We have upgraded a BW 3.5 System to BI 7.0. After the upgrade, the RFC connections are giving problems. When I click test connection, it works. But remote login is not working.
The RFC trace file gives the error "
*CLIENT > SREAD [EndWrite...StartRead] Time 0.000000
======> You are not authorized to logon to the target system.
ABAP Programm: RSRFCPIN (Transaction: SM59)
Called function module: RFCPING
User: xxxx (Client: xxx)
The destination BI is upgraded to 7.0. But the source R3 system is 4.0B. The hostname, instance number are correct. The source and destination users are dialog users and the RFC Connection is 3. Please help me in finding the problem. Points will be awarded for any kind of help.
