Column for subtraction of grand totals in pivot table - power query useful here?

[heretolearnexcel]

Hi,

I have a table of data that I turned into a pivot table. Here is an example of more or less the data I'm working with:

Date	Type of movement	Product A In	Product A Out	Unit Cost	Unit Cost	Client	Selling Price	Product A in Stock
10/11/19	A	20		3				100
10/3/19	B		10		2	Client A	$25	85
9/23/19	C	5		2				90
9/22/19	B		9		5	Client B	$20	91
9/15/19	A	30		4				70
9/13/19	B		12		4	Client D	$18	35
9/10/19	A	7		5				100
9/02/19	C		8		3	Client A	$25	12
8/24/19	A	10		9				13

<tbody>
</tbody>

I turned the data into a pivot table and ended up with this:

Type of movement	Sum of Product A in	Sum of product A out
B		10
A	20
B		9
B		12
A	30
A	7
A	10
Grand Total	67	31

<tbody>
</tbody>

I would like for the pivot table to display in the Grand Total row the difference between Sum of Product A in and Sum of Product A out, such that the result in the example would be =67-31= 36. I tried adding a formula next to the 31 which, supposing Type of movement= A1, would be in cell C9 and the 31 would be in D9. But if I filter for Type of movement and more values are added, changing the size of the pivot table, then the formula in D9 will no longer subtract the values from the grand total since they will no longer be in the original cells.

I tried using Power Query to changing the Type of movement column so that each unique row value of the column becomes a new column, and then I would be able to work the data to get the results I want, but I can't seem to find a way to do that in Power Query and keep all the corresponding data. The result I would like to get using Power Query would be something like this.

Date		Type of Movement A	Type of Movement B	Type of Movement C	Unit Cost	Unit Cost	Client	Selling Price	Product A in Stock
10/11/2019	Product A In	20			3				100
10/3/2019	Product A Out		10			2	Client A	$25	85
9/23/2019	Product A In			5	2				90
9/22/2019	Product A Out		9			5	Client B	$20	91
9/15/2019	Product A In	30			4				70
9/13/2019	Product A Out		12			4	Client D	$18	35
9/10/2019	Product A In	7			5				100
9/2/2019	Product A Out			8		3	Client A	$25	12
8/24/2019	Product A In	10			9				13

<tbody>
</tbody>

Well... I just realized that wouldn't work for what I want. But still, is there any way to do that in Power Query? And regarding my original question, how could I achieve that with my pivot table?

Thank you in advance.

with table or PowerQuery it is not possible : two the same name of columns, eg: Unit Cost

 

[sandy666]

is that what you want with PQ ?

Date	Attribute	A	B	C	Unit Cost	Unit Cost2	Client	Selling Price	Product A in Stock
11/10/2019​	Product A In	20​			3​				100​
03/10/2019​	Product A Out		10​			2​	Client A	25​	85​
23/09/2019​	Product A In			5​	2​				90​
22/09/2019​	Product A Out		9​			5​	Client B	20​	91​
15/09/2019​	Product A In	30​			4​				70​
13/09/2019​	Product A Out		12​			4​	Client D	18​	35​
10/09/2019​	Product A In	7​			5​				100​
02/09/2019​	Product A Out			8​		3​	Client A	25​	12​
24/08/2019​	Product A In	10​			9​				13​

Yes, that's what I want with Power Query.

 

[sandy666]

so try this

[SIZE=1]// Table1
let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    Type = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Type of movement", type text}, {"Product A In", Int64.Type}, {"Product A Out", Int64.Type}, {"Unit Cost", Int64.Type}, {"Unit Cost2", Int64.Type}, {"Client", type text}, {"Selling Price", Int64.Type}, {"Product A in Stock", Int64.Type}}),
    UnpivotOSC = Table.Unpivot(Type, {"Product A In", "Product A Out"}, "Attribute", "Value"),
    Pivot = Table.Pivot(UnpivotOSC, List.Distinct(UnpivotOSC[#"Type of movement"]), "Type of movement", "Value"),
    Reorder = Table.ReorderColumns(Pivot,{"Date", "Attribute", "A", "B", "C", "Unit Cost", "Unit Cost2", "Client", "Selling Price", "Product A in Stock"}),
    Sort = Table.Sort(Reorder,{{"Date", Order.Descending}})
in
    Sort[/SIZE]

Woah, I'm sorry but I'm new to Power Query. How would I go about using those formulas or that information there? So far i've played with the options in the menu to split cells, re-arrange the order of cells, etc.

be sure the name of source table is the same as in the M-code (here: Table1)
copy code from the post
open Advanced Editor
paste code

here is source table I used

Date	Type of movement	Product A In	Product A Out	Unit Cost	Unit Cost2	Client	Selling Price	Product A in Stock
11/10/2019​	A	20​		3​				100​
03/10/2019​	B		10​		2​	Client A	25​	85​
23/09/2019​	C	5​		2​				90​
22/09/2019​	B		9​		5​	Client B	20​	91​
15/09/2019​	A	30​		4​				70​
13/09/2019​	B		12​		4​	Client D	18​	35​
10/09/2019​	A	7​		5​				100​
02/09/2019​	C		8​		3​	Client A	25​	12​
24/08/2019​	A	10​		9​				13​

there is NO $ sign in Selling Price column

dates looks different because you are in US style, me not

It worked, thank you! I'll need to look into learning how to write code like that.

 

[heretolearnexcel]

Does anyone have any suggestions regarding the information I want to do with my pivot table?

You are welcome

I used PQ ribbon for everything, nothing manual
