Diagnosis
When a table is activated as a dependent table, an ADD FIELDS isencountered, although this should not happen when a dependent table isactivated. The reason for this is that the table in question hasalready been activated with ADD FIELDS during this system update and aninactive nametab already exists. When the table is activated as adependent table, the ADD FIELDS is detected again, since the activenametab has not yet been brought into line, but the ABAP/4 Dictionarysources have already been brought up to date.
