error code in dax

Hi all,

we have installed a lot of IoT devices in US and EU, I would like to check if
minimum voltage of devices installed in US insider range: 5V -12V
minimum voltage of devices installed in EU insider range: 5V -9V

if above condition satisfied, then notification should return value 1,

the table visual as result will be like following:

IoT device ID	Min Voltage	Region	notification
1122	11	EU	0
1133	8	EU	1
1145	15	US	0
1155	11	US	1

I have following code

MinVoltageN =

VAR _minV=min(datatable[VOLTAGE])

VAR _showminvoltage =

SWITCH( TRUE(),

VALUES(TRACKSHEET[REGION])="EU"&&_minV<9&&_minV>5,1,

VALUES(TRACKSHEET[REGION])="US"&&_minV<12&&_minV>5,1,

BLANK()

)

-- Notification

VAR _Notificationminvol =

if (_showminvoltage, 1,0)

RETURN

I got following Error Message:
MdxScript(Model) (127, 1) Calculation error in measure 'Notification'[MinVoltageN]: A table of multiple values was supplied where a single value was expected.

appreciate your help and comment!

Thanks in advance!

Try

MinVoltageN = IF ( ISINSCOPE ( TRACKSHEET[REGION] ), VAR _minV = MIN ( datatable[VOLTAGE] ) VAR _showminvoltage = SWITCH ( TRUE (), VALUES ( TRACKSHEET[REGION] ) = "EU" && _minV < 9 && _minV > 5, 1, VALUES ( TRACKSHEET[REGION] ) = "US" && _minV < 12 && _minV > 5, 1, BLANK () ) -- Notification VAR _Notificationminvol = IF ( _showminvoltage, 1, 0 ) RETURN _Notificationminvol )

Thanks, It works.

could you help me to understand what could be the problem behid my code?

Thanks in advance!

My guess is that the problem was triggered in the total line of a table or matrix value. If the region wasn't filtered down to a single value, as would be the case for a total, then VALUES will return all the regions as a table, and you can't compare a table with multiple rows with a scalar value. By checking ISINSCOPE you are guaranteeing that there will be only 1 value returned and so you can compare that to a scalar value.
