Receive Activity

The receive activity defines how the business process waits for a matching message to arrive. The receive activity supports the concept of implicit assignments using the element <fromParts>.

Syntax

<receive name="ReceiveCreditInfo" partnerLink="CreditOrg" portType="cc:CheckCreditPT" operation="CheckCreditCallback"
 variable="VCreditInfo" createInstance="no">
  <correlations>
   <correlation set="AccountKey" initiate="no"/>
