Details of any adjustments/credits should be included in the billing report
Currently the only way to view the credit/adjustment amount is via the EA portal in the reports tab and even that does not provide a proper breakdown of the amount or any clarity on what the credit is for and for which subscription it is applicable.
Any credits/adjustments received from Microsoft should be included in the billing report, which can also be pulled down using the consumption API.
A few additional rows in the CSV report indicating credit in the "Cost" or "ExtendedCost" column would make this more transparent.
Thanks for the feedback. Let us know how important this is to you by voting it up.
