Questions



Is there a drop-dead deadline?



What types of reports will be available from the Accounting Portal? Is there a programmatic way to retrieve data? This is crucial for our verification module.



It looks like an acknowledgment is performed indicating the success/failure of the communication between the client and consumer. Does this acknowledgment indicate the result at the message level or does this extend to the APEL database update the consumer is performing?



How are failures handled? Is it possible to set timeouts and retries?



Is an update an atomic operation (like database commit)?



Currently we reload monthly results daily. How would you propose handling corrections? Can there be a message format that would allow for removing based

• n site and year/month? This would simplify processing on our end.



When does the data become available from the Accounting Portal (what is the time delay between sending and reporting)?



It appears that the test environment is limited to just the messaging and database

• update. Will there be an environment which tests the complete data flow inclusive
• f the EGI portal UI?

Integration Plans

 Start working sometime in October  Could take a couple of months to make a transition  Programmatic retrieval of information is essential for

us

 The ability to drop and resend data for the current

month will help to minimize manual work when data correction is needed.

 Good communication is crucial for success of this

transition!
