Hello!

Excelchat Expert

User

similar to the (% difference from previous week function)

User
01/08/2018 - 07:51

except it needs to be % difference from previous 4 week average

Excelchat Expert
01/08/2018 - 07:51

Sure.

User
01/08/2018 - 07:51

it needs to be within the pivot table not calculated off of the pivot table

Excelchat Expert
01/08/2018 - 07:51

Could you show me some sample data?

User
01/08/2018 - 07:51

so a calculated field of some sort within the pivot

Excelchat Expert
01/08/2018 - 07:51

Sure

Excelchat Expert
01/08/2018 - 07:52

Let's see how to do it

Excelchat Expert
01/08/2018 - 07:53

So you want the percentage of?

User
01/08/2018 - 07:53

% difference from previous 4 week rolling average

User
01/08/2018 - 07:54

It needs to either be an automatic calculation in the table or as a calculated field in the pivot

Excelchat Expert
01/08/2018 - 07:54

ok I see

User
01/08/2018 - 07:55

but this is a sample dataset

Excelchat Expert
01/08/2018 - 07:55

Sure

Excelchat Expert
01/08/2018 - 07:55

What is D5 should be in this case?

User
01/08/2018 - 07:55

my dataset is much larger and is connected by an access connection

Excelchat Expert
01/08/2018 - 07:55

Sure

Excelchat Expert
01/08/2018 - 07:56

what is the value in D5?

User
01/08/2018 - 07:57

It needs to be done through a calculated field or some type of access query

Excelchat Expert
01/08/2018 - 07:57

Ok

User
01/08/2018 - 07:57

ive been trying to figure this out for quite some time and have narrowed it down to that

Excelchat Expert
01/08/2018 - 07:57

So far, I think the best way to do this is go through this way

Excelchat Expert
01/08/2018 - 07:58

And then create another column for percentage calcualtion

User
01/08/2018 - 07:58

no

User
01/08/2018 - 07:58

i am running a pivot based off a table connection

User
01/08/2018 - 07:58

I dont have an actual table to manipulate

User
01/08/2018 - 07:59

unless its manipulating the table within access

Excelchat Expert
01/08/2018 - 07:59

Yes

Excelchat Expert
01/08/2018 - 07:59

I think that the easiest way to do so

User
01/08/2018 - 07:59

so this will be done in access?

Excelchat Expert
01/08/2018 - 08:00

Yes. it will be easier

User
01/08/2018 - 08:00

ok how

Excelchat Expert
01/08/2018 - 08:00

I have tried to use pivot table

Excelchat Expert
01/08/2018 - 08:00

But even in pivot table, it is still the save to manully inseert another column for rolling average and percentage calculation

Excelchat Expert
01/08/2018 - 08:01

So, eseentially that will be the same

User
01/08/2018 - 08:01

so how do I add the rolling average in access

Excelchat Expert
01/08/2018 - 08:02

Wait. In excel, there might be a way to do this

Excelchat Expert
01/08/2018 - 08:02

To calculate a moving average, first click the Data tab’s Data Analysis command button.

Excelchat Expert
01/08/2018 - 08:02

When Excel displays the Data Analysis dialog box, select the Moving Average item from the list and then click OK.

Excelchat Expert
01/08/2018 - 08:03

find the data that you want to use to calculate the moving average.

Excelchat Expert
01/08/2018 - 08:03

In the Interval text box, tell Excel how many values to include in the moving average calculation.

Excelchat Expert
01/08/2018 - 08:03

Then tell Excel where to place the moving average data.

Excelchat Expert
01/08/2018 - 08:03

After you finish specifying what moving average information you want calculated and where you want it placed, click OK.

User
01/08/2018 - 08:06

i cant find a data analysis button

User
01/08/2018 - 08:06

nvm

Excelchat Expert
01/08/2018 - 08:07

Can you find from your local MS excel?

User
01/08/2018 - 08:07

it doesnt allow for a dynamic average

Excelchat Expert
01/08/2018 - 08:07

is there any error msg?

User
01/08/2018 - 08:07

if I add another week to my pivot i will have to recalculate

Excelchat Expert
01/08/2018 - 08:08

can you include a larger range?

User
01/08/2018 - 08:08

no

User
01/08/2018 - 08:09

i need for it to be built in to either the pivot as a calculated field or as an access query\

User
01/08/2018 - 08:09

the solution you provided is a manual fix not an automatic calculation

Excelchat Expert
01/08/2018 - 08:10

Yes since from excel level this is the only way to do so

User
01/08/2018 - 08:10

what about access

Excelchat Expert
01/08/2018 - 08:10

If you need a automatic way to do this, you may need to consider access

Excelchat Expert
01/08/2018 - 08:10

Since this is a excel platform, we really not be able to assist with access portion

Excelchat Expert
01/08/2018 - 08:10

We do apologize for this inconvience
