Dynamically inserting new line in Internal table

Hi,
Can anyone help me how to insert a new line dynamically to the internal table.
Assume there are 5 records that has been added to ITAB.
In that if a particular field in that ITAB crosses the limit 10 then i have to split that line into two lines with the same data except that Par.field as 5 and the other record has 5.
In the third record that particular field has value 10.
Loop at ITAB.
 Once i found that field has 10 then how to insert a new line dynamically over here to add another record.
endloop.

Hi..
Hi..
try this..
loop at itab.
if ( i found that field <f1> has 10 ).

@Inserting Records in an Internal Table

Hi,
How can I Insert records in an internal table..such that i can insert the records somewhere in the middle based on the entry in a field?

INSERT wa INTO TABLE itab INDEX idx .
Effect
This variant can only be used for standard tables and sorted tables. Each line line_spec to be inserted into the line before the table index idx and the table index of the following lines is increased by one. A data object of the type i is expected for idx.
If idx contains a value equal to the number of the existing table lines plus one, the new line is appended as the last line in the internal table. If idx contains a greater value, no line is inserted and sy-subrc is set to 4.
An exception that cannot be handled is raised when:
idx contains a value less than or equal to 0
A line to be inserted would cause a duplicate entry in tables with a unique table key
A line to be inserted would disrupt the sort order of sorted tables
Within a LOOP loop, you can omit the addition INDEX. Each line to be inserted is inserted before the current table line of the LOOP loop. However, if the current line is deleted in the same loop pass, the response is undefined.

New Line after every 900 lines in internal table

HI,
I have an internal table and that is sorted by company code. i.e it is grouped according to company code.
Now i want to check in particular groups of company code if the lines of internal table is > 900 or not.
And if it > 900 i have to insert new line.
How to do that?

Hi
Please check the code..I think it will solve ur problem
TYPES : BEGIN OF x_data,
         name TYPE char10,
        END OF x_data.
data: i_data TYPE STANDARD TABLE OF x_data INITIAL SIZE 0,
      wa_data TYPE x_data,
      counter TYPE n LENGTH 2 .
DO 5 TIMES.
CLEAR : wa_data.
counter = counter + 1.
CONCATENATE 'subha' counter INTO wa_data-name.
APPEND wa_data to i_data.
ENDDO.
CLEAR : counter,
        wa_data .
DESCRIBE TABLE i_data LINES counter.
IF counter > 4.
counter = 5.
wa_data-name = 'TEST'.
INSERT wa_data INTO i_data INDEX counter.

Report Painter insert blank line after report header

Hi Expert,
I have a problem to insert a blank line (a spacing) after the report header of my customized report painter.
For example, in standard cost center report, S_ALR_87013611, there is a small box listed information like cost center/group ... and reporting period.
Right after reporting period, the report header box ends, and there is a space line between it and the cost element data ...
For my customized report painter, I cannot make this space line.
I tried edit > row > insert blank line ... but not successful ... kindly advise.
Thanks and regards,
-CK

Hi
In KKO2 go to output tab, here under layout, tick header and then press pencil symbol and in the editor you write your header. I think this will give you desired result.

How to insert record inside the internal table in below code

Hi all,
My requirement is to find the sub-total and need to insert in between the internal table.
You can see the output ....where I want the sub-total F2 when 1 & 2 combindely , 3 , 4& 5 combindely .Please check it and let me know is it possible
when i am using modification it is not creating extra row inside the table instead it is modifying one row and putting the total there.
For ex: the origianl output is
F1   F2       F3
A      1          1
B      1          1
F      2          1
D      3          1
E      4          1
C      5          1
We want to display all the total of f2 of 1-2 , 3 , 4-5
so expcected output is
F1   F2       F3
A      1          1
B      1          1
F      2          1
     *              3 ->This is the sub-total of 1& 2 of f2
D      3          1
        *           1 ->this is the sub-total of 3
E      4          1
C      5          1
      *             2 -> this is the sub-total of 4 & 5
= space
But coming output is
A 1          1
B 1          1
*             3 -> it is modifying the F row and inserting the total .Total is comong correct but is shoule insert instead of modifying the record!!
*           1
E 4          1
*             2
Please help how to insert the row total at the end of the chage of field
Please find the below code ..Due to space problem i am attaching below

I am trying to upload the large file of tab delimited data into a SAP internal table. I am basically stuck with the fact that there are multiple lines and multiple columns in tab delimited file. There are around 300 columns which are tab delimited and separated
For e.g (* indicates tab)

Hi Amolsonaikar,
you may try like this:
TYPES:
begin of line,
t_field type table of string,
end of line,
t_line type table of line.
DATA:
lt_line type t_line,
lv_line type string,
lt_field type table of string.
open dataset 'XYZ' for input in text mode encoding default.
while sy-subrc = 0.
read dataset into lv_line.
split lv_line at '|' into lt_field.
append lt_field to lt_line.
endwhile.

Sharepoint Designer 2010 inserting blank lines

Sharepoint Designer (SP1) is intermittently inserting hundreds of thousands of rows as I am working with an .aspx document. This bug, which was first present in 2007, has been reported by many people over the years; it seems to remain in 2010.
Does anyone have a solution for this issue? Is there something in my page, which contains a bunch of xsltlistviews, that could be blowing up this file?
Thanks.

