    Hi Anonymous 

     

    Try the below if it works for you 

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUUpMLsksSwUyjJRidaKBJJKQIVjIGFnIDCxkgilkiixkDhYyA7I8/RydQzzDXIFMC7CgOaqgJVjQAsVWA7CYJRYxIIUmGAsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [#"EMPOLYEE ID" = _t, STATUS = _t, MANAGER = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"EMPOLYEE ID", Int64.Type}, {"STATUS", type text}, {"MANAGER", Int64.Type}}),
    #"Next Line Up Menager" = 
        let 
            #"Filtered Rows" = Table.SelectRows(#"Changed Type", each ([STATUS] = "INACTIVE")),
            #"Merged Queries" = Table.NestedJoin(#"Changed Type", {"MANAGER"}, #"Filtered Rows", {"EMPOLYEE ID"}, "Changed Type", JoinKind.LeftOuter)
        in
            #"Merged Queries",
    #"Expanded Changed Type" = Table.ExpandTableColumn(#"Next Line Up Menager", "Changed Type", {"MANAGER"}, {"Next Line Up Menager"})
in
    #"Expanded Changed Type"

    Hi and thank you Mariusz.

     

    Can you please expand a little bit on the propsed solution, from the code you pasted, I was trying to understnad where the actual "magic" happens, is it here?

     

    Next Line Up Menager" = 
        let 
            #"Filtered Rows" = Table.SelectRows(#"Changed Type", each ([STATUS] = "INACTIVE")),
            #"Merged Queries" = Table.NestedJoin(#"Changed Type", {"MANAGER"}, #"Filtered Rows", {"EMPOLYEE ID"}, "Changed Type", JoinKind.LeftOuter)
        in
            #"Merged Queries",
    #"Expanded Changed Type" = Table.ExpandTableColumn(#"Next Line Up Menager", "Changed Type", {"MANAGER"}, {"Next Line Up Menager"})
in
    #"Expanded Changed Type"

     

     Are you performing a merge within the same query?

      Hi Anonymous

      In PBI it is possible to encapsulate a section of code withing "let-in" group. In most cases it just makes the query look tidier in the editor.

      In the code you have cited the bit relating to creating (filtering) a table that contains inactive employees and then merging it to the original table.

      It is possible to re-write it to:
      #"Filtered Rows" = Table.SelectRows(#"Changed Type", each ([STATUS] = "INACTIVE")),
      #"Merged Queries" = Table.NestedJoin(#"Changed Type", {"MANAGER"}, #"Filtered Rows", {"EMPOLYEE ID"}, "Changed Type", JoinKind.LeftOuter),
      #"Expanded Changed Type" = Table.ExpandTableColumn(#"Merged Queries", "Changed Type", {"MANAGER"}, {"Next Line Up Menager"})
      in #"Expanded Changed Type"

      Kind regards,
      JB

        Thank you Anonymous , very clear.

        I guess I now need one last "bit" of help with the code.

         

        I have to adapt the "Table from Rows" to my current query, therefore the M code will have to be different.

        I looked up the syntax of the function "Table.fromRows", but I cannot figure out how to tell PBI to select my entire current table and create the "sub-" table where the "Next Line Up Manager" data are created.

         

        This section of the code below, is recreating the sample I have put in my first post, but I now need to use my real data.

        Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUUpMLsksSwUyjJRidaKBJJKQIVjIGFnIDCxkgilkiixkDhYyA7I8/RydQzzDXIFMC7CgOaqgJVjQAsVWA7CYJRYxIIUmGAsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [#"EMPOLYEE ID" = _t, STATUS = _t, MANAGER = _t])

         

        Thanks!

    Hi Mariusz , I understand your solution and accept it, only question is, how do in change this code:

     Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUUpMLsksSwUyjJRidaKBJJKQIVjIGFnIDCxkgilkiixkDhYyA7I8/RydQzzDXIFMC7CgOaqgJVjQAsVWA7CYJRYxIIUmGAsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text

    to capture my actual data? 

    I suppose that  "BinaryFromText" was generated somehow, right?

      Hi   

      This is generated when you use the "Enter Data" functionality you don't need to worry about this bit.

      All you need to do is a few extra steps in your table.

      1. filter your table to All Inactive

      2. Use Merge Queries 

      On Current Table, with join on Manager and Employee ID

       

      3.  Select Merged Queries Step from applied steps, go to the formula bar and replace #"Filtered Rows" with the step before.

       

      4. last step is to expand your tables.

       

      Hope this helps

      Mariusz

        Hello Mariusz 

        thank you so much for the clear help.

        This key piece of training is extremely useful

        I will now try your steps, but before I do I have a question,  about step 1: if I filter my table by Inactive before I merge, I have then to unfilter it afterwards , otherwise my final results will be wrong, or is this done in step 3 in your instructions?

         

        thanks a mill!
