Error code - SOLAR_0073

The error is reported during the recovery of a project configuration.

Error message

The configuration of project <Name> contains unknown user-defined model or symbol types in the method configuration.

Cause

You are trying to restore a project configuration in whose method configuration user-defined symbol or model types are defined. However, these types are not available to the current tenant.

This can happen if you import databases for whose SAPĀ® projects the project configuration described was created, but these types were not used. If symbols were defined for special documents, for example, but these documents do not occur in the project, these symbols are not created during the import.

Solution

If these user-defined model or symbol types are available on another tenant, create a database there and use the missing types. After you have saved the database and restored it on the tenant, the missing model or symbol types are now also available there.

Otherwise, the method configuration for these model or symbol types is lost.
