• This was the beginning of my career as a hands on software architect in an IC Role. Was part of the a small and focused team of architects spanning Bangalore, Germnay and Tel Aviv building the Floor Plan Manager (FPM).
• Floor Plan Manager (FPM) is a highly configurable user interface framework that extends Web Dynpro ABAP, providing a sophisticated approach to developing enterprise applications within SAP ERP systems. Introduced with SAP NetWeaver 7.0 Enhancement Package 1, FPM revolutionized how SAP applications are built by offering modification-free customization, reusable UI components, and standardized design patterns that comply with SAP UI guidelines.
• FPM is built on a three-tier architecture that separates concerns between floorplans, UI building blocks, and business logic. It had components viz. Overview Page Floorplan for multi-page applications, Guided Activity Floorplan for step-by-step workflows and Object Instance Floorplan for single-object operations. The UI building blocks were either of the one, Generic UIBBs (GUIBBs): Pre-built, configurable components provided by the framework or Freestyle UIBBs: Custom-developed components.
• The framework was built with a hierarchical configuration model with,
• Application Configuration
• Component Configuration
• UIBB Configuration
• The heart of this design was the FPM Event Phase Model
• FPM implements a sophisticated event-driven architecture with a standardized phase model that integrates seamlessly with Web Dynpro’s lifecycle. With this all major SAP applications like Human Capital Management (HCM), SAP Transportation Management (TM), SAP Supplier Relationship Management (SRM) were built on it.
• I designed and wrote the Error and Exception handling module for event loop and the UIBB full stack module for business, framework and system error and exception handling intervined with the native webdynpro system lifecycle, while also contributing to the design and architecture of the entire framework.
