Placing a UDF with Restricted Parameters
When placing a UDF that contains a feature with feature-level or Annotation Element level table-restricted parameters, the restriction definitions of the parameter set created in the target model are taken from one of the following:
The restriction definition file of the target model
The external definition file
The UDF
If model-level relations exist in the UDF, the parameters involved in these relations are created in the target model. If some of these parameters belong to a table-restricted parameter set in the source model, then you must create the entire parameter set in the target model. A conflict preventing the creation of parameters within the parameter set may result from any of the following conditions:
Parameters with the same name exist in the target model
Parameters are not restricted
Parameters have their own restriction definitions.
In such cases only the parameters involved in the model-level relations are created as non-restricted parameters.
