How To Fix DT721 - View & kann nicht gepuffert werden

DT721 - Overview

• Message type: E = Error

• Message class: DT - Table activation (incl. indexes)

• Message number: 721

• Message text: View & kann nicht gepuffert werden

Was verursacht dieses Problem?

Selects on the checked view &V1& can return double entries because the
key is not completely defined. The buffer cannot store them because it
first sorts entries to be stored, and this is not possible in this
particular case. As a result, you cannot buffer the view in question if
you want to keep its current definition.

Systemantwort

The technical settings of &V1& are not activated.

Wie behebe ich diesen Fehler?

For an object of View type, the tecnnical settings only include
buffering attributes, but as mentioned, these are meaningless in this
particular case.
Define explicitly that buffering is not permitted for this view or
delete its techncial settings.
You can also include the key fields of the base tables in the view, that
is, you change the view definition itself first. Make sure that the key
fields are at the beginning of the View definition. Buffering is then
possible since the entries that are returned can be sorted because they
are unambiguous.
