SELECT multiple values from slicer and put it into a search function measure to filter report table

[olufosh]

Grab multiple values from slicer and put it in a search measure to filter report table

I have Two Tables - No Relationship

'Azure_LastLoginDateReport' -  Table, contains Displayname, Email etc of users

'EmailTypeSearch' - Table contains a column [EmailSuffix] which holds search strings such as: @BBC.com, @CNN.com, @Sky.com, @abc.com

I use the slicer 'EmailTypeSearch' [EmailSuffix] to select single values and filter the table report accordingly. 

I use a  measure "Exists" that looks at the selected Value and then filters the table report based on selected value.  - See

Exists = SEARCH(

    SELECTEDVALUE('EmailTypeSearch'[EmailSuffix]),

    SELECTEDVALUE('Azure_LastLoginDateReport'[Email]),

    ,-1)

The issue is: When trying to select multiple values in the slicer to filter the table below, it does not work. 

I have seen the use of ALLSELECTED and IN and also the use of a variable, similar to the image below, but I do not know how to apply it to a Search function., as detailed above

I will be extremely grateful, if you could assist in getting  me pass this stage in my development.

SELECTEDVALUE only works when there is only 1 value. To use multiple strings you could iterate over each one and check for a match. I don't know how well this will do performance-wise but you could try

Exists =
MAXX (
    VALUES ( 'EmailTypeSearch'[EmailSuffix] ),
    SEARCH (
        'EmailTypeSearch'[EmailSuffix],
        SELECTEDVALUE ( 'Azure_LastLoginDateReport'[Email] ),
        ,
        -1
    )
)

Hi @johnt75  - Thank you so much. That worked as expected. I am only dealing with circa 10k records, therefore it should be fine performance wise.  Many thanks. 

For ALL - I am also be interetsed how this script can be adapted to use a variable, but only if feasible and possible as I can see cases where this may be needed. for example where a search and sub-search is required
