Failed to create a session; confirm that the user has the proper privileges to log on to Microsoft Dynamics

Currently we have a developer working/coding in an active environment where users are currently using the system (non-prod) and had an issue generating good incremental CIL. During this time some of the users started to see the following message

"Failed to create a session; confirm that the user has the proper privileges to log on to Microsoft Dynamics"

In order to resolve this issue try the following

File/Tools/Options/Development/ uncheck the option for "Execute business operations in CIL"

This ended up fixing our issue, but after reading multiple other blogs about AX if this doesn't work then the next step is to run a full CIL. If that doesn't work you should restart the AOS and run the full CIL again.
