Diagnosis
The creation of names for generated objects failed.
The conditions technique generates different DDIC and repositoryobjects adjusted to user settings to ensure good performance.Particular naming conventions suffice for these objects. Object namesare made using the corresponding meta object available in Customizing.Presumably, the Customizing of this Meta-object is inconsistent.
Example: for the Meta-object "condition table", two DB tables, a DBView, three table types and different structures are generated. If thename creation for a DB table fails, Customizing of the correspondingtable is presumably inconsistent.

Procedure
You will find further error messages in the log regarding the currentobject. Make sure the object concerned is consistent in itself andrepeat the transaction.
