Can we reference a prior run of a DQ Job when writing a rule?

Question

I know we can reference datasets in a custom rule but a customer has asked whether than can refer to a specified prior run of a job against that dataset for a rule. For example a rule that checks the row count of the current run against the row count of a specific prior run.

Getting historical state of the same dataset Syntax: @t , where n parameter means, how many days should we go back in the past at the base dataset (marked with @<dataset_name>) Example:

@t1 , will point to the data which was used at yesterday’s run
@t4 , will point to the data which was used 4 days ago
