How to handle NULL value in custom column

[Anonymous]

HI,

I need to to convert the below expression to power BI supported expression when I am going to add new column :

if(not isNULL(DOC_RECORD_KEY), DOC_RECORD_KEY,
if(not isNULL(MSG_RECORD_KEY), MSG_RECORD_KEY, GATEWAY_RECORD_KEY)
) as TRANSACTION_RECORD_KEY

Can anyone tell me the correct syntax for it?

Hi,

I am using the below code:

if ([DOC_RECORD_KEY] <> "NULL", [DOC_RECORD_KEY],
if([DOC_RECORD_KEY] <> "NULL", [DOC_RECORD_KEY], [GATEWAY_RECORD_KEY]
)
)

but getting 'Token RightParen Expected' error. So please correct me in this case.

Hi @Anonymous

You may refer to below DAX.  If it is not your case, please share your data sample and expected output.

Column =
IF (
    Table[DOC_RECORD_KEY] <> BLANK (),
    Table[DOC_RECORD_KEY],
    Table[GATEWAY_RECORD_KEY]
)

Hi,

I am using the below DAX expression:

TRANSACTION_RECORD_KEY = if([DOC_RECORD_KEY] <> BLANK(),[DOC_RECORD_KEY], if([MSG_RECORD_KEY] <> BLANK(), [MSG_RECORD_KEY], [GATEWAY_RECORD_KEY]))

but getting the below error:

Argument '3' in IF function is required.

Please correct the above syntax.

Hi @Anonymous

I've tested your DAX expression with my data. It seems nothing wrong with it. It's better you can share your data sample or show the error screenshot.

Column = IF([DOC_RECORD_KEY]<>BLANK(),[DOC_RECORD_KEY],IF([MSG_RECORD_KEY]<>BLANK(),[MSG_RECORD_KEY],[GATEWAY_RECORD_KEY]))
