User name issue

Situation:

We have a problem with a user in Adeptia. For some reason its not appearing when we move mappings from dev to prod environment only for one user.

Basically mappings done by this user have no name when they are moved to prod

Cause:

The user being created in dev and prod independently, therefore the mappings from dev under that user wouldn't be assigned to the "same" user in production when migrated.

Solution:

Delete the user name in production and promote it again from dev to prod environment
