These messages are displayed when you select an SFM transaction for viewing / editing / cloning, and it includes an object or field in another package for which you do not have a license. This transaction might have been designed previously by a user with license, or your license might have been revoked. This message is also displayed if the object included in the transaction has been deleted.

When this message is displayed, ensure license, profile access, and availability of the required fields and objects, and launch the SFM Designer again.
