The Air Force Integrated Personnel and Pay System (AFIPPS) will seamlessly add payroll and leave management capabilities to the Military Personnel Data System, creating a single, web-based Enterprise Resource Planning software solution streamlining existing Air Force personnel and pay processes into a single self-service system for the three AF military components: Regular Air Force, AF Reserve, and Air National Guard. The system will configure the appropriate Oracle e-Business Suite Commercial-Off-The-Shelf software application modules to satisfy AF business processes and integrate the product with MilPDS, which is based on Oracle’s EBS Human Capital Management application. The delivered solution will result in table-level integration of human resource and pay data supporting a single instance of Oracle EBS, making life easier for the end user by reducing redundancy, eliminating superfluous manual process, and ensuring timely pay for all. The AFIPPS solution will subsume and supplant the existing pay and benefits computation and disbursement processes of the Defense Joint Military Pay System and the functions of LeaveWeb. It will have AF-wide applicability, encompassing military airmen in all AF components and levels of duty status exclusive of retirement pay.
