EPC diagrams illustrate business process work flows, and are an important component of the SAP R/3 modeling concepts for business engineering. EPC diagrams use graphical symbols to show the control flow structure of a business process as a chain of events and functions.

Using the EPC Diagram template in Edraw, you can quickly and easily create a high-level, visual model of your business process.

Edraw Max is a vector-based diagramming software with rich examples and templates. Easy to create flow charts, organizational charts, business process, UML diagrams, work flows, program structures, network diagrams, chart and graphics, mind map, directional maps and database diagrams. With pre-drawn libraries and more than 4600 vector symbols, drawing couldn't be easier!

The building blocks used in EPC diagrams are:

• Functions, which are the basic building blocks of the diagram. Each function corresponds to an executed activity.
• Events, which occur before and/or after a function is executed. Functions are linked by events.
• Connectors, which associate activities and events. There are three types of connectors: AND, OR, and exclusive OR (XOR).

Once completed, you can use the EPC diagram as a reference for modeling the SAP R/3 system.

3. Use the Connector tool to connect the shapes.
   1. Click the Connector tool, and then drag from a connection point on the first shape to a connection point on the second shape.
   2. When you are finished connecting shapes, click the Pointer tool.

   To reverse the direction of the arrow on a connector, on the Shape menu, point to Operations, and then click Reverse Ends.
4. To add text to a shape, select it, and then type. When you are finished typing, click outside the text block.

   Note  To edit text, double-click the shape, place the cursor where you want to change the text, and then type.
