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
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!
Solved! Go to Solution.
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
)
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.
thank you very much
