Using set analysis to get a value of previous period

[etkonwgno]

Hi. I have a dataset with the fields: Account_id, account_score, year_quarter, YearQuarterKey (which is a running sequencial number for every year-quarter combination). I want to use set analysis in a table presentation on my app, and to add the field previous_quarter_score to every row ! in the table, according the field YearQuarterKey

I tried:

=max( {< YearQuarterKey = {"$(=(YearQuarterKey-1))"} >} account_score)

It did not work.

Any thoughts on how to accomplish this?

Thanks

Hi,

You can follow this way.

create 2 variables min & max dates.

=max( {< DateField = {">=$(vMinQtrDate)<=$(vMaxQtrDate)"} >} account_score)

vMinQtrDate = QuarterStart(min(date))

vMaxQtrDate = QuarterEnd(min(date))
