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 conditions
In the RFC destination, the character ',' or '=' was used in one of the input fields (logon data or gateway or ...). This character cannot be used in this form because it is used in the ABAP kernel for separate notation and conversion routines.
Solution
Do not use the characters ',' or '=' in the option fields (client, language, user, password, gateway, and so on)
