Before any alternate or deviation can be created, an attribute must be created on the A.50.01 Attributes screen. This attribute is later used to attach and highlight the description of the alternate or deviation.
When the attribute is created, it must be assigned to the project default ZP_DEVATTR on the MSCM tab of the A.20.12 Project Defaults screen.
Once this assignment is made, the attribute can be used in various places to created alternates and deviations.
