What is an element,when we call a function write_from?

what is an element,when we cal a function write_from what to assign for ELEMENT and WINDOW...?
Edited by: Alvaro Tejada Galindo on Feb 20, 2008 4:37 PM

Hi shekar,
The main reason of specifying the Function module Write_Form is to make the values visible in the particular window of the form.
For Ref, see the Below Function Module:
CALL FUNCTION 'WRITE_FORM'
EXPORTING
    ELEMENT = 'HEADER'
    WINDOW = 'MAIN'
EXCEPTIONS
    ELEMENT = 1.
In the above example, I need to declare a element in the Main window. So I have passed 'MAIN' in window and 'HEADER' in element.
REASON OF SPECIFYING:
Suppose you want to display the values the internal table say suppose it_itab. If you specify this in the sap script like &it_itab-f1& or &wa_itab-f1& without using write_form wont work.
So this will be specified as,
SE38:
Loop at it_itab into wa_itab.
CALL FUNCTION 'WRITE_FORM'
EXPORTING
    ELEMENT = 'HEADER'
    WINDOW = 'MAIN'
EXCEPTIONS
    ELEMENT = 1.
endloop.
Inside Script:
Inside the Main window:
/E     HEADER
      &wa_itab-f1&
what happens is after the loop statement as soon as it encounters the write_form, it searches for the element 'HEADER' in the Main window and values become visible in the form.
If u need any more details, please tell.

Layout - not recognize the element when i call the function write_form

Hi experts,
I got a layout(se71) that not recognize the element that i add in the MAIN window when i call the layout from a program.
what could it be?
i add the element in se71.
any help will be appreciated.
Michal.

Hi!
the write form that u are calling should be as below....
CALL FUNCTION 'WRITE_FORM'
   EXPORTING
      element                  = 'ELEMENT'
      window                   = 'MAIN'
    EXCEPTIONS
      element                  = 1
      function                 = 2
      type                     = 3
      unopened                 = 4
      unstarted                = 5
      window                   = 6
      bad_pageformat_for_print = 7
     spool_error              = 8
      codepage                 = 9
      OTHERS                   = 10.
IF sy-subrc <> 0.
    MESSAGE 'MAIN window not called properly'(006) TYPE 'E'.
ENDIF.                               " IF SY-SUBRC NE 0
in the layout see if the code there with data element is proper as...
/E ELEMENT
   &var&
Also this write_form FUNCTION MODULE should be called b/w OPEN_FORM and CLOSE_FORM Function Modules.

How to pass a xml CDATA in string element when OSB calling a webservice?

How to pass a xml CDATA in string element when OSB calling a webservice?
I have a business service (biz) that route to operation of a webservice.
A example of request to this webservice legacy:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:eg="example">
<soapenv:Header/>
<soapenv:Body>
<ex:execute>
<ex:arg><![CDATA[<searchCustomerByDocumentNumber>
<documentNumber>12345678909</documentNumber>
</searchCustomerByDocumentNumber>]]></ex:arg>
</ex:execute>
</soapenv:Body>
</soapenv:Envelope>
the type of ex:arg is a string.
How to pass this CDATA structure to webservice in OSB?

