How can I change the cardinality of Model Node?

Hi everybody

How can I change the cardinality of Model Node?

Previous:

I import a Model RFC, and some nodes has the cardinality 0..1, but with this configuration, when I bind to the text fields of my webdynpro and deploy, all my fields text are unables when I shows the webdynpro.

I check RFC and all the fields and estructures are obligatories.
