Dump when fetching the Parameter.

Question

Hi Gurus,
I want to pass some parameter to when i m calling another application in the portal by calling this mehod.
CALL METHOD l_portal_manager->navigate_to_object
      EXPORTING
        system                      = 'SAP_R3'
        object_type                 = 'com.sap.obn.so'
        operation                   = 'SALESORDER'
        business_parameters         = lt_params
        USE_FORWARDPARAMETERS_OF_AL = abap_true.
In the lt_params, i ve two element  i.e. REF_DOC and FROM_DATE which contails the value also.And the value are passing successfully.
But when i m trying to fetch the data from the other component its throwing some exception "REF_DOC contain Invalid Variable". Basically what i did in the other component i have declared the REF_DOC in the inbound parameter and also in the parameter tab of the application.
Can any body tell , what exactly the problem is ?
Do i need to do some code for fetching the data .
Points'll be surely rewarded.
Thanks!

Maybe I am missing something, but you called it REF_DOC when you exported the parameter but you are trying to read SALES_ORDER_NUMBER when you import it.  Does that make sense?  Have you debugged to see what records are contained in Event->parameters?
