Calculations of the Resource plan Requested, Allocation ,CapacitySummaryQueries :1. How is requested hour calculated after setting the percentage capacity on the operational resource plan2. How the requested allocation hours are calculated and the percentage they show are different from resource plan percentage.3. Requested hours dependancy on the allocation type4. In the Customers case he changed the Resource property Calender event duration to 15 minutes . Need to understand what impact it can have on the requested value in the resource reports?Related LinksI will try to answer them with an example:Let say we have an operational resource planUsersDetails: Group having 3 users with 8 hrs capacity each dayDuration : 2021 - 09 -01 to 2021 -10 -31 (2 months)Percentage capacity = 17Allocation type: monthlyTotal working days : Sep 2021 : 22. and Oct 2021: 21 = 22 +21 = 43Calculation:Planned hours:------------------------------------------The planned hour calculation is straight forward:plannedHours = (Total Capacity plan duration) * (percentage capacity) /100)Then round off the planned hours based on the calendar event property.In our example :Total Capacity plan duration = 43 (total working days)* 8(per day capacity) * 3 (no of users) = 1032Percentage capacity = 17plannedHours = 1032 * 17 /100 = 175.44Round Off:If the calendar event property is 60It means that the minimun unit 1 hrs and rounding off 175.44 will lead to planned hours as 175If the calendar event property is 15It means that the minimun unit 0.25 hrs and rounding off 175.44 will lead to planned hours as 175.25Lets consider the calendar event property is 60Planned hours = 175.Requested Allocation calculation:----------------------------------------------------Requested allocation hour = (total capacity across all users in the duration) * (percentage capacity) /100Then we round off based on calendar event property.In our example:Since we have allocation type as monthly and we have 2 months2021 Sept requested allocation:Total capacity across all users in the duration) = 22 (total working days)* 8(per day capacity) * 3 (no of users) = 528Percentage capacity = 17Requested allocation hour = (528) * (17) /100 = 89.76If calendar event property is 60 requested allocation hour = 89If calendar event property is 15 requested allocation hour = 89.75We will consider calendar event property is 60 requested allocation hour = 89Percent capacity on requested allocation = 89 / 528 *100 = 16.86 %. (So it is not same as 17 on the resource plan)2021 Oct requested allocation:Total capacity across all users in the duration) = 21 (total working days)* 8(per day capacity) * 3 (no of users) = 504Percentage capacity = 17Requested allocation hour = (504) * (17) /100 = 85.68If calendar event property is 60 requested allocation hour = 85If calendar event property is 15 requested allocation hour = 85.50We will consider calendar event property is 60 requested allocation hour = 85Percent capacity on requested allocation = 85/ 504 *100 = 16.87 %----------------------------------------So far we haveResource plan:Planned hours = 175Percentage capacity = 172 Requested Allocation:Sep:requested allocation hour = 89Percent capacity = 16.86 %.Oct:requested allocation hour = 85Percent capacity = 16.87 %.Since the sum of requested allocation = 89 + 85 = 174 (which is not equal to 175 planned hours on resource plan)Resource plan gets updated to 174-------------------------------------------------------------Finally we have:Resource plan:Planned hours = 174 (changed from 175 to match requested allocation hour sum)Percentage capacity = 172 Requested Allocation:Sep:requested allocation hour = 89Percent capacity = 16.86 %.Oct:requested allocation hour = 85Percent capacity = 16.87 %.-----------------------------------------------------If the allocation type is "plan duration"We would only have one requested allocation and the result would look like:Resource plan:Planned hours = 175Percentage capacity = 171 Requested Allocation:requested allocation hour = 175Percent capacity = 16.96 %.We see a difference in percentage here because we do an opposite calculation from hour to get the percentage in requested allocation.For the Requested allocation daily:we apply percentage calculation till the requested allocation level. After that mostly the hours we get on the requested allocation is evenly distributed across the number of working days. The remaining hours if any are assigned back from the beginning of the working daysFor example:We have a requested allocation for 5 days with percent capacity 17 percent:Total hours to allocate considering we have only one user: 5 * 8 * 17/100 = 6.8 = 6 hoursThe 5 days requested allocation dailies would look like thisDay 1 : 2 hrs. (2/8 * 100 = 25%).Day 2 : 1 hrs. (1/8 * 100 = 12.5%).Day 3 : 1 hrs. (1/8 * 100 = 12.5%).Day 4 : 1 hrs. (1/8 * 100 = 12.5%).Day 5: 1 hrs. (1/8 * 100 = 12.5%).
