How to access hidden fields in a table

hi
what is the use of hidden fields in a table, ie. some fields doesn't visible in the field list of a table. but the fileds will be visible if u display its contents.
for example in table t518A the text field is not visible in the field list. But it will be visible if display its contents. can any one of u please help me out how to access those fields.
regards
sri

Hi Srivallika,
The table T518A has a text table called T518B. You can have a look at this table by:-
1. GOTO SE11 and display table T518A.
2. GOTO menu GOTO -> TEXT table. It gives the text table for the given table. Here its is T518B.
A Text table is table with same key fields as the main table with another extra Language key TYPE SPRAS. This table is related to the main table. Hence to access the extra text fields, you can use the TEXT table :).
Thanks and regards,
Ravi.

How to pass hidden field values on a click of a table row

hi all,
href = "bookAndNonBook.do"
I am very new to struts. I have created a table using displaytable tag which displays results in a tabular format. In addtion, i have a hidden field (prodType), the table rows are getting highlighted when i get my mouse on a particular row.
Following is the code from the results.jsp file
<body
onload="addRowHandlers('row', 'rowMouseOver')"
bgcolor="#FFFFFF" text="#000000" leftmargin="100" topmargin="50"
marginwidth="" marginheight="" rightmargin="30">
<html:form action="/bookAndNonBook" method="post">
<display:table name="sessionScope.productSearchList" id="row"
sort="list" export="true" defaultsort="1" defaultorder="ascending"
pagesize="15" decorator="org.displaytag.decorator.TotalTableDecorator"
class="dataTable">
<display:column property="prodType" title="ProdType" class="prodType"
headerClass="prodType" media="html" />
<display:column title="Title" property="titleName" sortable="true"
class="title" headerClass="title" />
</display:table>
</html:form>
</BODY>
I am calling a funtion addRowHandlers which passes the table id (which is row) and the rowMouseover for highlighting the rows on mouse over.
the code for function addRowHandlers is
function addRowHandlers(tableId, rowClassName) {
var previousClass = null;
var table = document.getElementById(tableId);
var rows = table.getElementsByTagName("tr");
for (i = 1; i < rows.length; i++) {
rows.onmouseover = function () {
previousClass = this.className;
this.className = this.className + " " + rowClassName ;
this.style.cursor="hand";
rows.onmouseout = function () {
this.className = previousClass;
this.style.cursor='';
rows.onclick = function (){
var cell = this.getElementsByTagName("td")[0];
var ProdType = cell.innerHTML;
alert("value of prodType = " + ProdType);
when i run the above code and click on a particular row it returns me the value in the hidden field i.e. prodType for that particular row
Now where i am having problem is i want that on the basis of prodType my jsp file should call different actions for different prodType as returned....somwhat a function like this
function submitProduct(prodType) {
if(prodType == "BK")
resultsForm.action = "/bookProduct.do";
else if(prodType == "NB")
resultsForm.action = "/nonbookProduct.do";
but i am unable to figure out that how do i this..
Any help will be really appreciated
Thanks

can you please suggest some good struts forums where i can post my question

How to open hidden field in PO

Hi,
How to open hidden field info record as edit mode and delete. initially we used info records now we are not using info records, some of the po's already captured info record numbers now when we try to close this PO its hitting error message info record doent exist. when i see in table i can find record number but actually this record was deleted now how to put back hidden field to edit mode and delete this info record.
Thanks in advance.

Hi,
If the PO was created against that Info record you cannot just open up the field and delete the Info record reference. There is integration between the two records and if you look at the previous POs on a non-deleted info record you will see the link that way too.
So you cannot break the link like this.
Surely you didn't physically delete the info records? They should have been flagged as deleted and if that was not enough then they should have been archived (in which case you shouldn't be getting this mnessage).
Have you tried changing the message from an error to a warning (or nothing)? I doubt if this will work for the same reasons as above but it would be worth trying first.

Hi,
Hi ,
You will need to group that radiobuttons so that SAP knows they are linked together. To do this using the grahical layout editor simply select all the radiobuttons and then right click on them, Now choose define group. Once you have done this you should not need any of the "clear" or "='X'" statements SAP should control it all for you.
hope this helps

How to access a field of a structure with a field symbol?

Dear all,
Currently I'm trying to access the fields of a structure (called "ls_tbl") dynamicly. The code looks as follows (of course the field symbols are defined correctly ;-):
    ASSIGN lv_f1 TO <lv_f1>.
    ASSIGN lv_f2 TO <lv_f2>.
    lv_pp = ls_tbl-(<lv_f1>).
    lv_pt = ls_tbl-(<lv_f2>).
Unfortunatly I get the following error message:
<<The data object "LS_TBL" does not have a component called "".>>
I really do not understand why ABAP is trying to interpret the field symbol name as a string. Does anybody have a clue how to access the field of ls_tbl with the help of a field symbol?
Many thanks!!!

