SAP Message AQV121 - Name & is invalid

Diagnosis
You tried to give a query object (query, functional area or user group)a name that does not adhere to the valid conventions. This name eithercontains an invalid name prefix, is a locked name or contains invalidcharacters.
With the introduction of the namespace, the objects of the global areacan be assigned to a namespace with a name prefix having the form'/prefix/'. The prefix can be omitted and may not exceed 10 characters.The following applies to the names of query objects in the global area:

  • Names of functional areas have the form '/prefix/functarea'.

  • Names of user groups have the form '/prefix/usergroup'.

  • Names of queries have the form 'query'. Queries inherit the prefix of
  • the user group and therefore may not contain a prefix themselves.
    All names of query objects beginning with SY and having more than 4characters are reserved for future query enhancements. Objects withthese names cannot be created with maintenance transactions.
    The names of query objects may only contain letters, digits and thespecial characters - and _ (hyphen and underlining).
    The following cases result in invalid names:
    • A prefix is used for an object of the default area.

    • The prefix // or a prefix /.../ with more than 10 characters is
    • defined.
      • The name of a query is assigned a prefix.

      • A prefix that belongs to another user is used.

      • No characters follow the prefix.

      • The name begins with SY and contains more than 4 characters.

      • The name contains an invalid special character.
