This layer of security is intended to validate access to the target procedure step. The application developer implements and validates the logic for access to the DPS and is coded as part of the action language the implements the DPS. The validation logic can be implemented in a common action block or can be external in one or more external action blocks.
The security processing that implements procedure step security can be accomplished by having one of the first few statements of the target Procedure Step call or can use a common or external action block. The called/used action block determines if access to the procedure step is granted. Typically, the called/used action block would import the user ID, transaction code, and other user-defined data that is needed to validate the request. The DPS itself grants access to its own processing using security data that provide by the DPC. The DPC provides this user-defined security data as part of the Import View of the DPS.
