The UPDATEPROCESSDATA application allows you to update process data associated to a request. It provides a simple solution for inter-process communications.

### Required parameter

| Parameter&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; | Type&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; | Direction | Description |
| --- | --- | --- | --- |
| `REQUEST_ID` | Numeric | IN | This parameter must contain a valid request ID |

The optional parameters are the process data to update (the parameter name is the process data name). You must define those parameters in the corresponding action parameters.

### Example

You want to update the `AMOUNT` data with the value of the `AMOUNT_UPDATE` process data. The request ID to update is stored in a `REQUEST_ID_UPDATE` process data.

Create a workflow action using UPDATEPROCESSDATA with the following parameters:

- `REQUEST_ID` send the value of: Data: `REQUEST_ID_UPDATE`

- `AMOUNT` send the value of: Data: `AMOUNT_UPDATE`

You may have to add an exception management to handle possible errors (e.g. invalid request ID).
