Need DAX from PostgreSql query

[SaiyedAlam]

Hi, This is Alam here, I am sort of new to Power BI and this DAX stuff. Although it is very interesting at the same time i'm getting stuck in certain cases where I am finding any proper resources to solve my problem. I would really appreciate if anyone can help me convert the following PostgreSql query into DAX. The query is:

WITH CurrentWeek AS (

SELECT DISTINCT id, sample_requested_by

FROM designer_activity_dashboard_view

where publish_date >= date_trunc('week', CURRENT_DATE)

AND publish_date < date_trunc('week', CURRENT_DATE) + INTERVAL '7 days'

)

SELECT sample_requested_by, cuv.name , COUNT(*) AS This_Week_TechPack_Published

FROM CurrentWeek

JOIN crm_user_view cuv ON CurrentWeek.sample_requested_by = cuv.id

GROUP BY sample_requested_by, cuv.name

ORDER BY sample_requested_by

 
Would really appreciate your quick response and thanks in advance 

Sincerely 
Alam

Hi @SaiyedAlam ,

You can create a measure as below to get it:

Measure =
VAR _selid =
    SELECTEDVALUE ( 'crm_user_view'[id] )
VAR _selname =
    SELECTEDVALUE ( 'crm_user_view'[name] )
VAR _tab =
    CALCULATETABLE (
        VALUES ( 'designer_activity_dashboard_view'[sample_requested_by] ),
        FILTER (
            'designer_activity_dashboard_view',
            'designer_activity_dashboard_view'[publish_date]
                >= TODAY () - WEEKDAY ( TODAY (), 2 ) + 1
                && 'designer_activity_dashboard_view'[publish_date]
                    <= TODAY ()
                        + ( 7 - WEEKDAY ( TODAY (), 2 ) )
        )
    )
RETURN
    CALCULATE (
        COUNT ( 'crm_user_view'[id] ),
        FILTER ( 'crm_user_view', 'crm_user_view'[id] IN _tab )
    )

Then create a table visual with the Fields settings as below screenshot:

If the above one can't help you get the expected result, could you please provide some raw data in the table 'designer_activity_dashboard_view'  and 'crm_user_view' (exclude sensitive data) with Text format and your expected result with backend logic and special examples? It would be helpful to find out the solution.
