A lot of CALL_FUNCTION_OPEN_ERROR in production environment

[Former Member]

Hello

We have a lot of CALL_FUNCTION_OPEN_ERROR in our production environment.

An error occurred when executing a Remote Function Call.

"Protocol error when communicating with SAPGUI."

Status of connection.... "RFC DRV=GUI INPUT"

Internal error code.... "RFC_IO20"

When communicating with SAPGUI, a protocol error was detected.

The termination occurred in the ABAP program "SAPLOLEA" in

"AC_FLUSH_CALL_INTERNAL".

The main program was "RSPOLPRF ".

WE get these errors when user have 5 sessions open and then they start a printout.

Hi,

Most of the time, this error is due to users using an old SAPGUI patch level. Can you update to the latest SAPGUI patch and see if this helps?

Cheers!
