Create dynamic table CALL METHOD cl_alv_table_create= create_dynamic_table

Hi gurus i have a problem i have created a dinamic internal table but the lenght of the internal table fields is 10 i need longer fields
here is my code thanks
data: begin of it_campos OCCURS 0,
            campo1(12) type c,
        END OF it_campos.
do n times.
       clear nocamptmp.
       add 1 to incont.
       CONDENSE incont NO-GAPS.
       cont = incont.
       CONCATENATE nocamp cont into nocamptmp.
       wa_campos-campo1 = nocamptmp.
       append wa_campos to it_campos.
    enddo .
    loop at it_campos into wa_campos.
      t_fieldcat_wa-col_pos = SY-TABIX.
      t_fieldcat_wa-fieldname = wa_campos-campo1.
      APPEND t_fieldcat_wa TO t_fieldcat.
    endloop .
CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
        it_fieldcatalog           = t_fieldcat
    IMPORTING
        ep_table                  = tabla
    EXCEPTIONS
        GENERATE_SUBPOOL_DIR_FULL = 1
    others                         = 2.
ASSIGN tabla->* TO <l_table>.
    CREATE DATA ep_line LIKE LINE OF <l_table>.
all is fine but the fields of <l_table> are char(10) and my data is longer than 10 how can i increase the lenght of the table fields
any idea thanks

Modify the fieldcatalog accordingly for e.g.,
LOOP AT it_campos INTO wa_campos.
t_fieldcat_wa-col_pos = sy-tabix.
t_fieldcat_wa-fieldname = wa_campos-campo1.
t_fieldcat_wa-inttype = 'C'. " Character Type
t_fieldcat_wa-intlen = '50'. "50 character length
APPEND t_fieldcat_wa TO t_fieldcat.
ENDLOOP .

Call method "cl_alv_table_create= create_dynamic_table"

Hi SDN Community,
Is it possible to create dynamic tables. I tried it by call method "cl_alv_table_create=>create_dynamic_table", but the "new_table" of output parameters is empty after the call is executed.
Please suggest.

Decimals on CALL METHOD cl_alv_table_create= create_dynamic_table

Hello experts:
I have a little problem, I want to create an ALV field with 4 decimales, it's a dinamic table, but when the alv report shows the fields it shows only 2 decimals, here the main code for explaining me better:
Here the code for create the field with decimals:
* Netpr
lv_cols = lv_cols + 1.
MOVE lv_cols TO wa_it_fldcat-col_pos.
MOVE 'NETPR'      TO wa_it_fldcat-fieldname.
MOVE 'Net Price' TO wa_it_fldcat-scrtext_l.
MOVE 'Net Price' TO wa_it_fldcat-scrtext_m.
MOVE 'Net Pr'     TO wa_it_fldcat-scrtext_s.
MOVE 'CURR'       TO wa_it_fldcat-datatype.
MOVE 'P'          TO wa_it_fldcat-inttype.
MOVE 11           TO wa_it_fldcat-intlen.
MOVE 4            TO wa_it_fldcat-decimals.
MOVE ''           TO wa_it_fldcat-ref_field.
MOVE ''           TO wa_it_fldcat-ref_table.
APPEND wa_it_fldcat TO t_fldcat.
After create more fields, here the code for create the dinamic ALV table:
* Create dynamic internal table and assign to FS
CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog = t_fldcat
    IMPORTING
      ep_table        = t_newtable.
ASSIGN t_newtable->* TO <t_dyntable>.
* Create dynamic work area and assign to FS
CREATE DATA t_newline LIKE LINE OF <t_dyntable>.
ASSIGN t_newline->* TO <fs_dyntable>.
After this method, the structure of the work area having the data type of the fields and all the atributes, the decimals of the NETPR fields just have 2 decimals =(
I hope my explanation it's clear.
Any help with this issue it's very welcome, thank you very much for your time.
Miriam

Hi
Xiaonan Hu is right: u need to delete the row where u transfer CURR as type:
* Netpr
lv_cols = lv_cols + 1.
MOVE lv_cols TO wa_it_fldcat-col_pos.
MOVE 'NETPR'      TO wa_it_fldcat-fieldname.
MOVE 'Net Price' TO wa_it_fldcat-scrtext_l.
MOVE 'Net Price' TO wa_it_fldcat-scrtext_m.
MOVE 'Net Pr'     TO wa_it_fldcat-scrtext_s.
*MOVE 'CURR'       TO wa_it_fldcat-datatype.
MOVE 'P'          TO wa_it_fldcat-inttype.
MOVE 11           TO wa_it_fldcat-intlen.
MOVE 4            TO wa_it_fldcat-decimals.
MOVE ''           TO wa_it_fldcat-ref_field.
MOVE ''           TO wa_it_fldcat-ref_table.
APPEND wa_it_fldcat TO t_fldcat.
If you transfer CURR, the method will defined a type p with 2 decimals by default, so it's useless to indicate the decimals in this case.
Infact the method calls the fm ALV_TABLE_CREATE, and here the abap code is:
- for CURR type:
elseif ls_fieldcat-datatype = 'CURR'.
        concatenate 'DATA:'
                    ls_fieldcat-fieldname
                    'TYPE'
                    ls_fieldcat-inttype
                    'DECIMALS 2.'
                    into lt_source-line separated by space.
- for P type
if ls_fieldcat-inttype = 'P' and not ls_fieldcat-decimals is
           initial.
          replace '.' with 'DECIMALS' into lt_source-line.
          concatenate lt_source-line ls_fieldcat-decimals '.' into
                      lt_source-line separated by space.
        endif.

