Conditional Select - How to retrieve data based on different cond.

Hi
I have a requirement to retrieve Equipments for Sales orders. But the selection criteria includes that if an Equipment with a EQTYp = 0 exists, only that record needs to be retrieved. And if no such equipment (Eqtyp = 0) exists, then retrieve any equipment from the Sales Order.
I have for this reason selected a process as follows:
First collect all sales orders, collect Equipments for them from SER02 and OBJK. And then look for a EQtyp = 0 equipment for each sales order line item. If no such one is found, then one of the other equipments is selected.
As the report needs to be run open (without specifying any sales orders) at times, the amount of sales orders that are to be checked becomes huge and so retrieving the equipmets also becomes hectic in my current process.
So, is there any other way to retrieve this information? or can a select be formulated in such a way that it can decide to pick a EQTYP <> 0 equipment when a EQTYP = 0 equipment is not found.
Thanks in advance.

Hi
Is Equipment is an selection-screen field?
If so give Equipment value = o and # in the selection-screen while executing?
If that is not an selection-screen field in the select query in the where condition you can mention Equipment = 0 or
equipment # 0.
This can optimize the code some what.

How to retrieve data using logical database and custom select options

Hi all,
I have a selection screen which is displayed by logical database PSJ and I have two select options of my own. I need to retrieve data based on both selection screen of logical database and my own select options. How can I do it?
Thanks in advance.

Hai Gupta
Check the following Document & Links
1. A logical database is in fact
a program only.
2. This LDB provides two main things :
a) a pre-defined selection screen
which handles all user inputs and validations
b) pre defined set of data
based upon the user selection.
3. So we dont have to worry about from
which tables to fetch data.
4. Moreover, this LDB Program,
handles all user-authorisations
and is efficient in all respects.
5. tcode is SLDB
good info about Logical Database. you can check the link.

Re: How to Create and Use ldb in reports?
Re: Logical databases
http://help.sap.com/saphelp_46c/helpdata/en/9f/db9bed35c111d1829f0000e829fbfe/frameset.htm
Functions for displaying and changing logical databases:
Call Transaction SE36 or
Choose ABAP Workbench -> Development -> Programming environ. -> Logical databases
Interaction between database program and report:
During program processing, subroutines are performed in the database program and events are executed in the report.
To read data from a database tables we use logical database.
A logical database provides read-only access to a group of related tables to an ABAP/4 program.
advantages:-
The programmer need not worry about the primary key for each table.Because Logical database knows how the different tables relate to each other,and can issue the SELECT command with proper where clause to retrieve the data.
i)An easy-to-use standard user interface.
ii)check functions which check that user input is complete,correct,and plausible.
iii)meaningful data selection.
iv)central authorization checks for database accesses.
v)good read access performance while retaining the hierarchical data view determined by the application logic.
disadvantages:-
i)If you donot specify a logical database in the program attributes,the GET events never occur.
ii)There is no ENDGET command,so the code block associated with an event ends with the next event
statement (such as another GET or an END-OF-SELECTION).
1. transaction code SLDB.
2.enter name z<ldb-name>
3.create
4.short text
5.create
6. name of root node (here Ekko)
7. enter short text (f6)
8.node type -> data base table.
9.create
10 change logical DB
riht click on ekko and insert node
here node name ekpo
11.create
12. click on selections
13. press no Should the changed structure of Z<ldb name> be saved first.
14.select tables which you want to join.
15.transfer
16 now you have to o to coding part.
17. save
activate.
19.click to src code
double click on first include and activate

How to retrieve data from the HTML form in the JEditorPane?

I could quite easily use JEditorPane to render and display a simple HTML file.
My HTML looks like this:
<html>
<head>
<title> simple form</title>
</head>
<body bgcolor="cccccc">
<center><h1>SURVEY THING</h1>
</center>
<form id="survey">
<p>1.Type something in.</p>
<textarea cols=25 rows=8>
</textarea>
<BR>
<p>2.Pick ONLY one.</p>
<input type="radio" name="thing" value="0" Checked> NO choice <BR>
<input type="radio" name="thing" value="1"> First choice <BR>
<input type="radio" name="thing" value="2"> Second choice
<BR>
<p>3.Pick all you like.</p>
<input type="checkbox" name="stuff" value="A"> A <BR>
<input type="checkbox" name="stuff" value="B"> B <BR>
<input type="checkbox" name="stuff" value="C"> C <BR>
<input type="submit" value="give data">
<input type="reset" value="do clensing">
</form>
</body>
</html>
It gets diplayed fine and I can type in text, select radio buttons (they behave mutualy-exclusive,
as they should) and check checkboxes.
The problem I have is with retrieving the values which were entered into the form.
If I, after editing, try to write the html to the file using HTMLWriter,
it records the changes I made into the textarea, however all the radio and checkbox selections are lost.
Maybe the problem is that when I enter the values I do not use any methods like
insertBeforeStart and so on, but I believe I shouldn't need to use them to populate a form.
Especially I never change the structure of the HTML.
Also, when I try to traverse the Element tree and see the input elements attributes,
I can never see a change in the entered values. However it is probably b/c I am traversing through
the model and the changes are in the view (just a guess.)
Anyway, if anybody could direct me onto the right path: how to retrieve the values typed in the form,
or if it is possible at all in the JEditorPane, I would greatly appreciate.
thanks
maciej
PS. I have seen the answer to a similar question posted some time last year. However, I am trying
to find a soultion which allows forms/surveys to be built by people who have no java and only basic
html knwledge. And Axualize way is probably a little bit too "high-tech."

How to retrieve data from a web service

Hi
i am at very beginner level about web services.
I am searching for a simple example of retrieving data from a web services, but cant find.
How can i get xml data from a web service. i dont need to develop the web service it is already ready, i just need how could i fetch data from it.
Can somebody point out or give an example?
Thanks in advance

Hi,
just create a skeleton for the Web Service. In JDeveloper, create a new project and then use the "NEW" context menu option.
Navigate to "Business Tier" --> Web Services and select "Web Service Proxy"
In teh following, provide the WSDL reference to create the Java proxy. This gives you accss to the WS without having to parse the XML yourself

Pricing Conditions and how the pricing date is determined

Hi all,
Small question, i ahve some pricing conditions that use the Serives Rendered date and others that use the Pricing Date from an order, how is the condition decided on what date it uses?
Hope i have expplained this ok, if not and you need more info let me know.
Regards
Steve

Hi
There is a difference between Service Rendered Data and Pricing Date.
Normally Freight Conditions are maintained on Service Rendered Date so the freight will be picked on the basis of date on which the Actual Delivery done, whereas Pricing date is used for other conditions so that price will be based on the date on which the document created and the Pricing Date maintained in that.
In the same way there is a Billing Date which came in Invoice so price will be based on the date of Invoicing.
If you maintain the record in VK11 and test a cycle you will be able to find the difference easily.

Amitesh
