How to get value less than 0 = 0

I am trying to get a formula to do two operation in one field something like:
form1.#subform[0].yes1.qn1::calculate - (JavaScript, client)
(p1-s1)
then if the value is less than "0" the the value = "0"
what I have so far is not working, any help is greatly appreciated.
if
(this.rawValue < 0) this.rawValue
= 0;
Thank you.

Srini,
Thanks for the reply, although I still cannot get this to work.
I changed the fields to numeric and it still is not working.

Yes - that is what it should be doing.
These are the steps you took to populate the table
1. You originally inserted ALL data into table 'drop_it' with no restriction on the PROD_DETAILS values.
create table drop_it as select * from mv_prod_search_det2;     2. Then you converted the PROD_DETAILS value to upper case. That has no effect on numbers or other non-alphabetic characters.
update drop_it set prod_details=upper(prod_details);3. Then you create a new table with only one partition using MAXVALUe
PROD_DETAILS VARCHAR2(1000 BYTE),
     SIGN VARCHAR2(42 BYTE)
PARTITION BY RANGE(PROD_DETAILS)
PARTITION MAX_VALUE VALUES LESS THAN (MAXVALUE)
);4. Then you populate the partitioned table by exchange. It now has the same data including the numeric data.
ALTER TABLE drop_it_p EXCHANGE PARTITION MAX_VALUE WITH TABLE drop_it WITH VALIDATION;     5. Then you split the one MAXVALUE partition into two partitions. One with data < 'B%' and one with the remaining data that sorts higher based on your character set.
ALTER TABLE DROP_IT_P
SPLIT PARTITION MAX_VALUE AT ('B%')
INTO (PARTITION p_a,
        PARTITION MAX_VALUE);     The split on 'B%' when creating partition p_a is equivalent to you 'WITH VALUES < 'B%'. Since PROD_DETAILS is a VARCHAR2 datatype that 'LESS THAN' comparison uses the character order based on your database character set and most, if not all, character sets have characters that sort lower than the uppercase alphabetic characters.
For example in the ASCII character set an uppercase 'A' is decimal 65 so 64 other characters (including the digitis 0-9) sort lower than 'A'.
http://www.asciitable.com/
As the doc you cited shows
>
•All partitions, except the first, have an implicit lower bound specified by the VALUES LESS THAN clause on the previous partition.
>
That 'first' partition has no lower bound so ALL data, including digits, that sort less than 'B%' will be in that partition.
>
please help me eliminate these rows

Either don't select the data to begin with or remove it using a simple DELETE query. Also you can do the case conversion when you select the data.
create table drop_it as select upper(prod_details) prod_details, sign from mv_prod_search_det2 where upper(prod_details >= 'A';Before you do that you should make sure you define the actual business rule you want to use to define the data you really want to keep and exclude.
Because most, if not all, character sets also have characters that sort HIGHER than the alphabetic characters. That ASCII table shows five of them. If you don't filter them out you will get data where the values start with those characters.
Even if you do filter them out there is nothing in what you posted that would prevent a user from inserting that data back into the table.
And, of course, there are characters that sort BETWEEN the lower and upper case alphabetics.
You need to determine what the allowable characters are in the PROD_DETAILS column and add code (e.g. check constraint or trigger) to make sure users can't enter data that includes those characters.

How to get value from list item

Hi all,
How to get value from list item?
I have a problem with the List Item object

How to get values/data stored in the database into a list-item.

how to get values/data stored in the database into a list-item.
i tried to make a list item without any values assigned to it...but i got the below error.
FRM-30191: No list items defined for required poplist.
or
FRM-32082: Invalid value for given item type.
List EMPNO
Item: EMPNO
Block: EMP
Form: MODULE5
FRM-30085: Unable to adjust form for output.
then according to some docs, i tried the the following for the trigger
when-new-form-instance
declare
     rg_name varchar2(40) := 'emp_rec';
     status number;
     groupid recordgroup;
     it_id item;
begin
     it_id := Find_Item('empno');
     groupid := create_group_from_query(rg_name, 'select empno from emp');
     status := populate_group(groupid);
     populate_list(it_id, groupid);
end;
but yet didnt work... :(
so how the heck do i get values fetched from the database table into the list item?

for list items you need to values in the record group, one is the shown value and one is the returned value.
Check out the online help for the populate_list built-in.
You'll need something like select ename,ename from emp as the record group query.

