Error: TREX function is not implemented

Hi,

In our one og the SRM server trex is not working.

In TXN Trexadmin, if I select the RFC (TREX_SID) an than execute than it shows TREX function is not implemented.

I checked the trex server its up and running fine and also I checked the rfc between SRM and trex (TREX_SID) its working fine but still getting the error.

Can anybody through some light on it.

Regards,

Manish
