Hello @Anonymous,

i recommend that you create a bridge table so that you can establish a "1 to n" and an "n to 1" relationship between your tables.

Code Query BrideTableGLAccountNo:

let
    BudgetGL = Table.SelectColumns(#"Budget GL", {"G_L_Account_No"}),
    Actuals = Table.SelectColumns(#"Actuals XXX", {"G_L_Account_No"}),
    Combined = Table.Combine({BudgetGL, Actuals}),
    RemovedDuplicates = Table.Distinct(Combined)
in
    RemovedDuplicates

Hi,

Thanks for the solution @ManuelBolz  provided, and i want to offer some more information for user to refer to.

hello @Anonymous , as @ManuelBolz  mentioned, you can create a new table as a brigdge table, you can also use calculated table. you can refer to the following solution.

Sample data is the same as you provided.

Create a new table

Bridge = DISTINCT(UNION(VALUES('Budget GL'[G_L_Account]),VALUES(Actual[G_L_Account])))

Then create relationships amont the tables

And you can refer to the following link.
