On activating persistent class: There is no mapping for one or more fields

256 Views

Hi all,

I'm using an ECC 6.0 system.

I've just created a persistent class and defined the persistence. When I try to activate the class activating fails and I get the message "There is no mapping for one or more fields."

I did not, in fact, use all the fields of the database table I defined the persistence on. When I do use all the fields activating the class works without a problem.

However, as far as I know it should be possible to select only some of the fields when defining the persistence (the only fields I have to select are all the key fields of the table and I've done this).

Has anybody encountered the same problem or has anybody any idea on this?

Cheers,

Kathy
