The purpose of this wiki is to explain why in some cases the "Unicode" option in SM59 is not editable/greyed out.
In some cases the Unicode option is not available, this wiki will explain why.
On a Non-Unicode system it is not possible to change the Unicode settings in SM59, even though you are in edit mode.
You will see something like the following:
If you create an RFC connection in a UNICODE system you must specify Unicode settings; but in an NON-UNICODE system this is automatic. So, setting the value on a Non Unicode system is not possible and is also not required because the Tab for setting MDMP & UNICODE in SM59 is only valid (activated) on the UNICODE system. This setting on the Non-Unicode
system is irrelavent.
