&1 intervals were successfully created

What causes this issue?

The object for parallel processing &V2& works with colocation groups and
it defines &V3& index server. This means that the number of intervals
always has to be a multiple of the number of the index server (here:
&V3&) so that each interval exists for every index server.
The mass activity jobs always select precisely the data of an index
server and it has to be ensured that an interval has to be defined for
all data with each index server.
Therefore, in this case, it is not desired to generate &V4& intervals
but &V1& intervals.
