Hi, Check for fm documentation.
Only relevant if layout parameter
LAYOUT-GET_SELINFOS of IMPORTING structure IS_LAYOUT is set.
Complex type for modifying information displayed on the selection dialog box:
mode:              'R' = Only entries passed in internal table
                          IS_SEL_HIDE-T_ENTRIES are output on
                          the dialog box. Selection information
                          obtained by the list tool by reading the
                          selection screen again (only if the report
                          is called with selection screen) are
                          replaced by the entries passed.
                   'S' = The selection information obtained by the
                          list tool by reading the selection screen
                          of the calling report again, are modified
                          by the entries of table
                          IS_SEL_HIDE-T_ENTRIES.
t_entries:         Table with selection information
t_entries-mode:   'A' = Display selection information of the current
                         table row on the information dialog box.
                  'D' = Do not display selection information of the
                         the Select option or of parameter SELNAME
                         on the dialog box.
t_entries-selname: (required only if t_entries-mode = 'D')
                   name of Select option or parameter
The following table fields are only required if t_entries-mode = 'A'. They contain the selection information to be added.
t_entries-field:  DDIC field name of the field for which selection
                   information is to be displayed
t_entries-table:  DDIC table name of t_entries-field.
t_entries-stext:  Field description on the information dialog box.
                  If t_entries-field and t_entries-table were
                  filled, this text is taken from the DDIC.
t_entries-valuf:  Selection condition from-value (external format)
t_entries-valut:  Selection condition to-value (external format)
t_entries-sign0:  (I)nclusive (E)xclusive
t_entries-optio:  All values of the option field of the Select
                  option are allowed.
The remaining fields are used internally and are irrelevant to the caller.
