Create N tables with a function Power Query M

[Anonymous]

Hi all, 

I have a list of list like this:

Each list is composed by a table and a string, like this:

I want to write an M function that, for each list of the first photo, create a new table in the data model and give her name like the string in the list. For example, with the list above i want to create the new table with name "AZIENDA_GERARCHIA_010". I loop on each list with this code that is working fine:

    Output = List.Transform(ListOfTables , each createTable(_))

The code of my createTable function is:

createTable = (l as list) => (
    let
        tableHierarchy = l{0},
        nameTableHierarchy = l{1},
        newTable = Table.FromRecords(Table.ToRecords(tableHierarchy))
    in

        newTable

)

But when i call createTable function, it create a new Source in the scope of the script! Not in my Data Model on Power Bi!

Instead, if i call createTable from button "Invoke", it creates a new table in the Data Model for each time i press on "Invoke".

My questions are: 

1. How can i create a new table in the Data Model?
2. How can i rename the table dinamically with the name i want to give her?

Hello @Anonymous 

I think there is no possibility to create with one query more tables, because one query can only have one result in form of a table. Also there is no possibility to change the query name within M

All the best

if you gave us some details of the situation you have to manage, we could look for some workaround, like this where you have a list of tables and you can refer to them by name through the key field of a record.

[although, I'm sure, it's a solution you could very well come up with on your own]

let
    manyTabs = List.Transform({1..9}, each Table.FromValue(_)),
    manyNames=List.Transform({"1".."9"}, each "tab"&_)
in
    Record.FromList(manyTabs,manyNames)

@Anonymous  I don't understand the solution, can you show me the content of the table tabs?

I don't know if this is a solution of your problem.

It is only a record having a list of key and as correnspondent values a list of tables.

@Jimmy801 ok but why when i call the same function with the button invoke it creates a new table?

just a guess, 

may be this

Function.Invoke(function as function, args as list) as any 

could makes what you want