Hi ,
Please check the below sample code .
data : begin of st_table,
            myfiledname type c value '1',
            myfiledname1 type c value '2',
       end of st_table .
data : lv_filedname(11) type c value 'MYFILEDNAME'
filed-symbols : <fs> type any,
                <fs_table> type any.
assign st_table to <fs_table>.
Assign lv_filedname to <fs> .
assign component <fs> of structure <fs_table> to lv_pp.

How to access a field of an data source w/o binding a form field to it

Hi
This is a query regarding ADOBE print form.
How to access a record field (of an data source.... typical multi row records) where the record is bound to a subform.
Data is something like
(I have used abap parlance for understanding)
data : begin of data_tab occurs 0,
field1 type .....,
field2 type .....,
fieldm type .....,
fieldn type .....,
end of data_tab.
Subform is bound to
$.DATA_TAB.DATA[*]
How to access field1, field2,...... etc without creating subform fields and binding them to field1, field2, .... fieldn.
I know normal approach is to define subform fields and then bind it to $.field1, $.field2 etc
In the calculate event of a field bound to $.fieldm I have tried the following expressions to get the value of column fieldn of the same record but none of them worked.... Note that if I bind the field using $.fieldn data is displayed properly in the print form.
$record.data_tab.fieldn.value
$record.data_tab.data[*].fieldn.value
$record.data_tab.data.fieldn.value
$record.data_tab.fieldn.value
Otherwise I would have to define hidden fields just to use these column values in the event script even though these value are not to be displayed in the ADOBE print form.
Regards
Abapper

I can't remember the exact sentence, but do a little search, as that is a common question in this forum....
How about:
$record.data_tab.data[1].fieldn.value
$record.data_tab.data[2].fieldn.value
$record.data_tab.data[2].fieldn.value
$record.data_tab.data[N].fieldn.value
Cheers.

How to access dynamic fields in a field symbol

hi
how do i access the dynamic fields created in side a field-symbol....
wht i mean is i have a table, whose workarea i assign to field symbol. but this table is runtime, altough i have debugged and found the values in this table, I want to accees the field symbol in a generic way.
say the table has 3 fields now fld1 fld2 and fld3 so i want to access the field symbol <fs> as <fs>-(name) where name can be anything fld1 or fld2 whichever i assign....
thanks. Let me know if you have any further questions.

Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object. The data object to which a field symbol points is assigned to it after it has been declared in the program.
Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to a field symbol before you can address it in a program.
Field symbols are similar to de-referenced pointers in the C programming language (that is, pointers to which the content operator * is applied). In ABAP, data references represent a real equivalent to pointers in the sense of variables that contain a memory address and can be used without the contents operator.
All operations programmed with field symbols are applied to the field assigned to it. A MOVE statement between two field symbols, for example, assigns the contents of the field assigned to another source field symbol to the field assigned to the target field symbol. The field symbols themselves point to the same fields after the MOVE statement as they did before the MOVEstatement.
You can create field symbols either without or with type specifications. If you do not specify a type, the field symbol inherits all of the technical attributes of the field assigned to it. If you do specify a type, the system checks during the field assignment whether the assigned field matches the type of field symbol.
Field symbols provide greater flexibility when you address data objects:
·        You can assign one field symbol to another, which allows you to address subfields.
·        Assignments to field symbols may extend beyond field boundaries. This allows you to address regular sequences of fields in memory efficiently.
·        You can also force a field symbol to take different technical properties than those of the field assigned to it (casting).
The flexibility of field symbols provides elegant solutions to certain problems. On the other hand, it does mean that errors can easily occur. Since fields are not assigned to field symbols until runtime, the effectiveness of syntax and security checks is very limited for operations involving field symbols. This can lead to runtime errors or incorrect data assignments.
While runtime errors indicate an obvious problem, incorrect data assignments are dangerous because they can be very difficult to detect. For this reason, you should only use field symbols if you cannot achieve the same result using other ABAP statements.
For example, you may want to process part of a string where the offset and length depend on the contents of the field. You could use field symbols in this case. The MOVE statement (with your own auxiliary variables, if required) is much safer than using field symbols, since it cannot address memory beyond the boundary of a field. However, field symbols may improve performance in some cases.
To declare a field symbol, use the statement
FIELD-SYMBOLS .
For field symbols, the angle brackets are part of the syntax. They identify field symbols in the program code.
If you do not specify any additions, the field symbol.
in a static ASSIGN and:
ASSIGN (dobj) TO from the second loop pass onwards.

An yet you keep getting suggestions of how to set the focus. I looked through the API documentation and I don't see anything that would suggest you can request to see where the current focus is. Perhaps someone might still come along with a solution, but my hopes wouldn't be too high at this point. I can pass the requirement onto Product Definition, as the use case does seem interesting. Perhaps it is something we have even considered in the past.
But for now, there might be a better way to solve your problem. It will probably mean redesign the interaction. What exactly are your requirements? Do you need to be able to get the data in a particular cell of table when a button is clicked? Just throwing out some ideas here, but maybe just use the lead selection to select the row, but then have a button choice to choose the action associated with the column you want. A hack for sure - but it might work. Also it doesn't help you right now, but in the near future update to NetWeaver 7.0, WDA does have a onColSelect event for the table.

