ORA-26687: no instantiation SCN provided for "string"."string" in source database "string"
Cause: Object SCN was not set. If the object is a table, then both fields will be filled, for example "SCOTT"."EMP". If the object is a schema, only one field will be set, for example "SCOTT"."". And if the object is the entire database, no fields will be set, for example "".""
Action: Set the SCN by calling DBMS_APPLY_ADM.SET_%_INSTANTIATION_SCN
