Overview:
Between 6:23 AM to 7:40 AM MST (1 hour 17 minutes) on 5/5/2021, 4 of the Enterprise systems were asking the user to select a database system when logging into SAP, but no databases were listed, preventing a successful login.
Cause of the issue:
A misconfiguration in the sign-in process on these servers happened while setting up the new configurations to prepare for the upcoming SAP 10 upgrades.
Resolution:
The configuration was corrected, and additional training has been done for the team to learn the nuances of these 4 systems with this issue to avoid the configuration mistake in the future.
After the SAP 10 upgrade, this particular configuration option is standardized, so the risk on the higher version goes away.
