If you want to model your own microservice, you need to create a Service in the Explorer and a BPMN model in the service panel. After creation of your service, open it to access the service panel. Each service contains already a Process folder in the service panel to which you can add BPMN models.

Adding a BPMN Model

In the Process folder you can create your BPMN models. One service can contain several BPMN models.

To create a model, hover over the Process folder to display the quick start icons and click Add Model.

Alternatively, you can open the context menu of a Process folder and select the option Add Model.

Enter a name for the BPMN model in the pop-up window Create New Model. Click Save.

Restrictions on Element Names

A BPMN model name must be unique within one service.

In addition, the following name restrictions apply to all service panel elements:

Element names...

  • ... must not be empty.
  • ... must not contain spaces.
  • ... must not start with numbers.
  • ... must not end with a period (.).
  • ... must not contain one of the following characters: <, >, :, ", /, \, |, ?, *
  • Furthermore, the following strings must not be used as element names: CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9.

When you create a new model, it opens automatically in a new tab and you can directly start modeling.

Refer to Working with the BPMN Editor for detailed information.

The new BPMN model is also displayed in the service panel and you can use option Open model to open it.

Once the model has been created, use the context menu to manage the model. Available options are:

  • Edit:
    • Instance List

  • Rename
  • Delete

Go to page BPMN Model for detailed descriptions of the context menu options.
