Hi Manoj,
Before answering your question may I know what scenarios you are using in Appointment booking.
Capacity Pots enables appointment booking functionality to book jobs of a certain job type without assigning directly a resource. The actual assignment between the created appointment and the appropriate resource is done with MRS functionality either manually or by optimizer.
Capacity Pots have basic availability maintained at work center level with respect to job type which requires qualification of the resource. Resource with multiple qualifications can be hierarchically mapped
The master data is formed for capacity pots is through various data.So if when you are creating a capacity pot with this field relevancy there is a possibility to have free capacity or matching capacity on the same planning node.Henceforth when you maintain this field you can identify the relevant capacity pots which suits your need.
