Why COBOL and SQR processes are made API aware ?

An API aware process is able to update its process status.

COBOL and SQR processes API aware, use the standard API code provided by PeopleSoft.
Crystal processes have API built into PSCRRUN.EXE.

The API code updates the Process Scheduler the process’ runstatus, completion code, message set, and message number.

The API call is given just before it COMMITs processing.

If an error is encountered in the process, the code performs the rollback and updates the runstatus to “unsuccessful,” COMMITs this update and then terminates.
