Transport method CTS is not available when trying to do an export in Portal

Hi,

I have configued CTS+ for Portal using PI as our communication system.I have checke RFC destination sap.com/com.sap.tc.di.CTSserver in NWA of Portal and it is working fine.

Please find my observation below:-

I changed WBO_GET_REQ_STRATEGY = TAGGED instead of SMART. After that I am getting CTS option and if I create the transport request manually

then I am able to export it.

However if I set WBO_GET_REQ_STRATEGY = SMART it does not create the transport request automatically which is happening in our sandbox

system. Also during this step we are getting an ABAP dump each time we are getting "Transport method CTS not available" error in Portal.

Runtime Errors         DYNPRO_SEND_IN_BACKGROUND

Error analysis
    During background processing, the system attempted to send a screen to a
     user.

    Current screen: "/RSC/SAPLDEV_RM_UTILITIES " 9050.

    Additional system information:
    "currently running as cpic server"

Thanks,
