How to get minimum date in the granular level

BootCam — Mon, 01 Aug 2016 15:36:15 GMT

Hi All,

I have a problem Like this:

I have a date field which has all the update date and I have to take the Minimum Date from this field in the granular level.

And i have a status field that has all the Status Code.

Also another field "Processed" that has Boolean value T and F

Now i have to make a field "Active date" in the script based on these three fields.

Logic i am trying use is,

IF(Match([Status],'A','P') and [Processed]='F' and [Update Date]=Min([Update Date]), [Update Date], ' ') as [Active Date]

Seems like my logic is set on the Minimum Date from the Update date not the minimum date from the item/granular level for every products.

How do i write down the code in the script that can work in the Item level? Meaning, getting the minimum date for every product.

Thanks,

Perhaps like this:

SummaryTable:

LOAD

Product,

Min([Update Date]) as [Active Date]

FROM

...source...

WHERE

Match(Status, 'A','P') and Processed = 'F'

GROUP BY

Product

;

Hi Gysbert,

With the Where clause, Am i not limiting my table with the Match(Status, 'A','P') and Processed = 'F' filter?

But my goal is to keep all the data and make a new filed Active date.

Something like that

IF(Match([Status],'A','P') and [Processed]='F' and [Update Date]=Min([Update Date]), [Update Date], ' ') as [Active Date]

I know this piece of code is wrong but the idea is like that.

Thanks,

You can add to your table a min update date, using a group by and left join (bold)

yourtable:

load

product,

status,

processed,

updatedate

.......

left join (yourtable)

load

product,

min(updatedate) as minupdatedate

resident yourtable

group by product; // I think you want the min date by product

then you can do a resident table with an if condition on status, processed, updatedate, minupdatedate to calculate the activedate field
