Integration between PeopleSoft Environments using PeopleSoft Services Listening Connector

We have implemented a synchronous integration point btwn our PS HCM (V9.2, PT 8.54.05) and FSCM (v9.2, PT 8.54.12)  to bring in a necessary account related data from FSCM into HCM. However rather than using the traditional PeopleSoft Target Connector, our integration point uses PeopleSoft Services Listening Connector. The HCM system calls a FSCM service operation using the said connector and the FSCM system processes and sends back the response message. The code looks something like this:

From the HCM System:

/*Request Info*/

SQLExec("select URI_TEXT from PSNODEURITEXT WHERE MSGNODENAME = 'PSFT_EP' and URI_TYPE = 'PL'", &URL);

   &posnum = Find("psp", &URL);
