Selecting attributes to replace during deployment
When you create a package definition, you can
specify the attributes that must be replaced with appropriate values
at deployment time. Attributes must be replaced, for example, when
the data constraints in the target environment do not match the data
constraints in the source environment.
About this task
The attributes to be replaced are stored in the metadata of a package. The replacement values are determined by the replacement rules that are defined in the target environment.
