Diagram Elements

The ODFS provides diagram elements for configuring a flow. You can drag a diagram element to the canvas on the right or click a diagram element to use it on the canvas.

Some operations under the current menu are controlled by separate permissions. If related operation permissions are not configured, the corresponding operations are not supported. For details about the operation permissions that can be configured separately, see Table 1.

What are the tips for drawing a flowchart?

• When dragging a diagram element, observe the line between the new diagram element and the existing one on the canvas, and align the diagram elements based on the tips.
• Drag a diagram element to the canvas, and then click to drag it.
• In a diagram element, a cache object cannot be duplicate. The cache variable name must be unique. Otherwise, the latest cache variable name is used.

• SMS Sending (Expired and Not Recommended)
  This diagram element is used to invoke an interface for sending SMS messages to send an SMS message based on a template.
• JSON Data Invoking (Expired and Not Recommended)
  This diagram element is used to parse and assign values to call-associated data in JSON format.
• Composite
  A composite diagram element is a combination of multiple diagram elements that an operator customizes for simplified operations.
