after upgrading from Sugar 6.5.16 Professional (Build 1082) to Sugar Professional 188.8.131.52 (Build 1552) in a test environment we have established that the value in field "assigned to" no longer comes from the modul "users" (field "User Name" => this will be what the user logs in to Sugar with on the login page / For example: robin.hood) but rather from the modul "employees" (field "name" => this is composed of first name and given name / For example: Robin Hood)
The big problem is now, that we have linked different connections and queries with other systems over the field "assigned to". All these are no longer working after the upgrade.
Sugar 6.5.16: field value "assigned to" = robin.hood
Sugar 184.108.40.206: field value "assigned to" = Robin Hood
How can we fix that?
Thank you for your help in advance.
