Availability, standard calendar & Resource Availabilty (Threshold)

Hi all,


Our company works a 7 hour day but when we were set up in PPM, our shifts in the calendar were left at the system default  of 8.  Our two questions are:

  • Is this the reason why if a resource has 20 days allocated to various activities, that their Resource Availability (Threshold) shows 17.5?  In answering this, I would appreciate it if someone could either explain how this is calculated or point me to some documentation where I can more fully understand this.
  • We have experimented on Test with updating the calendar to a 7 hour day but the allocations  are always affected.  We were told that the steps to complete this were to change all the resources' Availability to 8 and then to change the standard calendar to 7 hours which would then change the resource's Availability back to 7.  The problem is that this also recalculates the monthly amounts of the resources.  For instance, if the resource had been assigned 14 days to a project, after the changes, they are now showing as having 16 days assigned to the project.  Our current assumption is that we will need to make the changes and then re-enter all the assigned allocations to all resources.  Is there a way to make the changes without affecting the Allocations by period?  If there is not, is there a way to automatically upload the Allocations or do they need to be entered manually?


Thanks in advance,
