HIDE
The HIDE keyword is used to store data objects and their values so they can be made available when the User selects a report line. When a line is selected, the fields that were hidden are filled with the values that you hid for that line.
The user selects a line for which
data has been stored in the HIDE
area. The runtime system evaluates
field SY-LILLI to determine the
selected line.
The runtime system jumps to the
point in the HIDE area where data
for this line is stored.
The runtime system then inserts all
values stored for the selected line in
the HIDE area into their
corresponding fields.
The runtime system processes the
event AT LINE-SELECTION and
its corresponding program
processing block.
A detail list is created.
READ LINE
Use the statements READ LINE and READ CURRENT LINE to read data from the lines of existing list levels. These statements are closely connected to the HIDE technique.
Example...........
REPORT demo_list_hide NO STANDARD PAGE HEADING.
TABLES: spfli, sbook.
DATA: num TYPE i,
dat TYPE d.
START-OF-SELECTION.
num = 0.
SET PF-STATUS 'FLIGHT'.
GET spfli.
num = num + 1.
WRITE: / spfli-carrid, spfli-connid,
spfli-cityfrom, spfli-cityto.
HIDE: spfli-carrid, spfli-connid, num.
END-OF-SELECTION.
CLEAR num.
TOP-OF-PAGE.
WRITE 'List of Flights'.
ULINE.
WRITE 'CA CONN FROM TO'.
ULINE.
TOP-OF-PAGE DURING LINE-SELECTION.
CASE sy-pfkey.
WHEN 'BOOKING'.
WRITE sy-lisel.
ULINE.
WHEN 'WIND'.
WRITE: 'Booking', sbook-bookid,
/ 'Date ', sbook-fldate.
ULINE.
ENDCASE.
AT USER-COMMAND.
CASE sy-ucomm.
WHEN 'SELE'.
IF num NE 0.
SET PF-STATUS 'BOOKING'.
CLEAR dat.
SELECT * FROM sbook WHERE carrid = spfli-carrid
AND connid = spfli-connid.
IF sbook-fldate NE dat.
dat = sbook-fldate.
SKIP.
WRITE / sbook-fldate.
POSITION 16.
ELSE.
NEW-LINE.
POSITION 16.
ENDIF.
WRITE sbook-bookid.
HIDE: sbook-bookid, sbook-fldate, sbook-custtype,
sbook-smoker, sbook-luggweight, sbook-class.
ENDSELECT.
IF sy-subrc NE 0.
WRITE / 'No bookings for this flight'.
ENDIF.
num = 0.
CLEAR sbook-bookid.
ENDIF.
WHEN 'INFO'.
IF NOT sbook-bookid IS INITIAL.
SET PF-STATUS 'WIND'.
SET TITLEBAR 'BKI'.
WINDOW STARTING AT 30 5 ENDING AT 60 10.
WRITE: 'Customer type :', sbook-custtype,
/ 'Smoker :', sbook-smoker,
/ 'Luggage weight :', sbook-luggweight UNIT 'KG',
/ 'Class :', sbook-class.
ENDIF.
ENDCASE.
