Settings for Code Pages 
Tab page Unicode in transaction SM59 contains various code page handling settings.
You can make the following settings for code pages:
Communication type with target system
Here, you specify whether the RFC Destination is a Unicode system or a non-Unicode. Using the pushbutton Unicode Test you can call this information from the target system.
You can select various options for non-Unicode destinations:
Use default codepage 1110.
The specified default codepage is used when you choose this option.
Explicit Code Page
With this option you can define a fixed code page for this destination.
Character Conversion
Here, you define how conversion errors are handled:
RFC continues despite conversion errors, with non-convertible characters being replaced by replacement character '#' (default).
RFC terminates for conversion errors (short dump).
RFC ignores conversion errors where non-convertible characters are replaced by a freely-selected replacement character.
