The purpose of the message transfer is to send data between Requests running from the same Process model since each Pool object represents its own Request with its own distinct Request data. A Message Flow object can connect from the Message End Event object to the object listening for its message. A Message End Event object functions as follows during a Request: - The Message End Event object triggers when the Request using it completes. - The Message End Event object sends its message. The message has a name which is a placeholder for the Request data it sends to the catching object. - If the message name matches that for which the catching object is listening, then that object triggers. Otherwise, the message is ignored. --- ## Add a Message End Event to a Process **Permissions** - Processes: Edit Processes - Processes: View Processes See the [Process](/v1/docs/permission-descriptions-for-users-and-groups#processes) permissions or ask your Administrator for assistance. Your user account or group membership must have the following permissions to configure a Message End Event object in the Process model unless your user account has the **Make this user a Super Admin** setting selected: Processes: Edit Processes Processes: View Processes See the [Process](/v1/docs/permission-descriptions-for-users-and-groups#processes) permissions or ask your Administrator for assistance. Add a Message End Event object from one of the following locations in Process Modeler: - **Object Panel:** Located to the left of the Process Modeler, the Object Panel contains various process modeling objects. - **Object Bar:** Located at the bottom of the Process Modeler, the Object Bar contains [pinned](/v1/docs/process-modeler#pin-and-unpin-objects) Process modeling objects for quick access. Add from the Object panelAdd from the Object bar Follow these steps to add a Message End Event from the Object panel to the Process model: 1. Ensure that the Object panel is visible. If not, click the **Add** icon ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/7c9eb065-4888-4ad5-b471-5be8a64fde54.png) from the Object bar at the bottom. 2.

Click **Confirm**. The new object replaces the Message End Event object with its default settings and color. --- ## Settings The Message End Event object has the following panels that contain settings: - [**Configuration**](/v1/docs/message-end-event#configuration-panel-settings) panel - [**Data Inputs & Assignments**](/v1/docs/message-end-event#data-inputs-assignments-panel-settings) panel - [**Advanced**](/v1/docs/message-end-event#advanced-panel-settings) panel --- ### Configuration Panel Settings The Message End Event object has the following settings in the **Properties** panel: #### Edit the Object Name An object name is a human-readable reference for a Process object. Process Modeler automatically assigns the name of a Process object with its object type. However, an object's name can be changed. Follow these steps to edit the name for a Message End Event object: 1. Select the Message End Event object from the Process model in which to edit its name. 2. Ensure that the **Configuration** panel displays. If not, [show it](/v1/docs/show-configuration-settings-for-a-process-model-object). The **Name** setting displays. This is a required setting. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/bf8003de-5105-424e-a331-ce13ae8078e6.png) 3. In the **Name** setting, edit the selected object's name and then press **Enter**. #### Edit the Message Name The Message End Event object uses a message name as a placeholder for the Request data that this object sends to a catching object. When a Message Start Event object or an Intermediate Message Catch Event object listens for a message, it references the Message End Event object's message name. Follow these steps to configure how to trigger a Message End Event object: 1. Select the Message End Event object from the Process model in which to configure its message name. 2. Ensure that the **Configuration** panel displays. If not, [show it](/v1/docs/show-configuration-settings-for-a-process-model-object). Panels to configure this object display. 3. Expand the **Configuration** panel if it is not presently expanded, and then locate the **Message Name** setting. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/5c83ad8c-235c-47f4-927c-a48380b1888e.png) 4. In the **Message Name** setting, edit the message name that a catching object references to listen for the Message End Event's message. --- ### Data Inputs & Assignments Panel Settings The **Data Inputs & Assignments** panel allows designers to define and map fields that make up the message payload. Each payload field can be built using [FEEL Expression Syntax](/v1/docs/feel-expression-syntax) to generate dynamic content. #### Add Data Inputs & Assignments Follow these steps to configure **Data Inputs & Assignments** for an Intermediate Message Throw Event: 1. Select the Intermediate Message Throw Event in the Process model. 2. Ensure the **Configuration** panel is visible. If it is hidden, [show it](/v1/docs/show-configuration-settings-for-a-process-model-object). Panels to configure this object display. 3. Expand the **Data Inputs & Assignments** panel if it is not already expanded. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/Data Input & Assignment Empty.png) 4. Click **+Add Data Input**. A new Data Input Name entry displays. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/Data Input Name.png) 5. In **Data Input Name**, enter the name of the data input. 6. Click **+Add Assignment** to define the payload fields. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/Assignment Expressions with FEEL.png) 7. In the **From**, enter the data to map. Use FEEL expressions to construct dynamic values, for example, concatenate the variables `firstname` and `lastname` using `firstname + " " + lastname` . 8. In the **To**, enter the target payload field name. For example, enter `completeName` . 9. Add additional assignments as needed, then click **Save**. The assignment expressions displays in the list. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/Assignment Expression Added.png) --- ### Advanced Panel Settings #### Edit the Node's Identifier Value Process Modeler automatically assigns a unique value to each Process node added to a Process model. However, a node's identifier value can be changed if it is unique to all other nodes in the Process model, including the Process model's identifier value. > [!WARNING] > All identifier values for all nodes in the Process model must be unique. Follow these steps to edit the identifier value for a Message End Event object: 1. Select the Message End Event object from the Process model in which to edit its identifier value. 2. Ensure that the **Configuration** panel displays. If not, [show it](/v1/docs/show-configuration-settings-for-a-process-model-object). Panels to configure this object display. 3. Expand the **Advanced** panel if it is not presently expanded. The **Node Identifier** setting displays. This is a required setting. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/12f56dcc-62b5-4148-84ac-26378f2d1dba.png) 4. In the **Node Identifier** setting, edit the Message End Event object's identifier to a unique value from all nodes in the Process model and then press **Enter**.
