The GETPROCESSDATA workflow application lets you retrieve process data values of a specified request. This application is useful for inter-process communications.

When used as a first sub-process action, GETPROCESSDATA provides a flexible alternative to sub-process parameters, since there are no versioning management constraints with the parent process.

#### Required parameter

| Parameter | Type | Direction | Description |
| --- | --- | --- | --- |
| `REQUEST_ID` | Numeric | IN | The ID of the request that contains the process data to retrieve |

#### Activity parameters

The other parameters are defined in the workflow action according to your needs.

**Parameter name:** The name of the remote process data to retrieve.  
**Receive the value into:** The process data to update.

#### Example

To retrieve the value of the `COMPANY` process data into the `CUSTOMER_COMPANY` process data:

**Parameter name:** `COMPANY`  
**Receive the value into:** `CUSTOMER_COMPANY`

Process data datatypes must be same.

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