How to catch event before retrieving data in table?

Hello
I use Oracle JDeveloper 11.1.1.2.0
I need to set parameters session (Package Vars) before any refresh my page (I retrieve data from views that use this vars).
For this reason I have created method setUserSessionParameters(int[] parameters) in AppModuleImpl.java and I am able to call it from my backing bean.
It's working fine, but I need to call it before any retrieving data in my tables.
May be, there is a usual way to catch event before retrieving data is started?
I'd call my method in that place. I think it would be perfectly well decision.

Hi,
you can define a PhaseListener method on the f:view component (it has pre and post properties for this). In the after RestoreView phase, you can access the binding container and call teh AM method to set the values. This way, before the page renders, the value is set

Hi,
1. Create Page Process.
2. Select Data Manipulation
3. In category select "Automated Row Fetch"
4. Specify process name, sequence, select "On Load - Before Header" in point.
5. Specify owner, table, primary key, and the primary key column(Item name contains primary key).
6. Create a process.
7. In each item select "Database Column" in "Source Type".

How to increase speed while retrieving data from tableand showing it in pop

Hi,
In one form ,I have used f9 key to retrieve data from table in oracle database . i.e. in any input field in my form, once I press f9 key, it execute JavaScript windows. Open command.
In that command, I called the servlet which retrieves nearly 7000 rows data from table and then it dispatch request to another jsp page which shows the related data in tabular form. The data may contain nearly 7000-8000 rows.
So when I press the f9 keys it takes around 10-12 second to open the page.
Is there any ways to open this pop up windows within 2-3 second once I hit the f9 keys.
Here with I am attaching hole code for servlet and jsp page.
Any suggestion is highly appreciated.
Thanks and Regards

First of all you will have to apply paging to show data in tables. and retrieve only those sets of data which are required. You will defnitely need to do lot of code for that. but i am hopeful, you will get some thing on net.
Second thing you can do is use AJAX. It will show your popup and will keep on loading data simultaneously. You can use JQuery and many others for that.

Problems with retrieving data from tables with 240 and more records

Hi,
I've been connecting to Oracle 11g Server (not sure exact version) using Oracle 10.1.0 Client and O10 Oracle 10g driver. Everything was ok.
I installed Oracle 11.2.0 Client and I started to have problems with retrieving data from tables.
First I used the same connection string, driver and so on (O10 Oracle 10g) then I tried ORA Oracle but with no luck. The result is like this:
I'm able to connect to database. I'm able to retrieve data but from small tables (e.g. with 110 records it works perfectly using both O10 and ORA drivers). When I try to retrieve data from tables with like 240 and more records retrieval simply hangs (nothing happens at all - no error, no timeout). Application seems to hang forever.
I'm using Powerbuilder to connect to Database (either PB10.5 using O10 driver or PB12 using ORA driver). I used DBTrace, so I see that query hangs on the first FETCH.
So for the retrievals that hang I have something like:
(3260008): BIND SELECT OUTPUT BUFFER (DataWindow):(DBI_SELBIND) (0.186 MS / 18978.709 MS)
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=1
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
(3260008): EXECUTE:(DBI_DW_EXECUTE) (192.982 MS / 19171.691 MS)
(3260008): FETCH NEXT:(DBI_FETCHNEXT)
and this is the last line,
while for retrievals that end, I have FETCH producing time, data in buffer and moving to the next Fetch until all data is retrieved
On the side note, I have no problems with retrieving data either by SQL Developer or DbVisualizer.
Problems started when I installed 11.2.0 Client. Even if I want to use 10.0.1 Client, the same problem occurs. So I guess something from 11.2.0 overrides 10.0.1 settings.
I will appreciate any comments/hints/help.
Thank you very much.

Installing 11g client changed something that even using old 10g client (which I still have installed) fails to work. The same problem occur no matter I'm using 10g or 11g client now. Powerbuilder hangs on retrieving tables with more than like 240 records.
Thanks.

