To set the Max Active benches:
Select the relevant activity from the Activities table.
Expand the record tree to the required level of granularity.
Select record from record tree.
Set the value for the maximum active benches.
Setup > Maximum Benches.
Setting the value for a parent node will result in all child nodes inheriting the same value.
