Exclude items from a filtered list

[Anonymous]

I have a master table of person's names and I have a separate table of individuals I want to exclude from the master list.

Rather than removing the individuals one by one from the visual/page/report filters, is there another method to this?

Hi  @Anonymous

Two options:

1. Create a calculated table like this:

NewMasterTable =
CALCULATETABLE (
    MasterTable,
    EXCEPT ( DISTINCT ( MasterTable[Name] ), ListToExclude )
)

and use it as new master table. 'ListToExclude' is the one-column table with the names to be excluded. 

2. a) Create a one-column table with the list of names to keep:

FilterColumn =
EXCEPT ( DISTINCT ( MasterTable[Name] ), ListToExclude )

b) Place FilterColumn[Name] in Page level filters and select Advanced Filtering --> Show items when the value is:  Not blank

Looks like EXCEPT only works if the 2 tables (MasterTable & ListToExclude) have the same dimensions.

My MasterTable has 20+ columns with all sorts of information, and List ToExclude is 1 column.  Is there an approach using Parameters?

The  two tables in the EXCEPT in the code above are one-column tables:

     EXCEPT ( DISTINCT ( MasterTable[Name] ), ListToExclude )

The number of columns in MasterTable is irrelevant.

This is the error I am having:

A single value for column 'name' in table 'MasterTable' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result.

Neither of the options suggested above are measures. They're both calculated tables as indicated

Found 2 methods doing so:

1) Except(SelectColumns(MasterTable, "XXX", MasterTabl[Name]), SelectColumns(ListToExclude, "YYY", ListToExclude[Name]))

2) Anti Join using merge queries

thanks!