How to save, update and retrieve data from two diffrent table

Hi,
I can save and retrieve data into an user defined SBO form from one database table only. How can I save retrieve and update records from two or more different tables in a single screen?
Regards,
Sudeshna.

Sudeshna,
Are these tables external to SAP Business One and do not have a Business Object? If there is a Business Object available such as if you were to enter an order, that order would use the Documents object which abstracts you, the programmer, from the underlying tables that need to be updated. If you are handling multiple business objects you would need to wrap the transaction with the StartTransaction - EndTransaction methods. This information is detailed in the SAP Business One SDK Help Center that comes with the SDK.

How to retrieve data from Table Control

Hi,
I am a Beginner to ABAP. I want to know how to fetch the selected rows from Screen table control.
Here is my scenario:
I am having one table control with selection field. Once i select some rows means the selected rows are going to be stored in one Internal Table.
If any body knows the thing means please reply me the logic as well as giving me some code sample.
Thankyou.

Hi Mithun,
Try to implement this code in your requirement.
There will be some button on your screen and after selecting some or all the records from the table control you must be pressing some button for collecting the selected rows from the table control too your internal table.
Put Fcode of that button in WHEN condition in this CASE.
CONSTANTS: kc_sel_flag TYPE char01    VALUE 'X'.
CASE sy-ucomm.
    WHEN kc_sel.
      PERFORM f_sel_desel USING kc_sel_flag.
ENDCASE.
FORM f_sel_desel
     USING    p_sel_desel TYPE c.
Set the value
wa_cond_type-z_sel = p_sel_desel.
Update the Itab.
MODIFY it_cond_type
         FROM wa_cond_type
         TRANSPORTING z_sel
         WHERE mandt EQ sy-mandt. "Where cond is only to specify all
ENDFORM.                    " f_sel_desel
After that all the selected records will be having 'X' in the internal table.

How to populate customer specific field data in table /SAPAPO/ORDFLDS

Dear Gurus,
I have explained in detail about the problem we face. I guess persons who has implemented enhancement: /SAPAPO/RRP_IO_COL in their system can help me out.
Background:
Purchase requisitions in APO is created by an idoc that comes from a legacy system using BAPI CALL FUNCTION 'BAPI_POSRVAPS_SAVEMULTI3'.
Business Requirement:
I have a business requirement where I need to populate an additional data 'Original delivery date' from the idoc during PR creation in Product view.
Development:
To achieve the above requirement, we are following the below procedure in our development system.
1. We are using enhancement: /SAPAPO/RRP_IO_COL, method: RRP_USEX_COLS_FILL_01 and RRP_USEX_COLS_GET_TEXT_01 to display an additional field 'Original delivery date' in /sapapo/rrp3 - elements view. This field is restricted to Purchase requisition (Order category: AG) only. We are planning to populate the additional data 'Original delivery date' in this customer specific field and store it in table: /SAPAPO/ORDFLDS at the time of PR creation.
2. Table: /SAPAPO/ORDFLDS is appended with the 'customer specific field'.
3. We couldnt find a document on how the data can be populated in table /SAPAPO/ORDFLDS.
4. How to polulate the live cache data in the table '/APAPO/ORDFLDS' ? ( i.e using connection parameter )?
Appreciate if you can throw me some light on this.
Thanks

Retrieve data on table with data type

How to find out the aligning Data dictionary table for a structure.

Hi
As the table controls are associated with strucures, the data input goes to the data dictionary table aligned to that structure. Is there any way we can find out the table related to that particular structure ?
Thanks,
Dhareppa

Hi,
The structure and its fields may be associated with multiple database tables.
You can try by where-used list of the structure/field and then you can look and determine the table by hit and try method.
Also as suggested above you can try get the SQL trace and then ypu can look for table associated behind the structure/fields I believe this is the best way to find the DB table.
Thanks,
Ravi

How to catch events from SAP

Hi everybody:
I'm trying to set an event in SAP and catch it from a .NET progam using the .NET Connector.
I have sow the function BP_EVENT_RISE but it seems it doesn't help enough.
We want to verify if the users have use an especific transaction inside SAP program. We have user exits created and we only need to indicate over the .NET program who is listening for some event.
How can I solve this?
We are not using Business Connector.
I will appreciate any suggestion.

