ISEMPTY function returning FALSE although no matching records in table

[giramswa]

Hi All,

I wrote below measure to be able to display only current users records in the dashboard:

LoggedInUserIsPm =

VAR CurrentUser = USERPRINCIPALNAME()

VAR LoggedInUserEmail =
DISTINCT(SELECTCOLUMNS(
FILTER(PM_Table, PM_Table[EMPLOYEE_USER_PRINCIPAL_NAME] = CurrentUser), "EMPLOYEE_E_MAIL", [EMPLOYEE_E_MAIL]))

VAR IsPm = ISEMPTY(CALCULATETABLE(ReportTable, ReportTable[project_manager_email] = LoggedInUserEmail ))

VAR countMatchRows = COUNTROWS(CALCULATETABLE(ReportTable, ReportTable[project_manager_mail] = LoggedInUserEmail ))

Return

"Email: " &LoggedInUserEmail&" IsPm? "& IsPm &" CountMatchingRows "& countMatchRows

Outcome - Email: IsPm? False CountMatchingRows 9

There is no matching record in 'PM_Table' for currently logged in user's email address, hence 'LoggedInUserEmail' is blank.
Still ISEMPTY function is returning 'False' and COUNTROWS returning 9 records.

Expected outcome is ISEMPTY should return TRUE. What am I missing here?

do you have any records where the project manager email is blank?

Yes, you are right. After posting this query, I noticed that there are 9 records having blank in project manager email. Which matches the outcome of COUNTROWS function.

I was able to get around this issue by modifying the measure as below:

LoggedInUserIsPm =

VAR CurrentUser = USERPRINCIPALNAME()

VAR LoggedInUserEmail =
DISTINCT(SELECTCOLUMNS(
FILTER(PM_Table, PM_Table[EMPLOYEE_USER_PRINCIPAL_NAME] = CurrentUser), "EMPLOYEE_E_MAIL", [EMPLOYEE_E_MAIL]))

VAR IsPm = IF(ISBLANK(LoggedInUserEmail), 0, NOT(ISEMPTY(CALCULATETABLE(ReportTable, ReportTable[project_manager_email] = LoggedInUserEmail )))

Return
1 * IsPm

Thanks for your inputs.
