Administrative Web Interface (AWI)

The Administrative Web Interface (AWI) provides Ohio State faculty and staff a way to view charges related to services requested from OTDI – whether for one month or a span of multiple months – in PDF and Excel format.

Effective 2/1/24, OTDI is generating Workday Supplier Invoices per the university's Internal Order Billing (IOB) process on the first business day of each month.

  • Notes regarding standard Workday functionality with Internal Supplier Invoices:
    • Invoices with lines equal to or greater than $3,000.00 will require approval.
      • Please do not send back or deny these invoices. We cannot generate new or modified statements, so it's best to utilize Accounting Adjustments for worktag changes.
      • Please approve in a timely manner.
    • Invoices cannot be posted to a prior month.
      • We are unable to accommodate any requests to retroactively post invoices to a prior month.
    • Billing charges are now one month in arrears.
      • As an example, February charges will be on invoices for March 1, and will be posted in March.
    • Nothing has changed regarding our AWI.
      • AWI is still your main source of information for all the details behind any OTDI billing charge appearing in Workday.
  • Updating departmental worktags for future charges or any other inquiries regarding charges/credits can still be directed to otdibilling@osu.edu.
  • Billing charges from the OTDI prior to this change are in Workday under the journal source “OTDI Billing Charges.”
