Hierarchical data display in POWL result table

Hi All,
We have a Product BO where each Product is associated with (0..n) product groups and (1..n) distribution chain data. We have a powl for this Product search where we display results for:
Product based on predelivered/custom queries and quick search criteria. Now say in the result of a particlualr query we have 5 Product(s). In each row we have columns called Product grp and sales org, where we need to show (0..n) prod grps and (1..n) distribution chain attached to each Product. Can we show this data using nested Column, tree in column, Nested ALV in powl resultset??
For this, I want to create hierarchy list in POWL. Can anybody tell me how to do that? Are there any configuration settings for this?
Thanks, Ashish

Hi Ashish,
Please use the Grouping and Sub Grouping options with ALV settings.
Goto results ALV table settings. In that you have tab for Grouping. You can group and Sub Group Columns.
Also you can define aggregations on the Grouped columns.
Hope this will be helpful.
Thanks,
Anand

Jsp data display as a result of a button click

i have a textfield in a jsp along with a SEARCH button. the search button searches the database for the existence of the value entered in the textfield.
how should i code so that at the click of search button the dbase is searched (for the entered value in textfield).
the dbase should be searchedonly after the click of search button.
i wud also like to display the searched value as a table data next to the button. how shud i code it. i coded search logic using a function which is in a javascript. but the function is executing before the press of the search button.
i'm new to JSPs. please help.. thanks.

It's covered by every decent JSP/Servlet book/tutorial. With other words, this is too trivial and it proves that you really know nothing about it at all. I then highly recommend to take time first to go through a decent book/tutorial. This forum is to help others with technical coding problems, not to spoonfeed others who cannot write code.
To start with HTML: [http://www.w3schools.com/html/].
A nice HTML book: [http://www.amazon.com/HTML-Dummies-Ed-Tittel/dp/076450214X].
To start with JSP/Servlet: [http://java.sun.com/javaee/5/docs/tutorial/doc/ (part II chapters 1-8)].
A nice JSP/Servlet book: [http://www.amazon.com/Head-First-Servlets-JSP-Certified/dp/0596516681].
It boils down to having a HTML <form>, <input type="text"> and <input type="submit"> in the JSP page and havinig a Servlet with necessary code in the doPost() method which obtains the request parameter, queries the database, stores the result in the request scope and forwards the request to a JSP for display -which on its turn uses JSTL c:forEach to iterate over the list of results.
Good luck. If you ever have a technical JSP/JSTL question/problem, you're welcome to ask here.

Hierarchical data structures (in a single table)

Hi,
If I have a hierarchy of objects stored in a table -
ORG_UNIT
ID
PARENT_ID
NAME
And the JDO mapping for an OrgUnit contains a parent OrgUnit and a
Collection of children.
Is there an efficient way of pulling them out of the database.
It is currently loading each individual parent's kids.
This is going to be pretty slow if there are say 500 OrgUnits in the
database.
If it would be better to pull them all out and build the hierarchy up in
code (as it was being done in straight JDBC). How can I efficiently obtain
the parent or children without doing exactly the same?
Thanks,
Simon

Simon,
There will be no db access for every child - you will read all child records
for a particular parent at once when you try to access its child collection.
Granted that for terminal leaves you will get an db access to load an empty
collection so effectively you will get a db access per node. If your goal is
always to load and traverse entire tree it will be expensive. But the
beauty of hierarchical structures is that while they could be huge millions
of nodes you do not need to load it all to navigate - just the path you
need. This is where lazy loading excels so overall on large trees you will
be much better of not loading whole thing at once. However if you still want
to do it nothing prevents you from not having persistent collection of child
records in OrgUnit class at all but only a reference to a parent, load
entire table using query and then build tree in memory yourself as you
iterate over the query resultset. You can probably even do it in a single
iteration over the resultset. I would never do it myself though . In my
opinion it defeats ease of use and cleanness of your object model.

AdvancedDataGrid - create Array (cfquery) with children for hierarchical data set

I'm trying to create an AdvancedDataGrid with a hierarchical
data set as shown below. The problem that I am having is how to
call the data from a ColdFusion remote call and not an
ArrayCollection inside of the Flex app (as below). I'm guessing
that the problem is with the CFC that I've created which builds an
array with children. I assume that the structure of the children is
the issue. Any thoughts?
Flex App without Remoting:

