Understand specification alias

When you select a specification through the specification browser in the Object Editor, an alias is automatically assigned to the selected specification and it appears in the Object Editor. For most of the cases, an alias is equal to the SpecID in the MES database. The alias name must conform to the System Platform naming conventions that are used for User Defined Attributes (UDAs).

The MES database allows certain characters such as single quote and space for the SpecId property of a specification, which are not supported in System Platform attribute names. To overcome this problem, an alias is created for the selected specification.

The Alias is then used in the name of attributes to organize all specification related properties, such as Specs.<SpecAlias>.SpecId, Specs.<SpecAlias>.SpecGroupId, Specs.<SpecAlias>.Units.