Steps to solve this problem:
1. Create a XML Schema. E.g.:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
     elementFormDefault="unqualified">
     <xs:complexType name="searchCustomerByDocumentNumber">
          <xs:sequence>
               <xs:element name="documentNumber" minOccurs="0">
                    <xs:annotation>
                         <xs:documentation>
                         </xs:documentation>
                    </xs:annotation>
                    <xs:simpleType>
                         <xs:restriction base="xs:string" />
                    </xs:simpleType>
               </xs:element>
     </xs:sequence>
     </xs:complexType>
     <xs:element name="searchCustomerByDocumentNumber" type="searchCustomerByDocumentNumber"></xs:element>
</xs:schema>
With this XSD, the XML can be generate:
<?xml version="1.0" encoding="UTF-8"?>
<searchCustomerByDocumentNumber xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="searchCustomerByDocumentNumber.xsd">
<documentNumber>documentNumber</documentNumber>
</searchCustomerByDocumentNumber>
2. Create a XQuery to create a searchCustomerByDocumentNumber ComplexType. E.g.:
(:: pragma bea:global-element-return element="searchCustomerByDocumentNumber" location="searchCustomerByDocumentNumber.xsd" ::)
declare namespace xf = "http://tempuri.org/NovoSia/CreateSearchCustomerByDocumentNumber/";
declare function xf:CreateSearchCustomerByDocumentNumber($documentNumber as xs:string)
as element(searchCustomerByDocumentNumber) {
<searchCustomerByDocumentNumber>
<documentNumber>{ $documentNumber }</documentNumber>
</searchCustomerByDocumentNumber>
declare variable $documentNumber as xs:string external;
xf:CreateSearchCustomerByDocumentNumber($documentNumber)
3. In your stage in pipeline proxy add a assign calling the XQuery created passing the document number of your payload.
Assign to a variable (e.g.: called searchCustomerByDocumentNumberRequest)
4. Create another XQuery Transformation (XQ) to create a request to the webservice legacy. E.g.:
<ex:arg>{fn-bea:serialize($searchCustomerByDocumentNumberRequest)}</ex:arg>
For more information about xquery serialize function:
41.2.6 fn-bea:serialize()
You can use the fn-bea:serialize() function if you need to represent an XML document as a string instead of as an XML element. For example, you may want to exchange an XML document through an EJB interface and the EJB method takes String as argument. The function has the following signature:
fn-bea:serialize($input as item()) as xs:string

Similiar to the answer How to pass a xml CDATA in string element when OSB calling a webservice?
Use the xquery function fn-bea:inlinedXML rather than fn-ben:serialize
Steps to solve this problem:
1. Create a XML Schema. E.g.:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"

</xs:complexType>
<xs:element name="searchCustomerByDocumentNumberResponse" type="searchCustomerByDocumentNumberResponse"></xs:element>
</xs:schema>
2. Create a XQuery to create a searchCustomerByDocumentNumber ComplexType. E.g.:
3. Create a XQuery Transformation (XQ) to get the CDATA response to the webservice legacy. E.g.:
declare namespace ns0 = "novosiaws";
declare function xf:getReponse($searchCustomerByDocumentNumberResponse as element(ns0:searchCustomerByDocumentNumberResponse))
as element(searchCustomerByDocumentNumberResponse) {
fn-bea:inlinedXML($searchCustomerByDocumentNumberResponse/ns0:arg)
For more information about xquery function:
fn-bea:inlinedXML
The fn-bea:inlinedXML() function parses textual XML and returns an instance of the XQuery 1.0 Data Model.
The function has the following signature:
fn-bea:inlinedXML($text as xs:string) as node()*
where $text is the textual XML to parse.
Examples:
fn-bea:inlinedXML(“<e>text</e>”) returns element “e”.
fn-bea:inlinedXML(“<?xml version=”1.0”><e>text</e>”) returns a document with root element “e”.

What does it mean when you call someone and it goes straight to the 3 beeps to mean cancelled

hi
what does it mean when you call someone and it goes straight to the 3 beeps to mean cancelled? this phone doesnt even ring, it just goes straight to the BEEP-BEEP-BEEP, its an iphone 4 and on IOS7 and it was ringing eailier on in the day when i spoke to this person. it wouldn't mean i have been blocked would it?
what does all this mean?
thanks
mrredrunner100

i got my friend to message this person to see if they had the same problem, and the message went through and i think he got a reply, and all of a sudden this has started to work again (calls only) but apparently none of my messages went through that i have sent since the block activated. and they still havent even though there working again, and "apparently" a message was sent to me at 9pm today and it has never arrived. so imessage and text still isnt working, before i go asking this person about this, is this a genuine block or is there a phone problem?

What is the exact syntax for calling remote function module.

