Field help (AVWKEYDUP)

The default value of this field is set to Yes. It is possible to set it to No. In this case, a warning message is displayed informing that there should not be two identical keys on the index of this view. If it happened, no failure would occur but homonyms could not be detected by a simple For loop.

It is then advised to let it set to "Yes" except in specific cases where the option "No" is used to support the instructions "Read Next/Prev" on views.
