maximum Date

[guthikv]

Hello all,

Hope you can help me on this.

Currently I have list with around 10 columns. Of these 3 columns are critical that includes Order Number, Notes, Last Updated Date.
For every order there might be multiple notes updated and correspodingly a last Updated Date is recorded.

I would like to grab the last updated date and notes of every order number.

Please suggest what would be the best way to it.

Thanks in advance.

Drag a data item and write an expression Max([Your Date]) ,I think that be it! Thanks

A max([Date]) will be used within the context of other item brought in from the query, which, in case you bring in the note will yield all records, not the last one.

You will need a filter like [date] = max([date] for [ordernumber]) or something similar with after auto aggregate setting

It's also worth mentioning that the correct way to solve it is by modifying the table and the loading process to make it into a SCD Type 6. That way you can index on the flag field. The other ways would require more IOs on the table.
