Hi All

I am trying dynmically connect to sap r/3 backend through JCO.

i have created a WD Model at design time giveing the detail of r/3 system and the JCOs.during run time i am changing the connection parameters to connect to adifferent r/3 which has the same BAPI as in the previous r/3 and trying to retrieve data from the second.

While connecting i am getting the following error
