2493643 - Error BL201 - Log cannot be saved: Object/subobject not specified

Working over a transaction, after pressing 'Enter' or 'Saving', error is raised:
  "Log cannot be saved: Object/subobject not specified"

Or below error is raised:

 Log cannot be saved: Object/subobject not specified

     Message no. BL201

 Diagnosis

     Log save cancelled because at least one log contains no object or
     subobject.

     Object and subobject are needed to classify application logs because
     there are several log types. Only a few logs are managed in main memory
     at runtime, so this classification is not needed.

     If the logs are to be saved in the database, object/subobject must be
     specified for later retrieval.

 Procedure for System Administration

     Object/subobject can be passed when a log is created (function module
     BAL_LOG_CREATE) and changed with BAL_LOG_CHANGE.

     The possible values for object and subobject must be configured in
     transaction SLG0.
