Nested IF Statement Ignoring Blanks
Hi, Im looking for some help creating a new column to distinguish wether an Appointment was Early, Late or In Target. I have 3 fields that are going to be used APPOINTMENT ACTUAL_START_DATE,...
Hi Anonymous
If you're adding this as a calculated column, you don't need all of the MAX functions. They are essentially calculating the max value for that entire column - not what you're after!
I always favour the SWITCH function rather than nested IF statements as I find it easier to read.
Try adding a calculated column with the expression below:
APPTCTGY = SWITCH( TRUE(), ISBLANK( FACT_Appt[APPOINTMENT ACTUAL_START_DATE] ), "EARLY", FACT_Appt[APPOINTMENT ACTUAL_START_DATE] < FACT_Appt[APPOINTMENT_WINDOW_START_DATE ], "EARLY", FACT_Appt[APPOINTMENT ACTUAL_START_DATE] > FACT_Appt[APPOINTMENT_WINDOW_END_DATE], "LATE", FACT_Appt[APPOINTMENT ACTUAL_START_DATE] >= FACT_Appt[APPOINTMENT_WINDOW_START_DATE] && FACT_Appt[APPOINTMENT ACTUAL_START_DATE] <= MAX(FACT_Appt[APPOINTMENT_WINDOW_END_DATE] ), "IN TARGET" )Best regards,

You can use Switch True and use isblank to check for blank
Example
Switch (true(),
condition, action,
condition, action,
condition, action,
else action)
Thanks. What logiv would you use within the switch to ignore the null values in the ACTUAL_APPOINTMENT)START_DATE field.
Thanks

Switch( true(),
isblank(APPOINTMENT_ACTUAL_START_DATE ), "Early",
....
)
