Creating Property Aliases for IDCorr

You create the following two property aliases for the IDCorr correlation set:

Map IDCorr to the LoanAppResponse message type part of the receiveSecond receive activity. This receive activity is associated with the SecondReceive partner link (defined by the SecondFileRead.wsdl file).
Map IDCorr to the CustResponse message type part of the receiveThird receive activity. This receive activity is associated with the ThirdReceive partner link (defined by the ThirdFileRead.wsdl file).

To create property aliases for IDCorr:

In the Structure window, right-click Property Aliases.
Select Create Property Alias.
In the Property list, select IDCorr.
Expand and select Message Types > Project WSDL Files > SecondFileRead.wsdl > Message Types > LoanAppResponse_msg > Part - LoanAppResponse.
In the Query field, press Ctrl+Space to define the following XPath expression:
```
/ns4:LoanAppResponse/ns4:APR
```
Click OK.
Repeat Step 1 through Step 3 to create a second property alias for IDCorr.
Expand and select Message Types > Project WSDL Files > ThirdFileRead.wsdl > Message Types > CustResponse_msg > Part - CustResponse.
In the Query field, press Ctrl+Space to define the following XPath expression:
```
/ns6:CustResponse/ns6:APR
```
Design is now complete.
Click OK.
