Table control

[Former Member]

Quick question..

While looping through the records in table control, Would the TC-Current_line be same as sy-tabix of the Internal table?

[RichHeilman]

Yes, they are.

[RichHeilman]

Why aren't they?

They are not same..

[Former Member]

yes it is same, provided there is no where condition

[Former Member]

No where conditions..

[RichHeilman]

If no where conditions, then I say that they would be the same.

Hi

Yes they are the same, if you load whole internal table in the table control.

But the sy-tabix index is active while looping internal table, the <TABLE_CONTROL>-CURRENT_LINE while looping table control.

So in the PBO and PAI you should use <TABLE_CONTROL>-CURRENT_LINE, no SY-TABIX.

Think of it this way, if you were to take current_line and read the internal table you will get the row same row that would match sy-tabix if you were LOOPing at the table.

Say, that current_line is now "4" and you do a READ, you get the 4th row of the internal table.

Read table itab index tc-current_line.

Now say, that you loop at the interal table and check when sy-tabix = 4. This is the same exact row.

Loop at itab.
if sy-tabix = 4.
* do something
Endif.
Endloop.

Using sy-tabix will have problems in comparision to current_line. If we take the case of PAI, the data flows from screen table to the internal table so the current_line points to the screen table rather than the internal table.In such a case it will be more appropriate to use current_line of table control than the sy-tabix.

hi,

<b>They are not the same</b>

Reason,

Suppose say that the table control can accomodate 5 rows on screen,and internal table containes 100 records,each time the table control scrolls down TC_current_line will reset to 1 and the sy-tabix keeps on increasing

TC_CURRENT_LINE sy-tabix

1 1

2 2

3 3

4 4

5 5

1 6

2 7

3 8

4 9

and so on

I didn't think that current_line got reset when scrolling?

I am also of the opinion that current_line does not get reset while scrolling.. I know that 'Get Cursor' resets the position while scrolling..

Hi SSG,

Both are same.

if tc-current_line = 14 and with in the loop if you

try to acceess the record sy-tabix = 14 then you both

the records are same.

If you scroll alos it can not reset.

Thanks&Regards,

Even I feel CURRENTLINE will be reset when you scroll..

Has anyone actually tested it? We need to make a final decision here so that we can close the post.

I've just tested it, in my program, current_line is following sy-tabix, it is not getting reset to 1 when scrolling, if I page down the entire table control, current_line has the same value that sy-tabix would if I loop at the interal table.

Hi

I feel While looping both works same , but if you do some change or some double click on table control

it will not refer current_line.

it will be reset to 1 after scrolling...

Hi Rich,

Just now I have checked in my table control.

If it is with in the loop current_line and sy-tabix

are same.

If it is outside the loop then current_line will

always refers the tc-top_line. so we can not read the

itab using tc-currnt_line. it doesnt pick up cursor

line.

Thnaks&Regards,

Siri.

Hi Rich

You're right, the index current_line is always link with the index (sy-tabix) of table, it won't be reset.

While looping a table control there are three index:

- SY-STEPL,

- TOP_LINE,

- CURRENT_LINE

where:

CURRENT_LINE = TOP_LINE + SY-STEPL - 1.

The values of SY-STEPL can be from 1 to N, where N is the number of rows can be displayed in TC,

TOP_LINE is the index (sy-tabix) of the record of internal table placed in the first row of tc.

So SY-STEPL'll be reset to 1 for every new scrolling, not CURRENT_LINE.

When user does a doubleclick on a record of tc, the system returns the number of record of tc, not index of internal table: i.e. the system returns SY-STEPL.

The SY-STEPL'll be reset out of LOOP/ENDLOOP of tc.

So if user does a doubleclick, the SY-TABIX has to be found out by rule above:

GET CURSOR LINE VN_LINE.

SY-TABIX = TOP_LINE + VN_LINE - 1.

READ TABLE ITAB INDEX SY-TABIX.
