Insufficients rights for operation. Data Manager

Hello all, I am working with SAP MDM Data Manager 7.1 version 7.1.06.240 and when I try to modify a registry in the SAP MDM Data Manager directly in the panel, I had this error:

Error modifying records:

The record(s) you have modified cannot be saved.

Press OK to abort the save and return to the Record Detail Pane, and then press Escape to restore the record(s).

Insufficient rights for operations. Version 7.1 (7.1.06.240)

I checked user and have all roles that she needs (Catalog Manager Content and Catalog User), and tried only with Catalog Manager Content.

What can I do?

Thanks in advance
