How To Fix EDCMP427 - Error during remote access: & &, display of source without enhancements

EDCMP427 - Overview

• Message type: E = Error

• Message class: EDCMP - ABAP Workbench: Splitscreen editor

• Message number: 427

• Message text: Error during remote access: & &, display of source without enhancements

What causes this issue?

The function module call by RFC failed. Therefore, the source could not
be read in the remote system using the special function for importing
enhancement implementations and will be shown without any existing
enhancements.

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?

If you want to show the enhancements in the remote system, you must use
an RFC destination with a user with the relevant authorizations.
If you generally do not want enhancements to be displayed for the
comparison, the option "Do Not Display Any" must be set in the editor
setting for enhancement implementations.
