| 3 | The Loop BPMN Connector is designed to facilitate looping behavior within scenario diagrams. It enables processes to iterate over a set of files multiple times based on specified conditions. | ||

| 8 | |||
| 9 | |||
| 10 | To use the Loop BPMN Connector effectively, follow these steps: | ||
| 11 | |||
| 12 | 1. **Place Connector:** Drag and drop the Loop BPMN Connector onto your scenario at the appropriate location where looping behavior is required. | ||
| 13 | 1. **Connect Inputs and Outputs:** Connect the input and output connectors of the Loop BPMN Connector to the relevant elements in your BPMN diagram (the connector must have exactly 2 inputs and 2 outputs). | ||
| 14 | 1. **manage deploiment error** : when missing or adding a required output or input, it could forbid the sceanrio deploiment. | ||
| 15 | [[image:1714408723108-457.png||height="301" width="639"]] | ||
| 16 | 1. **Handle Loop Exit:** Ensure that the exit output is connected to the appropriate elements in your scenario diagram to handle the termination of the loop. | ||
| 17 | |||
| 18 | = Example = | ||
| 19 | |||
| 20 | in the following example, we created scenario where multiple files are loaded by LoadFile connector (//LoadFile2//), and proceeded by Loop1. | ||
| 21 | |||
| 22 | the Loop1 has 2 inputs ( 1 to ensure triggering the connector, and other to ensure the loop over) and 2 outputs (1 for the loop, and other for the exit) | ||
