Filtering data via DAX

Hi all, I have a table and I am trying to identify devices based on the below conditions Failed Device - [OutputVolt < ReferenceVolt] in 'VOLT_MEAS', 'CURR_MEAS', 'FUNC_TEST', 'NON_FUNC' pro...

Need Help

you can create a column

Column = 
VAR _volt=maxx(FILTER('Table','Table'[DeviceSerial]=EARLIER('Table'[DeviceSerial])&&'Table'[ProcessName]="VOLT_MEAS"),'Table'[[Output < Reference]]?])
VAR _curr=maxx(FILTER('Table','Table'[DeviceSerial]=EARLIER('Table'[DeviceSerial])&&'Table'[ProcessName]="CURR_MEAS"),'Table'[[Output < Reference]]?])
VAR _func=maxx(FILTER('Table','Table'[DeviceSerial]=EARLIER('Table'[DeviceSerial])&&'Table'[ProcessName]="FUNC_TEST"),'Table'[[Output < Reference]]?])
VAR _non=maxx(FILTER('Table','Table'[DeviceSerial]=EARLIER('Table'[DeviceSerial])&&'Table'[ProcessName]="NON_FUNC"),'Table'[[Output < Reference]]?])
VAR _config=maxx(FILTER('Table','Table'[DeviceSerial]=EARLIER('Table'[DeviceSerial])&&'Table'[ProcessName]="CONFIG_TEST"),'Table'[TestStatus])
return if(_volt="Yes"&&_curr="Yes"&&_func="Yes"&&_non="Yes"&&_config="Pass","Failed Device",if(_volt="Yes"&&_curr="Yes"&&_func="Yes"&&_non="Yes"&&(_config="Fail"||_config=""),"Did not pass/no record",if(_volt="No"&&_curr="No"&&_func="No"&&_non="No"&&_config="Pass","no issue")))

what do you mean [OutputVolt < ReferenceVolt] in xxx? should match for all the process or any one process?

ryan_mayu: I have updated the DAX according to the logic and managed to get it working. Thank you very much for your inputs 🙂

Yes, that's why I ask you the logic

in means AND or OR, that decides how we write the DAX.

FOR ABC 123, the last value of below record is NO, which means OutputVolt > ReferenceVolt. That does not match your logic.

ABC123

17-02-22 1:15:37.013 AM

FUNC_TEST

Fail

1.56

2.00

for BBS319, the last value of below records are Yes, whch means OutputVolt < ReferenceVolt, does not match your logic as well

BBS319	22-02-22 2:50:44.000 AM	VOLT_MEAS	Pass	2.26	2.00	Yes
BBS319	23-02-22 2:50:44.000 AM	CURR_MEAS	Pass	3.21	2.00	Yes
BBS319	25-02-22 2:50:44.000 AM	FUNC_TEST	Pass	3.45	2.00	Yes

That's why we can only get expected result for the second ID.