I had similar problems attempting to create an Array of
Arrays in a CFC, so I created two differents scripts - one in CF
and one in Flex - to build Hierarchical Data from a query result.
The script in CF builds an Hierarchical XML document which is then
easily accepted as HIerarchical Data in Flex. The script in Flex
loops over the query Object that is returned as an Array
Collection. It took me so long to create the XML script, and I now
regret it, since it is not easy to maintain and keep dynamic.
However, it only took me a short while to build this ActionScript
logic, which I quite like now (though it is not [
yet ] dynamic, and currently only handles two levels of
Hierarchy):
(this is the main part of my WebService result handler)....
// Create a new Array Collection to store the Hierarchical
Data from the WebService Result
var categories:ArrayCollection = new ArrayCollection();
// Create an Object variable to store the parent-level
objects
var category:Object;
// Create an Object variable to store the child-level
objects
var subCategory:Object;
// Loop through each Object in the WebService Result
for each (var object:Object in results)
// Create a new Array Collection as a copy of the Array
Collection of Hierarchical Data
var thisCategory:ArrayCollection = new
ArrayCollection(categories.toArray());
// Create a new instance of the Filter Function Class
var filterFunction:FilterFunction = new FilterFunction();
// Create Filter on the Array Collection to return only
those records with the specified Category Name
thisCategory.filterFunction =
filterFunction.NameValueFilter("NAMETXT", object["CATNAMETXT"]);
// Refresh the Array Collection to apply the Filter
thisCategory.refresh();
// If the Array Collection has records, the Category Name
exists, so use the one Object in the Collection to add Children to
if (thisCategory.length)
category = thisCategory.getItemAt(0);
// If the Array Collection has no records, the Category Name
does not exist, so create a new Object
else
// Create a new parent-level Object
category = new Object();
// Create and set the Name property of the parent-level
Object
category["NAMETXT"] = object["CATNAMETXT"];
// Create a Children property as a new Array
category["children"] = new Array();
// Add the parent-level Object to the Array Collection
categories.addItem(category);
// Create a new child-level Object as a copy of the Object
in the WebService Result
subCategory = object;
// Create and set the Name property of the child-level
Object
subCategory["NAMETXT"] = object["SUBCATNAMETXT"];
// Add the child-level Object to the Array of Children on
the parent-level Object
category["children"].push(subCategory);
// Convert the Array Collection to a Hierarchical Data
Object and use it as the Data Provider for the Advanced Data Grid
advancedDataGrid.dataProvider = new

How to sort data in results table(advanced table) based on some conditons

I have a requirement like below I have 3 search columns and 3 sort columns in the page. when user enter values in the search columns I will get results into advanced table. After I got results into results table. User will enter values in sort columns and hit sort submit button, Now the final results data should first display the selected sort values first and remaining data in alphabetical order.
ex: select a,b,c form table1 where a = nvl(:1,a) and b = nvl(:2,b)
results from main query
a , b,c,d,e,f
now user selects a value a1 in column a then results from main query data should display the a1 records first and remaining all records in alphabetical order.
Please let me know how can we approach to solve this problem.
Thanks,
KC.

Hi
Use the following method :
Set the OrderByClause in your voImpl():
the following is the description of OrderByClause method :
setOrderByClause
public void setOrderByClause(java.lang.String expr)
Sets the ORDER BY clause of the View Object's query statement. Bind variables can be specified using '?' as a place-holder for the value. The new ORDER BY clause does not take effect until ViewObjectImpl.executeQuery() is called.

Alter a BAPI Result Table, how to get into the display "loop" ?

Hello all,
i have a problem regarding the result rows of a RFC/BAPI Call.
There are three views, let's say 1,2,3. In View 1, i call a BAPI, and display the results in a table in View 2. I added a button in each row, which calls View 3 and displays some details concerning the selected row.
I now want to store a flag for each row, that has been displayed in this way.
In View 3 i store the key value of the displayed row in an own value node in the context.
When i go back from View 3 to View 2, i want to see that flag (in an extra column) in every row, that has been selected in this session.
So i do not know, how to alter a single row in the BAPI result table, how to get into the "loop" that is used by WD to display the table.
already tried a supply function, but i was not able to alter single rows.
Any suggestions/tips or perhaps code fragments of working supply functions ?
Thank you !

Hello,
I'm not sure whether I understood your problem correctly, but I will try to give an answer.
The easiest way I see is to copy the RFC Results to a Component Controller Context structure with an additional Flag field. You can use WDCopyService for copying.
Then on the event of selecting you set your flag as appropriate for you (e.g. if you want to use an image as flag you set the Image path) on the current element of your table. Then display View 3.
On going back View 2 should show now the new flag values...
The trick is to copy the values (as at Time structures can not be expandend with new fields) and set the Flag on the onSelect event.
Hope this helps,
Frank

Result table data to be populated based on selection in the result list

Hi,
We have a parent data source "P" containing all the record types. Further we have two child data sources each having filters on exclusive record types(for ex. child1 containing record types X, Y, Z and child2 containing record types A, B).
In our page we have a result list associated with data source child1(record types X, Y, Z) and result table associated with data source child2(record types A, B). There exists common attributes among the attributes present in result list and in the result table.
Rest of the containers in the page namely search, breadcrumbs, guided navigation point to the parent data source("P") containing all the record types.
Whenever we select a value from the guided navigation using the common attributes both the result list and result table are getting filtered.
What we require is that, whenever an attribute(common attribute) is clicked in the result list, the data in the result table needs to get filtered based on the value of the attribute that is clicked.
Is this possible? If so, pl. suggest how.

