    A selector function is a PL/SQL procedure that automatically identifies the specific process definition to execute when a workflow is initiated for a
    particular item type but no process name is provided. Oracle Workflow also supports using a callback function to reset or test item type context information. You can define one PL/SQL procedure that includes both selector and callback functionality by following a standard API.
    Oracle Workflow can call the selector/callback function with the following commands:

    RUN - to select the appropriate process to start when a process is not mentioned.

    SET_CTX - to establish any context information for an item type and item key
    combination that a function activity in the item type needs in order to execute.

    TEST_CTX - to determine if the current item type context information is correct
    before executing a function, such as during background processing.

    Please check the Workflow Dev Guide for more information on the Standard API for a Selector Function.

    Thanks,
    Dilbagh
