ABAP runtime error: Exception condition "FORMAT_ERROR"

The ABAP runtime error RAISE_EXCEPTION occurred with the error text "Exception Condition "FORMAT_ERROR" triggered".

Cause and Prerequisites

In the RFC destination, the character ',' or '=' was used in one of the input fields (logon data or gateway or ...). You may not use this character in this form because it is used in the kernel for separate notation and conversion routines.

Solution

In the option fields (client, language, user, password, gateway, etc.) do not use the characters ',' or '='.
