• Message class: TW - R3trans - Messages

• Message number: 688

• Message text: Insert into view: Key &1 of Table &2 is not part of view &3 (&4)

What causes this issue?

An entry of the view &V3& was imported to the system. This entry did
not exist yet and was therefore inserted. All the fields in Table
&V2&, which are not contained in the view, have been set to initial
values.
The key field &V1& in Table &V2& is not included in the view either.
However, it has not been set to the initial value because duplicate
entries might result from this.
The complete value for the key field entries is &V4&.

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?

The reaction described above isusually correct. The key field &V1& in
Table &V2& was set the value that existed in the corresponding table
entry in the source system. Check the individual results of the import
if necessary.
