Entry already exists for this selection

What causes this issue?

A competing entry already exists in the table ICFATTRIB.
This could be because, for example, a
non-client-specific or non-user-specific
data record already exists, and you are attempting to create a
client-specific or user-specific data record. This could cause the
follow-on applications, such as debugging, traces, recording, or
ATRA, to be called with incorrect parameters.

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 your entry to overwrite the existing data record, then
deactivate the existing record. To do this, choose
<ZK>Deactivate</> in the menu in the relevant function (debugging,
trace, recording, or ATRA), and deactivate the record.
You can then activate your selection.
If you do not want your entry to overwrite the existing entry, then
no further action is required.