Hi to all
1.....what is the exact syntax for calling remote function module.?
Thanks and regards,
k.swaminath reddy

hi
good
Lets do simple example where you will first create a RFC in one server (say A) and create normal program in othere server (say B). Finally you will call the RFC in A from B.
Do the following steps for creating RFC in server A.
1. log on to server A
2. go to se37
3. Edit -> function groups-> create function group and give the function group name (say ZGRP).
4. create a FM ( say Z_TEST_RFC) in se37 providing the function group which is created just now.
5. go to attribute tab -> choose remote-enabled module from processing type.
so that your FM will become RFC.
6. provide the import parameter in import tab.
we will provide only two import parameters.
- parameter name : P_NUM1, typing: TYPE, associated type : I & check the pass value (all the parameters of RFC must pass by value).
- parameter name : P_NUM2, typing: TYPE, associated type : I & check the pass value
7. provide the export parameter in export tab.
parameter name : P_SUM, typing: TYPE, associated type : I & check the pass value
8. write the given simple code in source code tab.
FUNCTION Z_TEST_RFC.
P_TOT = P_NUM1 + P_NUM2.
ENDFUNCTION.
Do the following steps for creating ABAP program which will call the RFC in server B.
1. se38 - > creat a program.
2. write the given simple code.
data tot type i.
call function 'Z_TEST_RFC' destination 'XXXXXX'
exporting
p_num1 = 10
p_num2 = 15
importing
p_tot = tot.
write tot.
please note that XXXXXX is RFC connection which is avialable in sm59 transaction in server A.
-go to sm59 - > abap connection (list of RFC connection configurations are avialable). choose server B connection and replace it of XXXXXX in the code.
finally you can execute the normal abap program that will call the RFC and display the result.
reward point if helpful.
thanks

What does it mean when you call someone and your phone suddenly saids "end call"?

I tried calling a friend but the call didn't go through and instead it said call ended on my phone with 2 beep tones, what does this mean?

The call simply did not go through. It happens with cell phones.

Failed to run parallel path when using call library function node in LV2009

I have a problem with two parallel paths not being run in parallel on LabView 2009.
See the image below.
This code initializes an external device, the upper part contains a call library function node to download my code into the device. When done, the function returns and the "Done" flag is set to True.
The lower part contains a call library function node to check the download status, reporting the percentage of downloaded code.
This updates a progress bar that is referenced by the calling VI module and this works fine in LV 7, 8 and 2011. The lower path of the VI updates the progress bar while the CLFN in the upper part is still downloading code to my device.
Somehow, in LV2009 this does not work when running this inside my application. When running just the calling VI (the window showing the progress bar) it works but not when that VI is called by my application.
Is there some limit on parallel threads that is different in 2009 than in other versions ?
Or is there some other problem in 2009 that might cause this problem ?
My labview version is 9.0f3 (32-bit).
Regards,
Rob

I've just installed the DETT tool and checked what the different versions of LabView do.
In LV2009 the application instance runs in a thread (5) but the modal dialog (the VI above) then drops to thread 0 and stays in thread 0.
In LV2011, stays in the same thread as the application instance and only a trigger event (this could be the progress bar reference?) is executed in thread 0.
So it seems there is a 'feature' in LV2009 where modal dialogs are by default not following the preferred execution system set in the VI properties ...
When I change this from "same as caller" into another thread (I used "other 1") then my progress bar works as expected.
I'm not a LabView thread expert (not even a novice ) so I'm just guessing that "other 1" as a thread is OK. This VI only runs during startup of the application to download the code to my device.
To answer Ben's question: "What thread does a modal VI run in?":
In LV2009, the modal VI runs in thread 0 (UI thread ?). When the preferred execution system is set to another thread, the modal dialog still starts in thread 0 but then switches over to the other thread.
In LV2011, the model VI runs in the caller's thread (preferred execution system set to "follow caller") from start.
Thanks,
Rob

