RFC Connection Error

BW Experts:

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

Hi jie,

RFC connection is manly defined by three parameters: Target host, Sys ID, Sys No. try to check again or ask your basis about any change on these 3 parameters in R/3 System.
