You can call instances that are already defined in the repository. You can call Data Elements (in the Pacbase facet), Data (in the COBOL facet), or Meta Data Aggregates in a Meta Entity, Meta Entity Type or Meta Data Aggregate. You must indicate a cardinality and specify whether the allowed values must be controlled for the Data Elements or Data.
The value of the Maximum cardinality field must be higher than the value of the Minimum cardinality field. If it is not, an error will be displayed in the User Entity.
