loop with table control

[Former Member]

Hi All,

I have a querry regarding table control. In standard sap screen's flow logic there is 'LOOP WITH CONTROL D0127' statement. This statement will loop at that table control only for 8 Records in that table control, for the remaining records this statement will not get executed.

since sy-loopc will be 8(open lines of table control).

If i scroll down that table control that problem is getting solved, but i want it without scrolling down table control.

Help or suggestion regarding this will be greatly appreciated.

Thanks and regards,

Hi Srinivas,

Befor writing 'LOOP WITH CONTROL D0127', you have to find the number of rows in the itab using describe statement. Try do like this in flow logic.

process before output.
  module status_0100.
  loop with control D0127.
    module fill_table_control.
  endloop.
--
se38
module status_0100 output.
  describe table itab lines fill.
  D0127-lines = fill.
endmodule.

For more information please check standard program <b>DEMO_DYNPRO_TABCONT_LOOP</b> and <b>DEMO_DYNPRO_TABCONT_LOOP_AT</b>.

Hi Raghav,

Thanks for your sugestion.

That screen is sap Standard screen i am not authorized to change the flow logic of that screen.

Is there any other method to view last record without scroling table control, that is when i fill that table control the last record should be visible to me.

Thanks and regards,

Hi,

Hope it is not possible. Suppose if you have data for some 10K records , it would not possible to display all the records in the screenn with table contol , at the max we can drag the table control for the whole screen and we can display that many number only , for the other records <u>we have to scroll down</u> .

Hi

You can't do it, because the table control is like an internal table with only N rows where N is number of displayed rows.

So if you have designed only 8 rows in a table control by screen painter, the system variable SY-LOOPC'll be 8 and SY-STEPL'll be able to tha value from 1 to 8.

In this situation the LOOP WITH CONTROL statament can loop only 8 records of the internal table and the field CURRENT_LINE of table control is the number of the record of internal table is beeing read.

The rule to calculate CURRENT_LINE is:

<TC>-CURRENT_LINE = <TC>-TOP_LINE + SY-STEPL - 1.

If you want to read the remaining records you should do a reading out of LOOP of table control.

PROCESS PAI.

LOOP AT

MODULE READ_DISPLAYED_RECORDS.

ENDLOOP.

MODULE READ_OTHER_RECORDS.

MODULE READ_OTHER_RECORDS.

• Reading records form 1 to TOP_LINE

DO.

IF SY-INDEX = <TC>-TOP_LINE. EXIT. ENDIF.

READ TABLE ITAB INDEX SY-INDEX.

ENDDO.

• The first records not displayed:

REC = <TC>-TOP_LINE + SY-LOOPC.

DO.

READ TABLE ITAB INDEX REC.

IF SY-SUBRC <> 0. EXIT. ENDIF.

REC = REC + 1.

ENDDO.

ENDMODULE.
