Including or excluding rows

Anonymous - For the simplest cases, filter vs slicer is merely a matter of preference. Some thoughts:

Arguments for Filters:

1. Filter Pane can used as the "one-stop-shop" to check the current scope.  

2. Filters can be applied to a visual, page, or report in a consistent way.

3. Filters have options for advanced filtering.

4. Filters take up less space (if the filter pane is showing anyway)

Arguments for Slicers:

1. Slicer has more flexible formatting.

2. Slicer can be linked across pages with more flexibilty.

3. Slicers give more of a "feeling of being part of the report".

4. Slicer can never be hidden, as the FIlter Pane can. Therefore, the scope is not hidden.

How it would work:

If you are interested in always showing the other values, and sometimes showing admin, try the following:

1. Add a Disconnected Parameters table, like this (I included one other parameter to show how you can combine multiple parameters into this table.):

Parameters = 
var budg_act = DATATABLE("Budget vs Actuals Display",STRING,{{"Actuals Only"},{"Both"},{"Budget Only"}})
var inc_admin = DATATABLE("Include Admin",STRING,{{"No"},{"Yes"}})
return CROSSJOIN(budg_act,inc_admin)

2. Add a measure like the following:

Hours Measure = 
var _inclusive = IF(
    HASONEVALUE(Parameters[Include Admin]),
    IF(
        VALUES(Parameters[Include Admin]) = "Yes", 
        "Inclusive",
        "Exclusive"
    ),
    "Inclusive"
)
return 
CALCULATE(
    SUM(TASKTABLE[Hours]),
    FILTER(
        'TASKTABLE',
        OR(
            _inclusive = "Inclusive",
            [Task] <> "Admin"
        )
    )
)

3. Add a filter or slicer based on "Include Admin" column.

4. Add a filter to your visual based on "Included Row" measure (>0).

I hope this helps. If it does, please Mark as a solution.
I also appreciate Kudos.
