Beas: Absence of the Attendance Module does not affect the scheduling of the resource in which the personnel have been linked to

Following Scenario:

If you have two personnel linked to the same resource  

User1 

User2  

Then your resource will consider these two users on the calculation of the scheduling of the resource 

However, if you register on the attendance module any absence for any of the two employees linked to the resource

This absence will not affect the calculation of resource scheduling
