Warning

How to fix this error?

If you set up a data transfer from an SAP report, ignore the warning.
During an external data transfer from a presentation server file, the
DDIC structure must consist of purely character-like fields of the C, N
or D type. Otherwise, this leads to termination due to Unicode errors.

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