Did you find any solution for this Map inbound data?. We are also facing similar issue after migrating from Pega6.1 SP2 to Pea 7.2.2 and in our case. New Pega 7.2.2 Rule-Connect-SOAP calls InvokeAxis2 activity in Pega-IntegrationEngine:07-10-27 OOTB ruleset and the step numbers are different but operations are similar.

1. Step – 14 Rule-Connect-SOAP InvokeAxis2 Pega-IntegrationEngine:07-10-27 Soap Service Call to load 1.5 MB PDF - 500 - 700 msec.

   pxConnectClientResponseElapsed=604 msec;

2. Step -17 Rule-Connect-SOAP InvokeAxis2Pega-IntegrationEngine:07-10-27 Map inbound data to clipboard takes more time as the PDF size increases. 1 MB takes 25 – 30 seconds, for 1.5 MB takes 50 – 80 seconds

   pxConnectInMapReqElapsed=50274 msec;

PEGA0020*50890*500* - has exceeded the threshold of 500 ms: 50,890 ms;pxConnectOutMapReqElapsed=0;pxConnectClientResponseElapsed=604;pxConnectInMapReqElapsed=50274;*
