User 18/07/2018 - 06:32
ok, I have just copied them into the spreadsheet here
User 18/07/2018 - 06:33
So I am looking to match data included on "timesheet" with the project and date range on "reporting"
Excelchat Expert 18/07/2018 - 06:33

Excelchat Expert 18/07/2018 - 06:33
let me have a look
User 18/07/2018 - 06:33

Well, I need to figure out what formula will help me to analyse the data entered into "timesheet"
User 18/07/2018 - 06:37
So I need to enter something starting at C14 that counts how many hours have been spent working on 1:1 Positive People within the date range 25-5-18 to 14-6-18
Excelchat Expert 18/07/2018 - 06:37
okay
Excelchat Expert 18/07/2018 - 06:38
Should this be a different table, where you have activity, start date , end date and time spent in hours
Excelchat Expert 18/07/2018 - 06:38
?
User 18/07/2018 - 06:40
You mean like the "timesheet" one? where they enter Date ; Project and Hours?
Excelchat Expert 18/07/2018 - 06:41
No, just aggregate of the table in timesheet
Excelchat Expert 18/07/2018 - 06:41
You can chnage the date range ad the formula should show time spent accordingly
User 18/07/2018 - 06:41
hmmm what might that look like? And I guess I would still need to same formula to transfer the data from "timesheet" to "reporting"?
Excelchat Expert 18/07/2018 - 06:43
I am getting confused here... my understanding is you want analyze the data in timesheet by looking at how many hours where spent working on a particular activity during a time frame
Excelchat Expert 18/07/2018 - 06:43
Is my understanding correct?
User 18/07/2018 - 06:43
yes that's right and I want that to be shown on the reporting page
Excelchat Expert 18/07/2018 - 06:44
So, from the timesheet sheet, you want to populate the table in reporting tab
Excelchat Expert 18/07/2018 - 06:44
correct?
User 18/07/2018 - 06:44
yes :) so the hours need adding up in relation to each project on the reporting page
Excelchat Expert 18/07/2018 - 06:45
Easier way would be to use pivot table where do don't have to create formula
Excelchat Expert 18/07/2018 - 06:45
It can look be formatted as in the reporting tab
Excelchat Expert 18/07/2018 - 06:45
Should I go ahead with this?
User 18/07/2018 - 06:46
yes please, Ive never used pivot tables
Excelchat Expert 18/07/2018 - 06:46
Give me few minutes while work on it
User 18/07/2018 - 06:46
ok
Excelchat Expert 18/07/2018 - 06:51
I have created a new sheet Reporting Pivot
User 18/07/2018 - 06:52
Thank you! :)
Excelchat Expert 18/07/2018 - 06:52
I hope this solves your problem
Excelchat Expert 18/07/2018 - 06:52
The value in the pivot table is dependent on the data in timesheet tab
Excelchat Expert 18/07/2018 - 06:53
Once you update the timesheet data, the only other thing you would have to do is refresh pivot table
User 18/07/2018 - 06:53
ok brilliant so does that mean that as additional project are added this will automatically be reflected in the pivot table?
Excelchat Expert 18/07/2018 - 06:53
Yes, but you would have to refresh the pivot table
Excelchat Expert 18/07/2018 - 06:54
Let me show you how
Excelchat Expert 18/07/2018 - 06:54
Select a cell on the pivot table > Analyze Tab > Refresh > Refresh
Excelchat Expert 18/07/2018 - 06:55
You find analyze tab on the top of the excel window
Excelchat Expert 18/07/2018 - 06:55
Did you follow?
User 18/07/2018 - 06:55
Got it, that's fantastic!
