How to fix this error?

The data element names should only be adjusted for an SAP System with
maintenance level 4.0 or later, or for which an appropriate upgrade is
just being performed. Check that this is the case - otherwise it is
correct that execution is terminated, since the requirements specified
in the diagnosis are checked internally.
