Use the function module RS_REFRESH_FROM_SELECTOPTIONS to capture the values entered by the user in the selection screen. This FM will return the input values in the selection screen to a selection table. Selection table has the structure RSPARAMS:
SELNAME = Name of selection criterion
KIND = Type of selection (parameter or select-option)
SIGN = ‘I’ (Inclusive) or ‘E’ (Exclusive)
OPTION = e.g. ‘BT’, ‘EQ’, ‘LE’.
LOW = Lower limit
HIGH = Upper limit
