Tier2 Submit Software

Significant Changes in Tier2 Submit 2019

  • Resolved a bug in which users could not export data if an attachment had special characters in the file name (rev. 3).
  • Addressed requests from users to show the list of imported facilities directly after import (rev. 3).
  • Resolved a bug that prevented importing if the files were imported as a group and two or more of them shared a contact with the same record ID, but had different information (rev. 3).
  • Added an option to expand or collapse the list of chemicals and contacts on a facility page, if the list contained over 20 chemicals or contacts (rev. 3).
  • Added the ability to copy, cut, and paste using highlight and right click (rev. 3).
  • Updated EHS rules for facilities in Vermont in order to accommodate special EHS rules in Vermont (rev. 3).
  • Resolved a Macintosh-only bug in which users saw an alert to update to rev. 2 when they were already using rev. 2 (rev. 3). 
  • Resolved several bugs related to horizontal and vertical scrolling (rev. 2).
  • Updated validation rules for Massachusetts facilities to only require chemical state fields when a chemical is marked as an EHS, and only require a chemical carrier for facilities that have at least one EHS (rev. 2).
  • Resolved a bug that appeared when deleting the only facility associated with a contact (rev. 2).
  • Fixed a bug in which deleting and re-adding an attachment showed an incorrect error message (rev. 2).
  • Improved the PDF output to no longer cut off the signature box at the bottom of a page, and to give more space for longer names and titles (rev. 2).
  • Made cosmetic adjustments to state fields for Colorado, Oklahoma, and Ohio. These changes do not impact the validation rules or requirements on any fields (rev. 2).
  • Provided a new, smarter warning message when changing the state of a facility that already has data entered in its state fields (rev. 2).
  • Redesigned interface completely for a smoother user experience.
  • Added real-time validation that catches validation errors as users type them, and reports the validation status of a record at any moment.
  • Added a map view of latitude and longitude coordinates.
  • Added ability to export and import in sets of .csv files.
  • Updated state-specific fields.
  • Revised helps.
