Changings to data structure in Power Query

[D3K]

Hello everyone!

Here is the question I can't find an answer for and will be very thankful for any help.

Please see the attached picture.

Now I have a table without structure: in the same column there are different data "warehouse" and list of products stored in that warehouse. 

How to separate it for 2 different columns, where for any product is noticed it's own warehouse? How to make correct database structure?

Any help will be highly appreciated

@D3K in transform data start a new blank query, click advanced editor and paste the following code. it will create the step and the final result is what you are looking for.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCk8sSs3ILy1OVTBU0lEyMgUScCGlWJ1opWDvULCUCRAHFOWnlCaXFMMljICC5tgkjHHpAAkaYZMA2WyBLoFwHUiPkRlO1xnich2GkTDXGWJ1Bch5pricZ4DbeSATjS1wOs8Ip/uMcbnPDJfzsBplihERsQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"WH/SKU" = _t, Stocks = _t, Status = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"WH/SKU", type text}, {"Stocks", Int64.Type}, {"Status", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "WH", each if [Status] = "Warehouse" then "Warehouse" else null, type text),
    #"Filled Down" = Table.FillDown(#"Added Custom",{"WH"}),
    #"Filtered Rows" = Table.SelectRows(#"Filled Down", each ([Status] = "Products")),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Status"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"WH/SKU", "SKU"}})
in
    #"Renamed Columns"

@parry2k  I've tried to use you algorithm with a few warehouses and unfortunately it doesn't work.

As you can see, we need to fill the column with warehouses not just with the sentence "Warehouse", but with the particular warehouse address (WH 1, WH 2 and so on in the sample above), where particular SKU is stored at.

Can you update your code, please?

Thank you

Hi @D3K ,

Try to modify @parry2k 's query like so:

Here is the complete code:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCk8sSs3ILy1OVTBU0lEyMgUScCGlWJ1opWDvULCUCRAHFOWnlCaXFMMljICC5tgkjHHpAAkaYZMA2WyBLoFwHUiPkRlO1xnich2GkTDXGWJ1Bch5pricZ4DbeSATjS1wOs8Ip/uMcbnPDJfzsBplihERsQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"WH/SKU" = _t, Stocks = _t, Status = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"WH/SKU", type text}, {"Stocks", Int64.Type}, {"Status", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "WH", each if [Status] = "Warehouse" then [#"WH/SKU"] else null, type text),
    #"Filled Down" = Table.FillDown(#"Added Custom",{"WH"}),
    #"Filtered Rows" = Table.SelectRows(#"Filled Down", each ([Status] = "Products")),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Status"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"WH/SKU", "Product"}}),
    #"Reordered Columns" = Table.ReorderColumns(#"Renamed Columns",{"WH", "Product", "Stocks"})
in
    #"Reordered Columns"

Thanks a lot! It works. The problem was in the right way of sorting Status column, cause it was filling down incorrectly, if breaking the default sorting.
