want to pick up data with relative date range(past * days)

Hello:

during pre-filter step, i only want to get the new dataset with limited data. so it should be updated autolly on daily basis.

I tried below formula but it is not workable.

( diff(val(now()),val('work_order_created_date')) >= 10 )

Please help me to get the right methods.

Thank you veyr much.

Hi, 

The challenge you describe is solved using the partitions functionality, which allows you to process a subset of data from a relative time range (see attached image).

My suggestions is that you start by completing this academy course on the subject, https://academy.dataiku.com/advanced-partitioning.

I hope this helps.

Best regards

Hi,

That is because your dataset is not partitioned yet. Please complete the academy course that I indicated to first learn the concepts and understand how to use it.

Best regards
