Need to focus a particular field in OAF screen

Hi,
I have created a simple search page. Now based on the search criteria entered records will be displayed in tabular format. In Each row there are only two fields updatable. The screen has one ‘SUBMIT’ and one ‘SAVE’ button. Now while clicking on the save button it is not required that user enters values in all updatable fields. But while clicking on the submit button it is necessary that users enters values in all updatable fields. The button functionality is as follows
1. Clicking on Save button saves data into the underlying table(VO is created on that table).
2. Clicking on submit updates some other table by calling a PLSQL procedure.
Now my requirement is to put the cursor in that row where there is no value when user clicks on the submit button. If there are multiple rows which have null value in the updatable fields cursor will be placed in the first row where there is NULL value.
I am very new to OAF so i am not sure if there is any setcursor or setfocus method in OAF which i can use in my
processrequest()
Please help me out and thanks in advance……
Thanks

Hi Gaurav,
Thanks a lot for your quick response.But in my page all the records are being shown in a tabular format and in that table say 51 th row has a null value in its updatable field so when user clicks on submit button
1. i need to search which row has null value in its updatable field.
2. i need to place my cursor in that field.
Another issue i am facing with my search page
I have a date from and date to parameter in that page.Now i have created a LOV regoin based on a VO and in that VO i am retrieving both from date and to date by SQL query.
Now in the main page DATEfrom parameter i have attached the External LOV Regoin and in the LOV mapping i have created two mapping.
1.DateFromMap: LOV Region Item:StartDate
Return Item:Datefrom
Criteria Item:DateFrom
1.DateToMap: LOV Region Item:EndDate
Return Item:DateTo
Criteria Item:DateTo
The DateTo parameter is a messagestyledText type field and search Criteria is set to true.
Now In the LOV regoin when i am selecting any from date value the to date is being populated as per the LOV mapping but when i am clicking on 'GO' button the To Date is automatically being set to NULL.
Please help me to resolve these two issues.
Thanks

Need to add new Text Field on the Screen

Hi,
I am using Oracle 9 Designer and generating the web pages using web pl/sql language. After I generate the page, my screen looks like this:
Employee id: TextField
Employee Name: TextField
I want to add a comment"(Please enter characters Only" below the Employee ID like the following:
Employee id : TextField
(Please enter characters Only)
Employee Name: TextField
Can anybody help me how to add this in the designer form?
thanks in advance.

You can do this with an unbound item on a View Form. You cannot do it at all for an Insert Form. There is a work around but takes a little explaining for the Insert Form. You need to create a web page from the insert form html, modify it manually. I do it as a simple procedure so it is consistent with the rest of the application. Then all menus, links, etc. need to reference that page instead of the FormInsert procedure in the generated package.
There may be other work arounds. Without knowing more about your requirements, I can't say.

Hi,
Go to program RVPKMASS97.
Go inside INCLUDE rvpkmasspar.
(When you double click on the include a pop up screen will come up and in that select the RVPKMASS97)
Click on spiral icon there on the tool bar.
right click on the '
ENHANCEMENT-POINT RVPKMASSPAR_01 SPOTS ES_RVPKMASSPAR STATIC INCLUDE BOUND .' line and select enhancement-> create. and give some implementation name and text.

Validating field on selection screen

wht is the meaning of validation
how to validate a particular field on selection screen
suppose parameters:p_vkorg like vbak-vkorg.
how to validate p_vkorg.
pz give me coding

Hello pavan,
Validation means "checking whether the input which u are gining to the selection secreen is valid or not". means...
Lets take your example only...
parameters:p_vkorg like vbak-vkorg.
in selection screen you will give inout in that parameter....
users can give any input... lets suppose I'll give input as ABC... which is not in the table VBAK. No need to excute the code once we came to know that the input is not there in the table. So we will do validation like...
at selection-screen on p_vkorg.
select * from vbak where vkorg = p+vkorg. " This is the case with Parameter.
at selection-screen on p_vkorg.
Select * from vbak where vkorg = p+vkorg. " This is the case with Selct-option.
if the input that u r giving is present in the table... the above stmt will execute successfully, otherwise not.
You can make use of System variable SY-SUBRC and you can go ahead with ur coding...
Reward If Helpful

Need to change the LOV field based on checked box selection in OAF page

Dear ALL,
I have a requirement as below:
I have a custom OAF page having a lov field which is mandatory, a check box and a two text fields.
So based on LOV value selection i am defaulting two text field value automatically.
So my requirement is when user selects the check box automatically the LOV field should be non mandatory and user can insert in values to the lov field and text field and submit it.
SO basically based on check box field selection i need to make the lov field in such a way it should accept all the values what user enters instead of check the query added in VO behind the LOV.
Please suggest me some pointers to achieve this requirement.
Thanks
Deb

hi,

if ("checkevent".equals(pageContext.getParameter(EVENT_PARAM)))
                 HashMap hashMap = new HashMap();
                 String checkboxval=pageContext.getParameter("item2");
              hashMap.put("checkboxval",checkboxval);
                pageContext.setForwardURLToCurrentPage(hashMap ,
                true, // retain the AM
                OAWebBeanConstants.ADD_BREAD_CRUMB_NO,

OAMessageLovInputBean lovInputBean=(OAMessageLovInputBean)webBean.findIndexedChildRecursive("item3");

PM Reports: Need to find the sum of a particular field in the output.

Hello Experts,
                      I have an issue. I have developed the report to calculate the power per ton. It is PM module.
Input is : DATE & Measuring Point.
Output required is : For a particular date , What is the power consumed per ton.
Its is calculated by the formula Power consumed per day / Production.
I have multiple entries for production ( because different material are used ) per date and a single entery for power (because power is taken as total power consumed per day)
Hence im getting the output as
For example:
date                power            production         power/ton
01.03.2011      5000                    100                  50.00
01.03.2011      5000                      50                 100.00
01.03.2011      5000                      25                 200.00
01.03.2011      5000                      75                  66.66
The desired result is
date                power            production         power/ton
01.03.2011      5000                    250                  20.00
I need to sum the production field.
How can I achieve this ?
Please help.

Hello
Rotate the loop and use event so on change just clear the variable based date condition .
take 2 temp variable for summation
clearing the total and moving value on permanent variable means modifying the itab.
loop at .
*Clear
on change <datefield>.
modify itab from wa transporting <field name> .
clear <total field>.
endon.
*Total
t_prd = t_prd + production..
t_power = t_power + power .
endloop.

How to get the focus of particular UI Element

Hi All,
How to get the focus of particular UI Element in webdynpro Page,
I have a page where i am creating a ALV, I want to get that keyboard focus is on that element is there or not?
Can anyone please give some update?
Best regards,
Rohit

I would suggest try invoking REFRESH of ALV on the ON_CELL_ACTION event.
Below excerpt is from Thomas
The Events of inner UI elements are not exposed directly as they normally would be if they were standalone. Generally you can capture them using either the
ON_DATA_CHECK:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/c8/6c80dbedfe42d1a93f8e6df1d7244a/frameset.htm
This gets trigger for any press of ENTER, so it generally works like the Input Field onEnter.
You could also consider ON_CELL_ACTION:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/45/12093591152464e10000000a1553f7/frameset.htm
It is a higher level Event that encompasses both ON_DATA_CHECK and ON_CLICK.
if you want to capture & refresh on some hot key combination then refer to this thread
