All settings that you make in this row refer to the corresponding column of the output table. REF_FIELD: You must fill this field if: • the output table field described by the current entry in the field catalog has a corresponding field in the Data Dictionary and • the field name in the output table is not identical to the field name of the field in the Data Dictionary. If the field names are identical, it is sufficient to specify the DDIC structure or table in field REF_TABLE of the field catalog. REF_TABLE: You must fill this field only if the output table field described by the current entry in the field catalog has a corresponding entry in the Data Dictionary. Using this assignment, the ALV Grid Control can copy the text for the column header from the Dictionary.