How to read the field value from Table Control

Hello Experts,
I am creating my first Table Control Screen. Basically I have to create a screen (102) with a table control which has 2 fields: A_QTY, B_QTY and 2 Buttons: SAVE, EXIT.
When Clicked on 'SAVE' the data (MATNR) from a previous screen (101) and the data (A_QTY, B_QTY) from the new screen (102) should be saved into a Z-table.
Internal table t_data has 3 fields.
MATNR
A_QTY
B_QTY.
Table Control TC_RACK was declared like this:
controls tc_rack type tableview using screen 0102.
I/0 Fields:
A_QTY type ZQTY.
B_QTY type ZQTY.
The screen Flow Logic:
process before output.
module status_0102.
loop at t_data into w_data with control tc_rack.
endloop.
process after input.
module exit_0102 at exit-command.
loop at tc_rack.
endloop.
module user_command_0102.
module status_0102output.
set pf-status 'STATUS_102'.
set titlebar 'TITLE_102'.
describe table t_rack lines tc_rack-lines.
endmodule.                 "status_0102 output
process after input.
module user_command_0615 input.
case ok_code.
   when 'SAVE_RK'.
   when others.
endcase.
endmodule.                 "user_command_0102 input
Now for eg, when the users enter values for A_QTY and B_QTY like this:
A_QTY     B_QTY
1000         2000
3000         4000
How can I read these values and pass them to T_DATA so that I can save it into Z-table?
I greatly appreciate your help.
I've gone through some previously posted threads and could not understand because my knowledge in this area is preliminary.
Thanks a lot.
Could you please let me know
Edited by: dev a on Jan 13, 2010 2:46 PM

Hi dev a
You should use
DATA: lv_name(30) TYPE c.
FIELD-SYMBOLS: <QTY> type ZQTY.
GET CURSOR FIELD lv_name.   "Get the field name in table control
check sy-subrc = 0.
assign (lv_name) to <QTY>. "Here you get the value in <QTY>
check sy-subrc = 0.
Also use <your table control>-current_line to get the table index uo're currently on.
Hint: Do not use GET CURSOR LINE if you want to get table index since this gives you the line relative to dialog screen
Good luck

How to make screen field enable when table control gives an error

Hi,
I had a scneario like when table control data wrong then one parameter of the screen should be enabled for the input, i knew that screen-name will not work since it will have always table control fields only when table control gives an error.
How to make the other parameter enable when table control throws an error.
Regards,
Jaya

Hi Gobi,
Thanks for your response, but issue is - how to make other screen fields enable when there was an error in the table control data.
For table control - lets say we will use the code as i mentioned above.i am sure that we cant write the code for field enable in between loop & endloop.
as you said if we right outside the loop-endloop, the module wont be triggered when table control throws an error, because that statement was not there in the loop-endloop.
please let me know if you need any more information on the issue. I hope there is alternative for this in SAP.
Thanks
Jaya

How to set hidden field value in form?

I've encountered a problem while developing a forum using JSF. See this code:
<h:form id="commmentForm" formName="commentForm" >
     <h:input_hidden id="pageId" valueRef="CommentBean.pageId" value="${article.id}"/>
     <h:input_text id="userName" valueRef="CommentBean.userName"/>
     <h:input_text id="userEmail" valueRef="CommentBean.userEmail"/>
     <h:input_text id="userURL" valueRef="CommentBean.userURL"/>
     <h:input_textarea id="content" valueRef="CommentBean.content"/>
     <h:command_button id="submit" label="Leave A Comment" commandName="submit" actionRef="CommentBean.createAction" />
</h:form>
I was trying to specify a hidden field that represents the unique ID number of the current article using <h:input_hidden> tag above. But RI complains that runtime expression is not permitted in 'value' attribute. So I set the attribute 'value' to arbitrary number such as '2', but it seems that CommentBean.pageId is still null.
So the question is:
1. Why can't I use EL in JSF tags attributes?
2. How can I resolve my problem mentioned above?
Thanks very much in advance!

To solve the problem, you have to use two hiddenfields, say:
<h:input_hidden id="pageId"valueRef="CommentBean.pageId" />
<h:input_hidden id="articleId" valueRef="article.id"/>
I want to set the value of CommentBean.pageId to
${article.id} (article is not a managed bean) and to
let CommentBean.createAction insert a database row
whose page_id column is ${article.id}, so I think the
tags you suggested won't work for me.Why can't you interrogate your ComponentBean for its pageId property during your invoke() method? By the time your invoke() method is called, the value from the hidden field will have been pushed to the model, so this should be no problem. You could do Application.getValueBinding("ComponentBean.pageId").getValue() to do so.
