i have an implementation of (java based using SAP JCO) RFC/IDOC server program which is able to connect to an external sAP system. I have recently registered on the shared test environment of SAP ES workspace system "HU2 SAP ERP 6.0 (ECC 6.00 EhP4 SP04)" . However i am not able to gain access to some of the administrative transactions (ie:-SM59,SM30,etc) from the SAP ES system ,that is required to set up my SAP program . AFAIK we do need to setup logical system/partner profiles so that SAP ES system would be able to communicate through. Is this a limitation of SAP ES system ? please let me know if there's a workaround or some way way we would be able to connect these two systems . thanks in advance ....
