Create a table composed of the last x rows of 3 other tables

[boddydan]

Hi everyone,

I'm looking to create a table which is made up of the last few (e.g. 1000) rows of several other similar tables (all with the same column names), and was wondering if anyone knew how to do this as I'm very inexperienced in Power BI.

As an extra requirement I'd also like to add an extra column to my formed table which could be called 'Reference', and each line of this column would have the table name that the corresponding line came from. E.g. 

Reference

Table1

Table1

Table1

Table2

Table3

This reference column would exist so that I could perform filtering and and only show data on some visuals from specific tables.

If anybody could provide any insight on how to achieve this I'd greatly appreciate it.

Many thanks.

Hi @boddydan ,

Before you create the table from other similar tables, add a custom column and call it as Reference. And you can indicate the reference you need. Then create the table.

Hope this helps.

Hi @boddydan ,

Please check if this is what you want:

let
    FilterTable1 = Table.AddColumn(Table.LastN(#"Table1",2),"Reference",each "Table1"),
    FilterTable2 = Table.AddColumn(Table.LastN(#"Table2",2),"Reference",each "Table2"),
    FilterTable3 = Table.AddColumn(Table.LastN(#"Table3",2),"Reference",each "Table3"),
    Source = Table.Combine({FilterTable1, FilterTable2, FilterTable3})
in
    Source

Best Regards,
