table cntl--scrolling

Former Member — Fri, 17 Nov 2006 07:36:58 GMT

hello all,

i am using table cntl. i am selcting records in table cntl (lt_final) and putting those selcted records in another tablegt-final). the problem is when ever i scroll down to selct another record, already selected record is getting duplicated in gt_final which is un wanted. How can correct that. The logic i am using is.

<u>flow logic.</u>

LOOP AT lt_final.

FIELD lt_final-sel MODULE check_sel.

ENDLOOP.

MODULE user_command_2000.

<u>in main program</u>

MODULE check_sel INPUT.

IF lt_final-sel = 'X'.

MODIFY lt_final INDEX tab_cntl-current_line.

APPEND lt_final TO gt_final.

ENDIF.

ENDMODULE. " check_sel INPUT

Can any one help me to avoid duplicate record getting into gt-final.

regards

rahul

1st you need to understand how the table control works...

Say in a table control there are 5 rows... with data as a,b,c,d,e in rows 1,2,3,4,5 respectively.

i.e . field(1) = a , field(2) = b .... field(5) = e ...like that...

Now if you scroll down to see the values after e i.e. f,g,h..... the row no does not change...

If u press the scroll down button once.. this is how the situation looks like..

field(1) = b , field (2) = c ..... field(5) = f

I hope this is clear...

I am not sure how ur code looks like... but the point is that if you scroll the button once..

then u need to reduce the index counter once...

I hope this is not confusing you... So check ur code... see the values in debugging mode and you will find the answer your self...

Plz .. tell if it was helpful and reward points...

helo kesi,

if you won't have consideration about sorting for your gt_final then you can user combination sort and delete adjacent duplicates. for example :

sort gt_final.

delete adjacent duplicates from gt_final.

there are some others tricks if you won't change the itab content sequece.

Hi kesi,

See when you select records and scroll down the PAI will get executed and selected records will appended into your internal table.And you have written that selected records your are putting into internal table .That means to put the data into internal table you are triggering some event(Save button or some other).That time also the selected data will go and appepending the same data.So to test this select the records in table control and enter the "/H"(Debugging) on command field press enter and now Scroll down .You can see what is happing there .

See the below code .

If sy-ucomm eq 'Save' (Say here save is your button)

IF lt_final-sel = 'X'.

MODIFY lt_final INDEX tab_cntl-current_line.

APPEND lt_final TO gt_final.

ENDIF.

endif.

Hope this will solve your problem.

Don't forget to reward points if it helps you.

hi,

To handle Scrolling you need to add the following.

U just got to do this thing in ur logic of PBO

describe table it_final lines N.

tab_cntl-lines = N.

This will solve ur scrolling issue of table control