All --
FYI, here is a decent workaround to the problem of SPD 2013 (SharePoint Designer 2013) inserting blank lines into pages.
Here are the steps.
- Get CodeMaid (free) or similar coding-tool plugin/extension for Visual Studio 2013 (VS 2013) that can remove blank lines.
- Check out the file in SPD.
- From SPD, right click the file and choose open with, then choose VS.
- Run CodeMaid clean processing in VS, which will remove multiple consecutive blank lines.
- Save file in VS.
- Close file in VS.
- Check in file with SPD.
- Done.
It may seem like a lot of steps, and it is, and it odd the MS does not simply use the same code editor base for both VS and SPD, but using this workaround is actually pretty quick and easy, and easier still if you use the VS editor to code the files (instead
of the SPD editor) because the VS has way better code-folding and code-completion and code-digging anyway.
Just thought I would mention a (fairly) quick and easy way to workaround this SPD shortcoming.
HTH.
Thanks.

Insert statement in to internal table

I have an editable ALV LIST report with the check box to it. When the user checks the check box on the report and hits a push Button it should copy the row from the internal table and insert the row to the same internal table in the next line.
I had my code in this way,
 WHEN 'COPY'.
 LOOP AT t_output INTO wa_output.
 IF wa_output-chkbox = 'X'.
 wa_output-zactual = 0.
 wa_output-zqty = 0.
 INSERT wa_output INTO t_output INDEX sy-tabix.
 ENDIF.
 ENDLOOP.
However the problem was,
For e.g. let say I have only 3 rows in the internal table. So when the user selects the last, 3rd row and hits the push button the 3rd row copied and is inserted in the 3rd row. The user wanted the copied row in the next row, ie the 4th row.
SO I changed the above code as below and now it goes to an endless loop.
 WHEN 'COPY'.
 LOOP AT t_output INTO wa_output.
 IF wa_output-chkbox = 'X'.
 wa_output-zactual = 0.
 wa_output-zqty = 0.
 Sy-tabix = sy-tabix + 1.
 INSERT wa_output INTO t_output INDEX sy-tabix.
 ENDIF.
 ENDLOOP.
I dont want to use another internal table.
I hope I am clear.
Please suggest,
Ster.

Hi,
Change the code as follows.
data: lv_cnt type i.
 describe table t_output lines lv_cnt.
 LOOP AT t_output INTO wa_output where wa_output-chkbox = 'X'
 and wa_output-zactual = 0
 and wa_output-zqty = 0.
 lv_cnt = lv_cnt + 1.
 INSERT wa_output INTO t_output INDEX lv_cnt.
 ENDLOOP.

Hello,
Sort it_final by belnr.
loop at it_final.
on change of it_final-belnr.
clear temp_gsber.
clear temp_lifnr.
temp_belnr = it_final-belnr.
temp_gsber = it_final-gsber.
temp_lifnr = it_final-lifnr.
if it_final-gsber eq ' '.
it_final-gsber = temp_gsber.
endif.
if it_final-lifnr eq ' '.
it_final-lifnr = temp_lifnr.
endif.
modify it_final transporting gsber lifnr where belnr = temp_belnr.
endon.
endloop.

MODIFY ALL LINES IN INTERNAL TABLE

Hi,
How to modify more than one line in an internal table? I tried using update, failed as update is not for internal tables. Your help is appriciated .
thank you,
surya.

To change one or more lines using a condition, use the following statement:
MODIFY itab FROM wa TRANSPORTING f1 f2 ... WHERE cond.
This processes all of the lines that meet the logical condition cond. The logical expression cond can consist of more than one comparison. In each comparison, the first operand must be a component of the line structure. If the table lines are not structured, the first operand can also be the expression TABLE_LINE. The comparison then applies to the entire line. If the line type of the internal table contains object reference variables as component comp or if the entire line type is a reference variable, the attributes of the attr object to which the respective line reference points can be specified as comparison values using comp->attr or table_line->attr.
The work area wa, which must be compatible with the line type of the internal table, contains the new contents, which in turn will be assigned to the relevant table line using the TRANSPORTING addition. Unlike the above MODIFYstatement, the TRANSPORTING addition is not optional here. Furthermore, you can only modify the key fields of the internal table if it is a standard table. If at least one line is changed, the system sets sy-subrc to 0, otherwise to 4.
REPORT demo_int_tables_modify .
DATA: BEGIN OF line,
 col1 TYPE i,
 col2 TYPE i,
 END OF line.
DATA itab LIKE HASHED TABLE OF line WITH UNIQUE KEY col1.
DO 4 TIMES.
line-col1 = sy-index.
line-col2 = sy-index ** 2.
INSERT line INTO TABLE itab.
ENDDO.
line-col1 = 2.
line-col2 = 100.
MODIFY TABLE itab FROM line.
LOOP AT itab INTO line.
WRITE: / line-col1, line-col2.
ENDLOOP.
The list output is:
 1 1
 2 100
 3 9
 4 16
The program fills a hashed table with a list of square numbers. The MODIFY statement changes the line of the table in which the key field col1 has the value 2.
I hope it helps.
Best Regards,
Vibha
