RFC destination BW could not be created in the source system

Hi,

Recently I installed BI 7.0 on Win 2003 and try to create a SAP system in RSA1.

I try to connect R/3 system (on UNIX) and getting RFC connection error u201CRFC user logon failed. Check the connection.u201D & u201CRFC destination BW could not be created in the source systemu201D. However, I test the connection and it is working fine.

Please suggest the solution.

Regards,

Rajesh
