Vertical Scroll in Dynpro Table Control

[Former Member]

Hello,

I am currently having an issue with the vertical scroll control in my classic dynpro table. When I scroll down it will scroll past the first record and then freeze. I cannot scroll back up to the first record. If I try to scroll down it jumps many records and then will not let me scroll back. I have compared the coding from this screen to one that works and cannot find any differences. Is there somewhere else I should be looking? Has anyone else experienced this issue?

Thanks,

Hi Jereme Ebaugh,

Clear SY-UCOMM after it has processed.

Try this.

Check out this example program.

REPORT demo_dynpro_tabcont_loop.

CONTROLS flights TYPE TABLEVIEW USING SCREEN 100.

DATA: ok_code TYPE sy-ucomm,

save_ok TYPE sy-ucomm.

DATA: itab TYPE TABLE OF demo_conn,

fill TYPE i.

TABLES demo_conn.

DATA: lines TYPE i,

limit TYPE i.

SELECT * FROM spfli INTO CORRESPONDING FIELDS OF TABLE itab.

CALL SCREEN 100.

MODULE status_0100 OUTPUT.

SET PF-STATUS 'SCREEN_100'.

DESCRIBE TABLE itab LINES fill.

flights-lines = fill.

ENDMODULE.

MODULE fill_table_control OUTPUT.

READ TABLE itab INTO demo_conn INDEX flights-current_line.

ENDMODULE.

MODULE cancel INPUT.

LEAVE PROGRAM.

ENDMODULE.

MODULE read_table_control INPUT.

lines = sy-loopc.

MODIFY itab FROM demo_conn INDEX flights-current_line.

ENDMODULE.

MODULE user_command_0100 INPUT.

save_ok = ok_code.

CLEAR ok_code.

CASE save_ok.

WHEN 'NEXT_LINE'.

flights-top_line = flights-top_line + 1.

limit = fill - lines + 1.

IF flights-top_line > limit.

flights-top_line = limit.

ENDIF.

WHEN 'PREV_LINE'.

flights-top_line = flights-top_line - 1.

IF flights-top_line < 0.

flights-top_line = 0.

ENDIF.

WHEN 'NEXT_PAGE'.

flights-top_line = flights-top_line + lines.

limit = fill - lines + 1.

IF flights-top_line > limit.

flights-top_line = limit.

ENDIF.

WHEN 'PREV_PAGE'.

flights-top_line = flights-top_line - lines.

IF flights-top_line < 0.

flights-top_line = 0.

ENDIF.

WHEN 'LAST_PAGE'.

flights-top_line = fill - lines + 1.

WHEN 'FIRST_PAGE'.

flights-top_line = 0.

ENDCASE.

ENDMODULE.

It has the following flow logic:

PROCESS BEFORE OUTPUT.

MODULE status_0100.

LOOP WITH CONTROL flights.

MODULE fill_table_control.

ENDLOOP.

PROCESS AFTER INPUT.

MODULE cancel AT EXIT-COMMAND.

LOOP WITH CONTROL flights.

MODULE read_table_control.

ENDLOOP.

MODULE user_command_0100.

Hello Nagarajan Ramamoorthy!

I currently clear Sy-Ucomm at the end of the user command module in the PAI Section. Should I clear it somewhere else?

Thanks,

Jereme
