I'm having issue trying to generate a Prior Year to Date calculation based on the max of our billing date 1 year prior . We cannot use Current Date function since my dataset is not truly 'LIVE'…here is what I have so far:
IFNULL(
CASE
WHEN YEAR(CALDAYFORMAT
) = YEAR(DATE_ADD(CALDAYFORMAT
, INTERVAL -1 YEAR))
AND RIGHT( Calday
,4 ) <= RIGHT( MAX( Calday
) )
AND Customer Group A
= '5D'
THEN sum( Invoiced Sales LC
)
ELSE 0
END,
0
)
Calday field is text in 'YYYYMMDD' day format and CALDAYFORMAT is a traditional date
Help please!!!
