Add ALL to list of values in a Paginated report parameter

[MohanVanks]

Hello All,

I have added ALL as a row value to one of my parameter in paginated report with below DAX.

EVALUATE
UNION
(
DISTINCT(SELECTCOLUMNS(Projects, "Top_ProjectManager","ALL"))
,
SUMMARIZECOLUMNS(
    Projects[Top_ProjectManager],
    KEEPFILTERS( FILTER( ALL( Projects[Top_ProjectManager] ), NOT( ISBLANK( Projects[Top_ProjectManager] ))))
)
)

In my master dataset now I need to make the query work as

• By default the parameter value should be selected ALL, so  I have made Parameter default values as below.

• when ALL is been selected, the report should view all of the values in that column.
• If any perticual value selected then the report should filter based on that.

The master dataset query i have written as below

    FILTER(VALUES(Projects[Top_ProjectManager]), OR(Projects[Top_ProjectManager] = @ProjectManager,  @ProjectManager = "ALL"))

But in dataset properties Parameters query what should i mention i am unable to understand it.

Can anyone please help me wih this.

Thanks,

Mohan V.
