System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Each SAP character can appear once, at maximum, in a character set but
not several times, otherwise the character set cannot be unambiguously
decoded. For example, the SAP character "space" (blank) should not be
assigned the hex codes "32" and "33". Please maintain the character set
and remove the double coding of the character.
