Answer Posted / teknath bera
Field catalog containing descriptions of the list output
fields. You can use fields of the catalog to determine the
number format and column properties of the list to be
displayed.
The field catalog contains more than 60 fields, some of
which are only used internally. The field catalog is
defined in the Data Dictionary through table type
LVC_T_FCAT.
We can get field description by calling function module
REUSE_ALV_FIELDCATALOG_MERGE
