How can I calculate per hour, per day volumes if one or multiple days' data is selected?

[louwen]

hi. I have a scenario where i need to calculate the hourly and daily volume work effort of staff using specific criteria such as the days are 7 hours and days are 21 days in the month.

Easy enough i know, except i am using SLICERS to select the relevant month as well as the specific day in that month. This means that if I select one day only, the day data should only show that day and obviously the hourly average. But if I select multiple days in my SLICER I need some sort of formula to step in and then re-calculate the averages accordingly knowing that more than one day has been selected?
Below is an example of what I am looking at;

The Volume is for two days as selected via SLICER.

A	B	C
Actual Volume	Per Hour (7 hrs)	Per Day (21 days)
15

What is your Slicer controlling?

Hi. Controlling multiple Pivot sheets that are linked to a database. Made them to keep users from having to filter on multiple sheets and by accident mess the whole process up.

Can you use GETPIVOTDATA to return the count of days from one of your pivot tables?

I do have GETPIVOTDATA formulas, yes. they help consolidate some data onto this front sheet. however, in this case i use them to consolidate the relevant data to another sheet an from that sheet do a VLOOKUP to this Column.

So can you use it to count the days?

Hi. Unfortunately the days or months data are from a live database. so no. I can only select the specific day eg Monday September 15 2014 as part of the filter on the pivot.

Can't you create a pivot table (linked to your Slicer) like this to count the dates?

Excel 2010
	A	B	C	D	E	F
1	Date		Row Labels	Count of Date		7
2	01/09/2014		01/09/2014	1
3	02/09/2014		02/09/2014	1
4	03/09/2014		03/09/2014	1
5	04/09/2014		04/09/2014	1
6	05/09/2014		05/09/2014	1
7	06/09/2014		06/09/2014	1
8	07/09/2014		07/09/2014	1
9			Grand Total	7

hi. Not sure if this will help, as it will need to be done for more than a year worth of dates as the data available goes back 3 years.

I don't see how the number of dates makes any difference.
