About Parameters
In Oracle LSH you must create a defined object called a Parameter for each input and output parameter in a Program's source code.
In Workflows and Report Sets you can define Parameters especially for the purpose of passing their value (to be set in the Execution Setup definition or at runtime) to other Parameters you specify within the Workflow or Report Set, reducing the number of Parameters to be set at runtime. You can also pass the value of an output Parameter of one Program in a Workflow or Report Set to the input value of another Parameter in the same Workflow or Report Set (see "Setting Up Parameter Value Propagation").
Note:
A Load Set, Data Mart, and Business Area contains Parameters defined by adapters used to create these objects. See Setting Load Set Parameters, Setting Data Mart Parameter Values, and Setting Business Area Attributes and Parameters for more details.
A Parameter definition inherits attribute values from its source Variable (notably data type, length, and default value, if any) and has additional attributes such as Required, Visible, and Read Only, and its list of acceptable values, if any.
