What causes this issue?

If the Logical System name needs to be changed, it should be present in
the input help(F4), i.e. it should be a valid logical system present in
the receiver.

System Response

The system checks whether it is a valid Logical System Name. If nothing
is entered, the corresponding name in the 'Logical system name in
Sender' will be copied.

How to fix this error?

The input help displays all the valid logical system names of the source
systems that are defined in the ERP receiver. Choose a logical system
name from this list. If a logical system name that does not appear in
the input help is specified, that still gets copied to the receiver
system. If you maintain same Sender and Receiver Logical system, this
might to lead to inconsistencies in Receiver.

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