Hi Raj
Generally we Call Set Table for First Display in the PBo part. So that there itself you need to trigger Top of page envent.
Please check the flow below. This is a good standard we adapted from SAP Standard.
MODULE STATUS_0100 OUTPUT.
SET PF-STATUS 'S_100'.
SET TITLEBAR 'T_100'.
Exclude the Unwanted Tool bar functions in the ALV
Perform EXCLUDE_TOOL_BAR_FUNCTIONS Changing PT_EXCLUDE.
Fill The Field Catalog for ALV View
Perform FILL_FLDCATALOG Changing TB_FCAT.
Fill the Top Of Page Event
Perform TOP_OF_PAGE_ALV.
Form to Fill the Color / Highlight the Line
Perform FILL_COLOR.
Display Data
Perform DISPLAY_ALV.
ENDMODULE. " STATUS_0100 OUTPUT
Hope this helps

How to get number of pages in word document

I am developing an OCR application where I need to get number of pages of word documents. I am currently assuming that each page consists of 46 lines but some how, I am not getting convinced with this logic. Is there any simplest way to get this information?
Let me tell you that in the OCR system I am converting tiff iamges to .txt file and again reading txt file and counting number of pages based on number of lines.
regards,
Ranjan

The number of pages depends on the font size, length of each line and any page break in between.
You could just say, one page per 46 lines, it depends on how accurate you must be.
Why not count the number of pages you scanned?

How to get the last page SAP Script form

How to get the last page SAP Script form.
I want to print a specific information in the last page of SAP form (Script). Please tell me how to get the last page number.

Hi
You have to check the system variable &NEXTPAGE&, if it's 0 it means you're in the last page.
From SAP Help:
This symbol is used to print the number of the following page. The output format is the same as with &PAGE& .
Note that on the last page of the output, in each window that is not of type MAIN, &NEXTPAGE& has the value 0.
/: IF &NEXTPAGE& = '0'
Last page
/: ENDIF

How to get number of rows return in SELECT query

i'm very new in java, i have a question:
- How to get number of rows return in SELECT query?
(i use SQL Server 2000 Driver for JDBC and everything are done, i only want to know problems above)
Thanks.

make the result set scroll insensitve, do rs.last(), get the row num, and call rs.beforeFirst(), then you can process the result set like you currently do.
         String sql = "select * from testing";
         PreparedStatement ps =
          con.prepareStatement(sql,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
         ResultSet rs = ps.executeQuery();
         rs.last();
         System.out.println("Row count = " + rs.getRow());
         rs.beforeFirst();~Tim
NOTE: Ugly, but does the trick.

How to get the current page URL

How to get the current page url for the page item.
Any steps should be help ful
Thanks & Regards

I'm not 100% clear on what the requirement is from the description, however it does sound like you are making things unnecessarily complicated.
If you want permanent/ID-independent links then use application and page aliases.
so here we used to display the url like this: <tt>{noformat}http://81.131.254.171:8080/apex/f?p=122{noformat}</tt>
Do you mean that the URL is displayed like that? If so that doesn't seem particularly helpful. How is anyone supposed to know what it is?
There are many ways to provide links in APEX—including lists and nav bars.
Where the link is to another resource located on the same server (such as another page in the same app, or a different app in the workspace), relative addressing can be used, making it unecessary to include scheme, domain and port information in the URL. For example, if the page to be linked to has a page alias <tt>ABOUT</tt> in an application with alias <tt>UNITY</tt>, and the apps share an authentication scheme/cookie to permit shared sessions, then the link URL is simply
f?p=UNITY:ABOUT:&APP_SESSION.

How to get the Empty page in Webi report

Hi,
I have to insert the charts in the report but i don't have the space to insert the charts in same page so i need one more page how to get the blank page in report
thanks,

turn your report from Page Layout to Draft Mode. Than you will be able to insert chart in it.
You can view Web Intelligence reports in different modes depending on how you want to work with data and how you want the data to appear.
1. In Web Intelligence Interactive, select the report tab of the report you want to view.
2. Click the arrow next to the View button on the main toolbar above the report.
3. Select the viewing mode.
4. In the Java Report Panel or Web Intelligence Rich Client, use Switch Page/Quick Display on the Reporting toolbar to alternate between Page mode and Quick Display mode.

How i get number of record in repet frame?

Hi,
How i get number of record in repet frame?

Jomar

Jomar,
you can use Summary Columns in the Data Modell. Create them on group higher that your wished group (so on the pane for an first group of a query), use as Source the primary column and as reset at the group, where the summary column is located.
If you hide some instances via format triggers, that you could use a counter inside the format triggers to count the rows.

Get number of pages of adobe form before printing

Dear Experts,
I want to get number of pages adobe form will print before printing the form.
Please suggest.

Hello Sagar,
Without executing the generated Function Module, it is not possible to get the page count of a form in driver program because the generated FM itself is responsible to execute the whole layout and determine the number of pages in the PDF output. The below screenshot shows the number of pages in the structure /1BCDWB/FORMOUTPUT of generated FM after the generated FM is executed successfully.
I really don't know why you need the number of pages before calling the generated FM. But if you still need it, then you might need to call the whole FM cycle twice( FP_JOB_OPEN , Generated FM, and FP_JOB_CLOSE ).
1) First time while calling the FM FP_JOB_OPEN, you need to modify the contents of SFPOUTPUTPARAMS structure. Send the blank values in fields GETPDF, REQNEW and REQIMM, and send the "X" in fields NOPREVIEW, NOPRINT and NOARCHIVE and 000 in field COPIES.
The reason for doing this is, we do not want actual PDF output. We only want to determine the number of pages.
2) Now execute the generated FM . You will get the number of pages in the structure /1BCDWB/FORMOUTPUT-PAGES as shown in screenshot above.
3) Now call the FM FP_JOB_CLOSE as usual.
4) Again call the FM FP_JOB_OPEN. This time you again need to modify the contents of SFPOUTPUTPARAMS structure reversely. Send the "X" in fields GETPDF, REQNEW and REQIMM, and send the blank values in fields NOPREVIEW, NOPRINT and NOARCHIVE and 001 in field COPIES.
This time we need the actual PDF output.
5) Now do the required processing with previously fetched number of pages before calling the generated FM.
6) Now call the FM FP_JOB_CLOSE as usual.
