We had the BW connect to R/3 which works well, but we lost the RFC connection occassionally.
When I wanna to restore or re-create the Source system in BW, I alway get error when go to "Active" step ( last step), the error message is "Error when opening an RFC connection"
I re-check all of pre-requisites:
SCC4 is open in BW and R3
SE03, system modification are open in BW and R/3
RFC user in R/3 and BW is full authorization
SM59 in both system are fine.
anyone know the reason about this problem? thanks
