No problem Matt. On step 4 of the connector configuration you can choose whether you want to do an overwrite or an append of the data to an existing dataset in Apptio. Apptio can support monthly time filtering/versioning of data in two ways: 1) append each month of extracted data into the beginning of the fiscal year and then use our dataset date filtering functionality to parse the data into the correct month 2) or load (overwrite) the data into each specific time period in Apptio. For option #2, you could choose to load tickets data on a weekly basis from Remedy but you would want to pull all of the tickets month-to-date and do an overwrite of the monthly dataset in Apptio.
Yes, the create date and modifed date are equal for new tickets that get created in Remedy. I would definitely like to hear any feedback you have on additional filter criteria that would be useful from the DataLink standpoint as we haven't added them because we have such rich transform/filter functionality once the data is loaded and aren't typcially worried about data volumes when it comes tickets data. Let me know though what use cases your are thinking of from a filtering standpoint.
Cheers,
Greg