Reg: Data getting repeated in the table and displayed in the Smartorm.

Hello Experts,
Requirement is to display header data from kna1table and item data from two tables faglflexa and bsid.
Layout is something like this.
Name and Address is capture from KNA1.
Item Details from faglflexa and BSID based on one condition, UMSKZ ne 'X' and 'Y' for the respective KUNNR from KNA1. First Item table.I have taken a separate internal table from print program
Item Details from BSID only based on one condition, UMSKZ eq 'X' and 'Y' for the respective KUNNR from KNA1. Second Item table. I have taken a separate internal table from print program
Calculation based on faglflexa and BSID table on one condition,UMSKZ ne 'X' and 'Y' for the respective KUNNR from KNA1. Third t Item table. Data from the first internal table
The complete thing should be displayed on Smartform for one Customer (kunnr). Then should go to the next customer.
I have a written a code like this, For Example.
loop at kna1 into w_kna1.
Used Table1 in smartform and give a loop to display the item details based on first internal table.
display itemdetails
Used Table2 in smartform and give a loop to display the item details based on second internal table.
display itemdetails.
Used Template to display the item details to display the item details based on first internal table.
endloop.
Now my problem is table 1 is coming fine. table 2 data is getting repeated for all the customers based on 1st customer data, how should i clear the workarea after every customer.
Similar pbm for the template which i'm using.
Please help me on this.
Thanks in advance.
Abdur Rafique

Hi Vishnu,
Thanks for replying. I cant use one single table to display the output. There are several conditions in two tables.
I have corrected the error of repetition data. Logic i will mention it below.
loop at kna1 into wa_kna1.
for header data " this is main table
loop at item_1 into wa_item_1. " for first item table
Data displayed.
loop at item_2 into wa_item_2. " for 2nd item table
Data displayed.
endloop. " for 2nd item table
data calculation based on first item table.
endloop. " this is for first item table
endloop." this is for 2nd item table.
The data which is there in the 2nd item table should display data based on the kna1 loop. Data is displaying properly but not in 1 table, say for example.
kunnr- 1000010
there are 9 items.
All the 9 items should be in 1 table. But here it is displaying 1 item in 1 table till 9 items in 9 tables.
I need to club all the 9 items in 1 table.
One more doubt is 2 items have same belnr (document number) i need to club this and add the wmbtr field and then display as 1 record.
So final records in 2nd item table should be 8 not 9.
Can you please help me on this.
Thanks in advance.

Problem in displaying update page when multiple results table regions.....

Hi,
In Search page, I have 4 Search result table regions.(1.PropertyResultsTable,2.HouseDetailResultsTable,3.WaterDetailsResultsTable,4.ElectricityResultsTable)
In PropertyResultsTable Search result table region when I click the update Icon its showing the Last table region's(i.e ElectricityResultsTable) update page.
Same thing happening for 2.HouseDetailResultsTable,3.WaterDetailsResultsTable also.
If my search page contain only one result table region I can able to update the record successfully.
How to get the correct update page if there is more than one results table and each table has the update icon to update the respective record.
Please suggest.
Thanks & Regards,
Sagarika

Hi,
Thanks for your response.
Each search result table has its own controller and I have one RootController for handling 'Go' button click.
Here is the code,
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
//Transaction
if (TransactionUnitHelper.isTransactionUnitInProgress(pageContext,
"waterDetailCreateTxn",
false)) {
am.invokeMethod("rollbackServiceInfo");
TransactionUnitHelper.endTransactionUnit(pageContext,
"waterDetailCreateTxn");
else if (TransactionUnitHelper.isTransactionUnitInProgress(pageContext,
"waterDetailUpdateTxn",
false)) {
am.invokeMethod("rollbackServiceInfo");
TransactionUnitHelper.endTransactionUnit(pageContext,
"waterDetailUpdateTxn");

public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
if ("update".equals(pageContext.getParameter(EVENT_PARAM))) {
// The user has clicked an "Update" icon so we want to navigate
// to the first step of the multistep "Update Employee" flow.
// Retain AM
// Do not display breadcrumbs

Could query form and result table display at seperate pages

we are new at html db, there are a few of questions we need to clear before we make decision to use HTML DB to develop our next version of application: (I seperate them at differenct topics).
* Could query form and query result table display at differenct pages?
Thanks
Lei

yeah, this is surely possible...and quite easy. you'd just set your form page up as you'd like. put a button on that page with a branch to your report page. then have your report query refer to the items you defined on the form page. so if your form page had an item called P1_JOB and P1_DEPTNO you could have your report use those items with a query like...
select ename, job, sal, empno, deptno
from emp
where :P1_JOB = job
and :P1_DEPTNO = deptno
...hope this helps,
