data was not found in characteristics maintenance.

Charecteristic data not found: Internal Error

Please tell me how can I get out of this error.
