# Introducing the Overview tab for 999 acknowledgments in the Stedi portal

> Stedi's Transactions page now has an Overview tab for 999 acknowledgments. It shows which transaction sets Stedi accepted, which it rejected, and why.

Product: Claims

You can now review 999 Implementation Acknowledgments in a new **Overview** tab on the Stedi portal's Transactions page. The tab shows which transaction sets Stedi accepted, which it rejected, and why, in a human-readable format.

Previously, with only X12 and JSON tabs, you had to locate the `AK9` and `IK5` segments yourself and look up each error code in the [implementation guide](https://portal.stedi.com/app/guides/view/hipaa/implementation-acknowledgment-x231/01HRF41ES1DVGCA6X1EHSRPFXZ).

The Overview tab for a 999 acknowledgment, showing the functional group and transaction set sections

The **Overview** tab shows:

- The functional group's identifier, control number, and acknowledgment code, plus how many transaction sets Stedi received and how many it accepted.

- A section for each transaction set, with its control number and acknowledgment code.

- For each rejected transaction set, a table of errors listing the X12 address, the error code, and the value that failed validation.

A 999 confirms X12 syntax only. To verify whether the payer accepted your claim, check the [277CA claim acknowledgment](https://www.stedi.com/docs/healthcare/submit-claims-sftp-retrieve-responses#277ca-claim-acknowledgment).
