Filter the cases of the log which violates the four eyes principle on the provided activities.

  • log – event log

  • activity1 (str) – first activity

  • activity2 (str) – second activity

  • activity_key (str) – attribute to be used for the activity

  • timestamp_key (str) – attribute to be used for the timestamp

  • case_id_key (str) – attribute to be used as case identifier

  • resource_key (str) – attribute to be used as resource

Return type:

Union[EventLog, pd.DataFrame]
