Populate prior weeks data when have zeros

Jack

Hi

I have created a report with 53 weeks data at any point of time. For few weeks i have 0 values .

When we have zero values i need to populate prior weeks data. Can you anyone suggest as how can I update prior weeks data when i have zero data for any week.

"zero values" = no value at all, nothing (not a 0, not a NULL, not a "" ... just nothing)

OBIEE will never generate data which doesn't exist, so you better fix that during ETL to add at least an empty/NULL/zero row at that point.

Or you need to model things to cover this case with the right logic (or use EVALUATE to send a LAG call to the DB and try it in that way ....)

"zero values", NULL, '', 0 are completely different things and technically, logically and mathematically not to be used interchangeably!
