Hi Gurus,

There are list of technicians under two different group. In that there are few technicians working under same workskills (eg. Electrician)

When an activity is created in the bucket and during routing, it should get assigned to 3 or 4 technicians from different teams.

This can be done only while grouping all the technician in a single group and assigning it to them, but how can we do without grouping and assigning to a list of technicians.

Thanks in Advance,
