National Data Warehouse (NDW)

Verifying Your Data

Verifying Data Received by the NDW

When a file is successfully received by the NDW, the process sends out an automated email report called the NDW Data Transmission Log Report (commonly called the “Acknowledgement Report”, or “ACK” for short ) to the Site/Area contacts we have in our contact list. Also see the section “Export Tracking Mart” for additional resources for tracking your file’s status.

Below are some commonly asked questions concerning your exports received by the NDW:

Who receives the notifications and how can I change the recipients?
What if the Acknowledgement Report (ACK) indicates errors/rejections?
What if I sent a file but did not receive an automated email Acknowledgement Report/Confirmation?

Verifying Data Loaded by the NDW

When a file is successfully loaded into the NDW, the process sends out an automated email report called the NDW Post Data Load Report to the Site/Area contacts we have in our contact list. Also see the section “Export Tracking Mart” for additional resources for tracking your file’s status.

Below are some commonly asked questions concerning your export files that have been loaded into the NDW:

What if the Post Load Report indicates that exceptions/rejects/transformations have occurred?
Can you explain the errors on the Post Load Report and how to fix them?
How can I identify the encounters or registrations involved?
Why am I missing my Post Load Report?

The most common reasons that these reports are not received when the files actually have been loaded include email problems, contact list errors, and system down-time due to maintenance. It is also possible that there is just a delay in processing. Please allow 24 hours to receive your Post Load Report. If you have access, check the Export Tracker web site for a “loaded date” for the Export ID in question. If you believe you are missing a report, please email support@ihs.gov and we will review the situation and respond accordingly.
