This error indicates that the system cannot find any field catalogs defined for the report or transaction you are trying to execute.
  Causes:
  
  Missing Field Catalog Definition: The most common cause is that the field catalog has not been defined for the report or ALV grid you are trying to use.
  Incorrect Program Logic: The program may not be correctly set up to generate or reference the field catalog.

  DATA: lt_fieldcat TYPE lvc_t_fcat,
        ls_fieldcat TYPE lvc_s_fcat.
  
  CLEAR ls_fieldcat.
  ls_fieldcat-fieldname = 'FIELD1'.
  ls_fieldcat-seltext_m = 'Field 1'.
  APPEND ls_fieldcat TO lt_fieldcat.
  
  " Repeat for other fields as necessary