LabVIEW PDA reports COREDLL.DLL error when using Call Library Function Node

I'm trying to build a LV PDA app that calls an external DLL file built using embedded visual C. When configuring the Call Library Function node I select the stub DLL, configure the I/O parameters and select OK. When the configuration dialog closes I get the following error:
LabVIEW: LabVIEW.exe - Unable to Locate Component
This application has failed to start because COREDLL.DLL was not found. Re-installing the application may fix this problem.
I do not get this error when using the configuration dialog in the example VIs.
Any suggestions as to the cause and/or the solution?
Thanks,
Ryan

Hello -
When you create a PDA VI that calls a DLL, you must include the .c or .lib file that corresponds to the DLL. Take a look at these documents:

How to handle xml CDATA string element when OSB calling a webservice

Hi
Right, I'm new to OSB so bear with me.
The following is a response from am operation in a webservice.
As you can see there is a CDATA string in "<m:return>" element. I want to transform the CDATA string to XML.
I have searched the forum and found a couple of similar queries and tried following the answers and this is what I'm getting.
Please advise as to where I have gone wrong and how I can correct it.

The CDATA string hasn't been transformed.
Please help. What I have I missed.

I have amended the earlier Assign action to use an XQ to extract the CDATA string into the schema
My Assign is:

I have also changed my Replace, this time I am using an XQ which will map the schema to the XSD WSDL "ReservationCancelResponse"operation.
XPath: .

What do recipients see when I call mobile from Sky...

Hi all,
I have just signed up to the US subscription (calling US landlines and mobiles from Skype) - however, how does the person I am calling know that it is me? What do they see on their mobile phone? My skype username? A strange long number?
Any thoughts on this would be appreciated!!
PS I "do not" have a Skype number that Skype sells for an extra charge..
Cheers

Hi,
A strange long number, afaik.
But, according to == the FAQ == you probably might set up the caller identification by using your mobile number.

I get "dynamic memory is corrupt" when I call HarmonicAnalyzer function

Hello,
I am using a PCI-6025E to acquire analog signals. I want to measure the THD of some of them, so I have copied the function "Total_Harmonic_Distortion" from the THD_Analyzer.prj example of NI.
Sometimes, my program crash when it tries to execute the HarmonicAnalyzer function.
My program is multi-threading, the acquisition and the THD measurement is made in the same thread.
Someone can help me to fix this problem?
Thanks

Dear SebastianN,
thanks for your suggestion. I have tried to call the "CVIDynamicMemoryInfo" before the HarmonicAnalyzer function, but it has no effect on the program itself (I get always the memory corrupt message).
Yesterday I tried to call the Total_Harmonic_Distortion only if the RMS value of my buffer is greater than 1.0, and I replaced all my malloc functions by calloc functions. Till now it seems to work, but I cannot understand why, and I'm not sure that really I fixed the problem...

Product drilldown reports - Not linked when selecting call up functionality

hi all,
i running the tgt/act/var cumulative report (s_alr_87013139) and values are showing as expected, but when i try to view the order involved in the material, by selecting the material number and click on the "call up report" functionality, system will be showing the "no records selected" message. Any idea why this is happening? Thanks
Regards
Mg

Hi,
You should check that there are only two summarisation levels for each Cotrolling area (for reports with material number and without) - please see the note 422543. For some (unknown) reasons sometimes there are more than two levels per controlling area in the system. The drill down report then tries to read from the wrong level and can't find any data.
If you have more than two in one controlling area you should delete them (within TA KKDV). If the results in the drill down report are not correct afterwards, you should delete all levels and run TA KKRV (data collection) again afterwards.
Regards,
Declan

What does it mean when it says transfer function normalized

I am running my VI which is control system model. I have changed transfer function into a cluster of Numerator and Denominator and through a cluster unbudle into transfer function subVI. It does not show any fault until I run it and then it shows message "Transfer function normalized" what could be the problem. I will try and attach the vi. The Vi is created in GSim Tool set

This error is because the order of your numerator is higher than the order of the denominator of your transfer function. This is an impossible physical situation and leads to a delta function and its derivatives in the output response. Physically realizable systems must have the order of the denominator in the transfer function greater than the order of the numerator.
