is it possible to check a date by two or more events for a subject which is currently being processed.
For example, we have a lot of subjects and three events for each subject: Screening, Baseline, Visit1.
On Visit1 we will take a date of biopsy.
The test would be: The date of biopsy for subject no.15 (currently filled out) must be greater as the visit date of Baseline and the visit date of Screening for the same subject.
The rule will find the right subject on Screening or Baseline event that matches the subject on Visit1 by itself or must we have to add the subject ID field to the rule?
Thanks for help,