The User Exit only reflects one step of exit performed by the user.
The events that i need to perform have the objetive to inform that some task have been performed inside SAP, a complete task, not only knowing that the user have finished his day work.
The idea it's to know that the user finished a new human resource registration, beyond it's well done, I need to know the number of the human resource.
On this point, I need to continue the registration in an automatic way over the security system (active directory), send an event to the person who have to regiter him over the corporate system and configure his mail (if needed).
I have look and evaluate the advise, but it dosen't solve my needs. I have to wait until my user finished his job (or ask him to exit) each time he register a new human resorce, that's not my idea.
Any other sugestion?. Thanks.

How to catch multi language's data in MSSQL and data isn't garbled

Hi everyone, I'm Taiwanese PHP developer, sorry for my poor English.
I have 3 language's data:Simplified Chinese,Traditional Chinese, and English in our mssql2012 database.
If I want to use ADODB to catch data,The Simplified Chinese and Traditional Chinese will be garbled.
I try to use mb_convert_encoding($data,
'UTF-8','BIG-5'),
the Traditional Chinese is ok, but Simplified Chinese is still garbled.
Do anyone have suggestion?
This is my output:
Array
[0] => Array
[0] => ZHS2
[1] => ?体中文
[2] => 123
[1] => Array
[0] => ZHS3
[1] => 翻?
[2] => 123
[2] => Array
[0] => ZHS
[1] => ?体中文
[2] => Chinese Simplified
[3] => Array
[0] => ZHT
[1] => 繁體中文
[2] => Chinese Traditional
[4] => Array
[0] => US
[1] => English
[2] => English US
Here is my code:
<?php
include('adodb5/adodb.inc.php');
function encoding_data($results){
foreach($results as $key1 => $result){
foreach ($result as $key2 => $arr_str){
if(is_integer($key2)){
//unset($results[$key1][$key2]);
//echo $key2."=>".$arr_str."<p />";
}else{
//echo $key2."=>".$arr_str."<p />";
$results[$key1][$key2] = mb_convert_encoding($arr_str, 'UTF-8','BIG-5');
$results[$key1][$key2] = mb_convert_encoding($arr_str, 'UTF-8', 'BIG-5');
return $results;
$sql = $_REQUEST['sql'];
$usedb = $_REQUEST['usedb'];
if($sql==""){
$sql = "select * from HCP";
if($usedb == ""){
$usedb ="oci8";
if($usedb == "mssql"){
$hostname = "Driver={SQL Server};Server=XXXX,XXXX;Database=XXXX;CharacterSet=UTF-8;UID=XXXX;PWD=XXXX";
//$port = XXXX;
$dbname = "XXXX";
$username = "XXXX";
$pw = "XXXX";
$mssqlconn = &ADONewConnection ('odbc_mssql');
//define connection string, specify database driver
$mssqlconn->Connect($hostname, $username, $pw , $dbname);
$mssqlconn->debug = false;
$results = $mssqlconn->GetArray($sql);
$results = encoding_data($results);
echo "<pre>",print_r($results),"</pre>";
print_r($usedb);
?>

Hi Yun Chen,
Not knowledgable on PHP programing, but as far as I know The BIG-5 is specific for traditional Chinese, so that's why you got garbled character for simplified Chinese.
As the Chinese character encoding wiki says, there're newer standards such as
GB18030 and
Unicode which have separate code points for both simplified and traditional characters. I believe this may be a good starting for you to make the conversion work.
Regarding your description, this is not some specific question on SQL Server. I would suggest you post your question on a dedicated PHP forum. It is more appropriate and more experts will help you.
If you have any question, feel free to let me know.
