Cause
There is a model in the database that is based on a user-defined model type that no longer exists in the ARIS method configuration. In this case, the user-defined model type can no longer be used to find the model. There are two possible reasons why the model type is no longer available:
The method filter used does not contain the user-defined model type.
The model type has been intentionally deleted from the ARIS method configuration.
Solutions
If a method filter exists on the server or tenant that contains the user-defined model type, the user can log in to the database again with this method filter. The model is based on the user-defined model type again.
If there is no method filter on the server or tenant that contains the user-defined model type, the system administrator can use ARIS Architect to import the method filter into the server/tenant and the user can log in to the database again with this method filter. The model is based on the user-defined model type again.
If the user-defined method filter has been intentionally deleted, the system administrator can reorganize the database on the Administration tab of ARIS Architect with the Automatically replace missing item types option. This resets the model type to the standard ARIS model type. After logging into the database again, the search can find the model again if it is performed using the standard ARIS model type.