How to get value of URL parameter

Hi,
If an ABAP Web Dynpro URL looks like this: http://<server>:<port>/sap/bc/webdynpro/sap/zny_test1?sap-client=100&sap-language=EN, how to get value of the URL parameter sap-client at runtime in the application?
Thanks,
Nancy

The framework currently strips all the framework specific params.
Perhaps the will be made available in a future release. Thomas, any comments ?
However, I dont understand the requriement to know the sap-client URL value.
If your code is running, a user has successfully connected to system a therefore he has a session open and this session is associated with exactly 1 client at any point in time.
See SYSTEM VARAIBLE SY-MANDT.
this represents the client in which the users session is running and negates the need to see
sap-client URL value.

Phil.

How to get value of html combo box (i.e select) in jsp?

Hello,
I was just wondering how to get value of html combo box in jsp page. My code for combo box is:
<select name="combo" size="1">
<%
List<Project> projects = mgr.getProjects();
for(Project project : projects){
%>
<option value="<%= project.getId()%>"><%= project.getName()%></option>
<%
%>
</select>
I thought combo.value might give me the value, but it throws exception.
Any help is appreciated.
Thanks.

The combo does not exists in Java, but only in HTML. You have to submit the form containing the combo and then use request.getParameter("combo") to get it's value ;-)

How to get value of a textfield which has been set as Renderd false.

Hi all
how to get value of a TEXTFIELD which has been set as Renderd false.
i am getting the value of this textfield from an lov but dont want to show it to the user.
getting error as:
attribute xxxx required for view object yyyyy.
pls help
naveen

You can create item inside your LOV region, set the item style to formValue. You can associate this to a View Object field. It can also act as mirror of any other text input field.
FormValue can hold the value and will not be diaplyed to user. You can read value from it controller
example
OAFormValueBean orgValue = (OAFormValueBean)webBean.findChildRecursive("OrgIdFormVal");
Or you can read it fro the VO associated with this form value.

How to get Value of a item of first record when current record is second

How to get Value of a item of first record when current record is second in Form6i ?
get_item_instance_property dose not allow to get value.

Gerd,
You're right, there are several other triggers that must be coded, but I was responding to Steve's statement about Inserting or deleting records from the multi-record block. For the record, I use the following to manage a Record Group:
* When-New-Block-Instance - Initialize the RG
* block Post-Query - populate the RG
* When-Create-Record - add new record to RG
* When-Remove-Record - remove record from RG
* block When-New-Item-Instance - capture previous value of the item or row
* When-Validate-Item - Item specific Insert, Update, Delete of values in the RG
There are a few other places as well, but these are the minimum. It might seem like a lot of code, but then again, I don't use this solution for every multi-line block. Like all tools, you use the right tool for the job. :-)

How to get value by jstl?

select IEPort,seqNo,IEDate,trafMode from TImport
this is in hibernate hql
List queryResult = dao.getList(session, form);so in the list is not a bean but an Object, so in the Object do not hava attribute name, i don't know how to get value by JSTL in the jsp, who can help me

JSTL can figure out what the specific type of the Object is on its own. Just reference the attributes of your bean using the expression language like you would normally do. If you are uncertain print out the classname of the objects in the list like this:
${obj.class.name}where obj is an object from the list. This should print out the name of your beans if hibernate did its job properly. JSTL will know what properties these objects has even if you only pass it an Object reference.

Condition for excluding Sales value less than or equal to 0

Condition for excluding Sales value less than or equal to 0
Edited by: Arun Varadarajan on Apr 13, 2010 8:57 PM

Hello Naveen,
Thanks for quick reply. I have created condition greater than zero and executed report, i can able to eliminate rows with sales value <=0, but we have other columns in the report say Quantity, Backlog... when we run the report without condition the values which showed are same when we put it in active aslo.
After eliminating few rows which having some quantity value, that value should be deducted from the result of the quantity. I tried with applying apply to results opton, then also there is no change in the result value of the quantity.
Our requirement is to apply condition to eliminate rows which are sales value <=0 and same the result values of the columns should effect.
Is it possible in anyway, if yes please specify solution.
Thanks,
Venky
