Symptoms
There is a difference between the Total Invoiced Amount values shown in CCP and the sum of the billing order for the account. The difference is persistent across months, however, the total sum of reports and orders matches.
Cause
There is a few hours discrepancy between the generated Azure usage reports and the generated orders, resulting in a difference in displayed sums. The Azure CSP application issue is known under internal ID APSA-19302.
Resolution
The issue is permanently addressed in Azure CSP version 5.0:
[Release notes] Azure Cloud Solution Provider Integration 5.0
Important notes:
- Once the hotfix is installed, the proper calculations will appear in the upcoming periods, and the old periods should get fixed (by step 5 in the pre-upgrade steps).
- The fix also corrects billing periods and aligns them between Billing and Azure application. This change produces an impact on the last billing period before the fix. For example, the Azure period had 20th as the start date, but the Billing period started from the 1st day of the month. After the fix is applied, the last period in CCP v2 will be shown as e.g. 01-Jan - 01-Feb, but the usage will be shown for 20-Jan - 31-Jan. This is the effect of aligning the periods.
