In Talend Studio,
deploy the updated workflow process Product_Product to the Talend MDM Server.
Log into Talend MDM Web UI,
and launch the process Request Price Change for the
product data record whose price you want to change.
Log into the Bonita BPM web portal, and assign the price request task to the
appropriate user, for example, a commercial user who is responsible for product
pricing in a real-life project.
Take the task as the assigned user, and check that the customized form works
well as expected.
