You expand a business rule component that a colleague added to the BPEL process.

It was added automatically based on entries that your colleague made in the dialog box that appeared when the business rule component was added to the BPEL model.

Your colleague manually added this Assign element after adding the business rule component to the BPEL model.

The Assign element was automatically added when your colleague manually added the correspondingRule_Service_To_FactsAssign to the BPEL model.

You can delete this Assign because it was created for documentation purposes only.
