Process flow for the SDEP Space Utilization Utility

Module PFSD0700 is usually executed as a stand-alone process. This is because PFSD0700 executes as an exit routine in an IFP region under the IBM Fast Path SDEP Scan Utility DBF#FPUO.

Modules PFSD0800 and PFSD0900 are usually executed in the same procedure to reformat the data and update the SDEP history records using the data records that were journaled by executing module PFSD0700. This procedure can be executed as often as required to update the SDEP history file.
