View validation error after view copy from TEST to PRODUCTION, on ADX file ...

SOLVED

Hi.

I updated the order header view, adding a new field: allthing works correctly in Test environment!

For publish this upgrade into PRODUCTION evnvironment, I used "copy" operation, from TEST to PROD: it was successful.

When I tried to activate the view upgrade, with VALIDATION operation, SageX3 return this error:

What's mean?

What can I do for resolve this issue, and activate the view upgrade?

Thanks for your support.
