    You have hit on a sore point for a lot of users in CA PPM and the source of much discussion. I take it you are using a calendar other than the standard calendar, correct?


    The links below and the TEC bulletin that I have included (after the links), should answer your question and give you plenty of information to go forward with.


    Allocation/Actuals not Reflecting Resource Availability

    Availability Rate for the Resources - how to change programatically


    From: TEC440068: Why does the Availability field not reflect the calendar set for the resource?


    Why does the Resource Availability field not reflect the calendar set for the resource?


    Resource Availability is a percentage of the calendar hours. It is a rate. If you change the calendar hours the resource's availability will change.


    Either the Availability field was edited which edits the resource calendar, or the resource calendar was edited which is reflected in the Availability field.


    If you want the resources Availability to reflect the calendars shift then reset the resources calendar to the base calendar.
    Example: if you have a standard calendar of 8 hours, and a contractor calendar of 7.75 hours. If the resource is set to the standard then their availability is 8 hours. If you change to the contractor calendar the availability is 7.75 hours.


    If you change back to the standard calendar and edited the resources availability to 7.75 hours. Now change back to the contractors calendar a calculation is done based off of the previous change.


    8 hours divided by 7.75 gives a .969 difference. When you change back to the contractor calendar the calculation is 7.75 times .969 the difference) which equals 7.51. 7.51 is what is now displayed in the availability field.


    To correct this change to the standard calendar. Select your workdays and click on Reset to Base. This will clear edits to the resources calendar. Now when you change between the calendars, the availability will depend on the base calendar shift and not edits to availability which makes changes to the resources calendar.


    NOTE: Making changes to the availability or calendars will impact the amount of processing time needed for Time Slicing job to catch up to these changes.

    I would like to give credit to all those that spent the time answering the availability and calendar questions in the past that I linked to. This is what the community is about.


    Thanks everyone!

    Sound like the availability filed was first set to 7,5 and then the resource was associated with a calendar with 7.5 hour work day.

    To reverse that associate the resource with a calendar that has a 8 hour work day and then set the availability to 8 hours.

    To get what you want then associate the resource with the 7,5 hour calendar.