Hi Sarbjeet,
The code is working fine, when i use in wddomodify view method without button click on first time.( I checked this by creating another component). But I am creating dynamic table when click on button(view contains one button initially), for this i created two attributes FLAG OF TYPE wdy_boolean and count of type int1. and in button action i write this code :
DATA lo_el_context TYPE REF TO if_wd_context_element.
    DATA ls_context TYPE wd_this->element_context.
    DATA lv_flag LIKE ls_context-flag.
get element via lead selection
    lo_el_context = wd_context->get_element( ).
get single attribute
    lo_el_context->set_attribute(
        name = `FLAG`
        value = abap_true ).
DATA lv_count LIKE ls_context-count.
get element via lead selection
lo_el_context = wd_context->get_element( ).
get single attribute
lo_el_context->get_attribute(
    EXPORTING
      name = `COUNT`
    IMPORTING
      value = lv_count ).
lv_count = lv_count + 1.
lo_el_context->set_attribute(
    EXPORTING
      name = `COUNT`
      value = lv_count ).
and in wddomodify view method following code..
Method WDDOMODIFYVIEW
DATA lo_el_context TYPE REF TO if_wd_context_element.
DATA ls_context TYPE wd_this->element_context.
DATA lv_flag LIKE ls_context-flag.

Problem with editable combo box and creating dynamic table values using js

Hai
I have used jquery.jec.js to make my dropdown list as editable... I need to create dynamic table values on the onChange event of dropdown using javascript.
Now am facing the problem in it...
I am getting duplicate rows in the table... think(assumption) this jquery.jec.js is calling the dropdown again creating duplicate values...
Please help me out.... Any help is appreciable... Thanks in advance

Thanks elOpalo, for your valuable response....
I have found the correct way of doing.
Before i had my code like this,
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>test</title>
<script type="text/javascript" src="js/jquery-latest.js"></script>
<script type="text/javascript" src="js/jquery.jec.js"></script>
<script type="text/javascript">
$(function(){
$('#list').jec();
function giveAlert(){
alert('hello');
</script>
</head>
<body>
<form>
Combo Box:
<select id="list" name="list" onChange="giveAlert();">
<option value="1">one</option>
<option value="2">two</option>
</select>
</form>
</body>
</html>
Now i have changed as the following,
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>test</title>
<script type="text/javascript" src="js/jquery-latest.js"></script>
<script type="text/javascript" src="js/jquery.jec.js"></script>
<script type="text/javascript">
$(function(){
$('select.combo').jec();
$('select.combo')
.change(function() {
alert($(this).val());
}).change();
</script>
</head>
<body>
<form>
<table>
<tr>
<td>Combo Box:</td>
<td><select class="combo"><option value="b">banana</option><option value="a">apple</option></select></td>
</tr>
</table>
</form>
</body>
</html>
The problem is with the function i have called on the onChange Event.. Now i have defined it inside the jquery function of dropdown to make it as editable...

Create dynamic table using pojo data control

What are the options we can in order to create dynamic table columns based on pojo data control?
We have a class A and there are some attributes say A.x, A.y, A.z
Within class A, we have a collection of class B and has attribute say B.k
Within class A, we have a collection of class C and has attribute say C.j
Every instance of class A has same number of instances of class B
Every instance of class A has same number of instances of class C
We would like to display a table like this
A.x, A.y, A.z, [B.k, B.k, ...], [C.j, C.j, ...]
How should we do that?
Thanks

This tells you more about the vendor than the vendor would like you to know ......
Like the vendor that told me their product would work with an oracle database, but they preferred SQL Server because "oracle doesn't perform will with more than 5 concurrent connections". Fortunately we were still in product evaluation and I was able to get them cut from the short list.
After seeing all your replies, now, I have contacted them asking for alternatives and explanations.
Anyway, Thank You to everyone of you.

How to create dynamic event handler methods?

Hello!
Is it possible to create dynamic event handler methods in the views of WDC and then subscribe to an event of another WD component completely dynamically.
Many thanks,
Smitha.

By first realising AJAX is not Java but JavaScript and then reading a tutorial on JavaScript DOM manipulation and then by reading a tutorial on AJAX and then by applying your knowledge and then in the end by integrating it in your JSP.

