[Former Member]

HI,

Pressing the next button it goes to next sceen. THat screen displays fields value only its value is not initial. is there anyway ,instead of checking fields one by one..

i tried to do like this

field-symbols: <l_FIELDNAME> type any.

loop at screen.

ASSIGN TABLE FIELD (SCREEN-NAME) TO <l_fieldname>.

IF <l_FIELDNAME> IS INITIAL.

SCREEN-INVISIBLE = 1.

SCREEN-INPUT = 0.

ELSE.

SCREEN-INVISIBLE = 1.

ENDIF.

MODIFY SCREEN.

endloop.

The Dynamic Internal Table SCREEN is created for each field in the selection screen. i.e. every field in the selection screen with have a inter SCREEN table with all the 14 fields. To hide the fields in the Selection Screen you have to pass the SCREEN-INVISIBLE parameter for each of the field.

Rewards if useful.

SCREEN-ACTIVE = 0.

ELSE.

SCREEN-ACTIVE = 1.
