Once you export your process to an XML file, you need to copy that XML file to the MDM defined location for workflow files.
Workflows in MDM are saved in either of the following locations:
A common workflow location ($MQ_COMMOM_DIR/standard/workflow) or
An enterprise specific workflow location ($MQ_COMMOM_DIR/<enterprise internal name>/workflow)
Note: The Enterprise specific workflow location takes precedence over the common workflow location. If the required workflow is not found in the enterprise specific workflow location, the application will look in the common workflow location.
