Peoplesoft Application Engine: Application Library

 Most Application Engine programs are defined to be executable. An executable program has a main entry point in its definition: the Section MAIN. This defines the entry point so whatever method we choose to invoke the program, such as command line or Process Scheduler, can initiate the program. However, in some cases, we may want a program to only contain a collection, or "library," of common routines (in the form of "callable" Sections) that we do not want to run as a standalone program. When sections are defined as "Public," other programs can call the Sections, or routines, that exist in the "library" at runtime. Because this type of Program is not designed to run as a stand-alone program, it does not require the MAIN Section, or initial entry point. Setting the Application Library option renames or removes any existing MAIN Section.


Note: Application Libraries are the appropriate spot to store a collection of shared Application Engine program Sections. It is not intended to store a specific SQL Action with in a Section. To share common SQL, use the SQL repository.