How to create Dynamic Table Control

Hi
How to create Dynamic Table control , The field names and values to be displayed in table control are to be fetched from Add-on Tables.
Regards
Prasath

Hi Jonathan,
Actually the columns to be displayed are not constant . It will be increased based on the database values, Anyhow it will not exceed 100.
Please confirm my understanding.
1. In this case I have to create 100 custom columns and make it visible / invisible based on my requirement and I can set the title at runtime.
2. How can i assosicate / reassociate the datadictionary reference for the columns that i use. Because I need to show the search help values for the
dynamic columns.
Your opinion on this will be helpful.
Regards
Prasath

Table Type in cl_alv_table_create= create_dynamic_table

Hi guys,
The method create_dynamic_table from cl_alv_table_create has as exporting parameter a fielcatalog table. I want to insert a table type in this table, basically the field INTTYPE from LVC_S_FCAT can do that if u put the value 'h' in it. But I notice, that in method implementations all the cases are considered:
C
Character String
N
Character String with Digits Only
D
Date (Date: YYYYMMDD)
T
Time (Time: HHMMSS)
X
Byte Sequence (heXadecimal)
I
Integer number (4-byte integer with sign)
b
1-byte integer, integer number <= 254
s
2-byte integer, only for length field before LCHR or LRAW
P
Packed number
F
Floating point number to accuracy of 8 bytes
and other, but not 'h'.
Does anybody knows how create a dynamic table with a table type inside ? The table type has the structure from data dictionary lvc_t_scol.
Ionut.

cl_alv_table_create=>create_dynamic_table( ) is no longer recommended to build dynamic tables.
RTTC classes are very intuitive and quite easy to maintain.

Create dynamic table

Hi
I am new to Javascript. Anyone has a standard program to create a dynamic table after getting the input from the user. The number of columns would be 2 and the number of rows depend upon the user input. And the number of rows should not exceed 4. I tried some codes from web but does not seem to work for me. Thanks.

Sorry, new to JSP. I tried as follows. My basic idea is get the input from the user and generate table according to that.

Procedure for creating dynamic table

Hi! I'm having a problem with creating a table with the help of procedure. The thing is, I want to pass an (possibly an array of) unknown amount of values - column names, types - to the procedure, that I defined, and then be able to create a (temporary) table with the received data. Possible? Maybe you could give me some hints - any help appreciated.

899749 wrote:
Yes, not literally there are million fields, of course :) What I was trying to say -> there are too much fields to create a hidden field array each time, and honestly I don't like this because of content availability through source code.Statement does not make sense.
If there are too many "fields" (databases have tables and rows and columns - not fields), then how does introducing a new database table reduce these? It is far simpler to only select the rows required, the columns needed for display, and building a "field array" using that - assuming that your definition of such an array matches mine...
Besides the saneness and logic of using dynamic tables, there are performance considerations. The slowest and most expensive database operation is I/O.
So what is your justification to spend a lot of I/O on duplicating existing data in the database? Why read data from tables to create so-called dynamic tables? Is that the best spend of database resources?
Don't know what forms you were talking about - the idea is to possibly use some programming (like php) + html to create a dynamic form. That's why I need a dynamic temporary table to pass the content around (no sessions, please).Forms are typically not dynamic. You do not point code at some arbitrary table structure and say "+form instantiate thyself+". This code will not understand the business rules and validation rules for properly displaying a data entry form for that entity, and applying the rules and logic for processing entered data and storing that in the table.
Forms are usually (almost always) coded as static - the entry fields are known at design time. The validation rules are known. The business logic to apply is known.
That begs the question as to not only what you are trying to do (it does not make sense!), but also why? What are the business requirements that need to be met?

How to create dynamic tables in jsp page

Hi,
Iwant to create a table with 8 rows.each row will have two select boxes and one text box.besides i have add button.intially the screen shows only one row.if user clicks on add button then another row is added.like this upto 8 rows.
how can solve this problem..
regards,

Hi I am not a big programmer but i can suggest a method to u
try something like this..
this could be quite adjusted in html page itself.....
<html>
<head>
<script language="javascript">
var count=1
fucntion addRow(){
if(count<8){
count=count+1
row.innerHTML=row.innerHTML+"<tr><td><input type='text' name="+count+"></td><td><input type='button' onclick=addRow() value='Add' name='add'></td></tr>"
else if(count==8){
row.innerHTML=row.innerHTML+"<tr><td><input type='text' name="+count+"></td><td></td></tr>"
</script >
</head>
<body>
<form action='Myservlet" method='post'>
<table>
<div name='row' name='row'><tr><td><input type='text' name=1></td><td><input type='button' onclick=addRow() value='Add' name='add'></td></tr></div>
</table>
</form>
</body>
</html>
I believe it could be quite adjusted @ client side itself.... as per your description...
