How to add values xx, yy from Column A as new values in Column C and Column D

[msoehnchen]

HI everyone,

i'm kinda stuck. Just to let u know, i'm fairly new to Power Query. I want to add new columns (in pic.2 its "CT1" and "CT3") which contains the values of Colum "Counted Qty" from all following records with the same value in Column "Location". I cant get it to work. Tried searching and googling but couldnt find a solution. I guess that can be achieved in M-Code, but i really cant work it out.

Would be very nice if someone could give me a hint (or even a solution)... 

Originalresult ?

Sample Data:

Date	Transaction Time	List ID	Location	SKU	Tag ID	Original Qty	Update Qty	Counted Qty	TempTag

Hi @msoehnchen 

1. Copy the table 1 to get Table 2

2. In Table 2,

    group table by "location"->Split Column by Delimiter->Remove first Columns after the "location"

3. In Table1

   Add Index->

  Grouped Rows by location, meanwhile add a minium index column based on each group->

  Expand AllRows->

  Filtered Rows where minium index column=index column->

  Merged Queries for Table1 and Table 2 based on "location"->

  Expand Table

Thanks Maggie,
i tried it yesterday by myself and i also came to the conclusion, that only a merge of that table with itself could help. My fault was, that i tried to achieve this whole thing in one query. But this way, i learned a lot 🙂

I did it slightly different than your solution, but i will try your way the next time. I also appreciate the links - very helpful.
