4 1 Introduction Guided Procedures (GP) provides tools and framework for modeling and executing user-centric workflows. It is aimed to support business specialists in implementing processes, and to guide casual end users through the execution of these processes, helping them to understand their work context better and to contribute more effectively. 1.1 Functions of SAP Guided Procedures Guided Procedures: Programming Model Design Time This is the environment where you model process templates and their building elements. The Web-based design time tools are accessed from the design-time work set 1. All objects that you create are available in a central repository called gallery. The object metadata is stored in the database schema of the underlying Java server. Object versioning is supported. The integration of various application types in workflows modeled with GP is enabled using callable objects 2. GP content can be exported to a deployable unit and transported across systems, either using Javaside deployment, or the transport capabilities in the ABAP stack. Runtime Once activated, process templates can be instantiated and executed in the GP runtime. The runtime user interface provides different views on the process, such as overview, detailed activities view, and so on. GP comes with an embedded implementation of the GP Workflow Engine, which enables you to execute processes without additional configuration of the processing layer. Workflow processing is executed entirely in the Java stack, and the process context information is stored in the Java server database. 1 More information: Process Modeling. 2 More information: Callable Object SAP AG Sizing SAP Guided Procedures - SAP Customers and Partners 2

5 1.2 Architecture of SAP Guided Procedures The goals of the GP framework are: to provide an environment for easier implementation of model-driven workflows to enable integration of different applications to implement transport and internationalization capabilities for GP content To meet these goals, GP provides a design time, and a runtime, as shown in the figure below 1.3 Factors that influence the performance The factors that influence the performance are given by: Complexity of the running processes. Number of process instances already existing in the database. This includes currently running processes, completed processes and terminated processes.

6 2 Sizing for Guided Procedures 2.1 Assumptions 75% of user interaction is expected in the runtime work center. 10% of user interaction is expected in viewing the task area 10% of user interaction is expected in viewing the process area 5% of user interaction is expected in the designtime work center. Up to 1000 process instances per user. 2.2 Sizing guideline For measuring the performance we have used the following hardware configuration: Intel Xeon (Hyper Threaded) CPU 3.40 GHz with 8 GB RAM which has a rating of 2070 SAPS 3 The test case for the runtime work center is a simulation of a leave request which includes 1 Sequential block and 8 actions. For the sizing guideline we have used the following formula: ((CPU/DS) * NU * SAPS of CPU )/TT*65% With: CPU/DS - CPU per Dialog step (DS), where Dialog Step is every user click which makes roundtrips to the server NU Number of Users Saps of CPU - Saps of the CPU with which we have done the measurements TT Think time of the user With our measurements the CPU/DS was for the java server and for the DB and the SAPS rating for 1 CPU is 2070/2=1035. Assumed, we have 150 users with an average think time of 60 sec, a total of 2013 SAPS are required type TT # users SAPS of CPU CPU/DS SAPS Result server db SAPS is a hardware independent unit used to describe the CPU related performance characteristics of a given hardware configuration.
