Diagnosis
In the view, not all of the mandatory fields were included as key fields. The key of the view therefore is not unique.
System Response
All the fields are regarded as key fields in order to guarantee that the key lengths are unique.
Procedure
For views with a large number of fields, this could have a negative effect on the performance for the language construction described below. In this case, all the mandatory key fields should be included in the view.
Notes
The key information is relevant for the ABAP/4 language constructs SELECT SINGLE, SELECT ... ORDER BY PRIMARY KEY and SELECT ... FOR ALL ENTRIES.
In these cases, SELECT SINGLE is handled like a simple SELECT ... ENDSELECT, where the first (random) record found is returned.
ORDER BY PRIMARY KEY and (indirect) SELECT FOR ALL ENTRIES sort according to all fields in these cases.
