SDM Variable Substitution and Java WebDynpro

Hello,
Is it possible to read SDM substitution variable from a Java Webdynpro application ? If yes how can it be done ?
Best regards
Sebastien Garnier

My usual advice for someone going from scripting to Java is to forget everything you thought you knew and start fresh. There's just too much nasty going on in scripting that has no place in proper programming.

Displaying both ABAP webdynpro and Java Webdynpro tasks in the UWL

Hi,
We have two an issue when trying to get the UWL to process two different types of workflow tasks : ABAP webdynpro and Java webdynpro.
Examples of these tasks are:
TS12300097 u2013 LeaveRequestApprover u2013 Java Webdynpro
TS17900100 - ASR_PROCESS_EXECUTE u2013 ABAP webdynpro
We have two backend systems configured
SAP_ECC_Financials u2013 This has the WAS host pointing to the java stack (xxx:50000)
SAP_ECC_Workflow u2013 This has the WAS host pointing to the ABAP stack (xxx.80xx)
In transaction SWFVISU all the tasks which use Java webdynpro have been configured to use the u2018Javau2019system (SAP_ECC_Financials) using the SYSTEM_ALIAS parameter
In the UWL configuration the system SAP_ECC_Workflow has been registered
In addition to this all u2018Javau2019 tasks have had an extra UWl config XML created to ensure that the SYSTEM_ALIAS is set to SAP_ECC_Financials
The system SAP_ECC_Workflow has been re-registered
The UWL cache has been cleared
However when we try to launch the java webdynpro tasks the system is trying to access the ABAP stack (It is still trying to access the Web AS location for the system SAP_ECC_Workflow even though the system alias was specified as SAP_ECC_Financials )
The ABAP webdynpro tasks (in this case a HCM process and form) are launched correctly
If we try the reverse (i.e register the Java system SAP_ECC_Financials and change the SYSTEM_ALIAS parameter for the ABAP webdynpro tasks to system SAP_ECC_Workflow) then the reverse happens. The java tasks can be launched and the ABAP tasks cannot.
Does anyone have a solution to this problem. Surely other people have implemented both ABAP and Java webdynpro workflows?
Any help much appreciated
Andrew

Thanks a lot for all your replies..
The workitem type registration has been done already, but still it doesn't work..
But here is the actual problem...
There is a link 'Execute Workitem' in the inbox of the approver, or the second level manager...
In the leave application, when we click on this link it is taking to the portal as the task is the Webdynpro Java application task. Whereas, when using ABAP webdynpro application task, it is taking to R/3 - which means that the user cannot access this link without R/3 access. The users are given only portal access, they don't have access to backend R/3.
The requirement is that the link has to take the user to portal directly instead of R/3 - i.e it should ask only for the portal id and password.
Since it was working fine with leave application, I changed the task to Java webdynpro task, but I think the Java Webdynpro application is not deployed in the server.
Please can anybody suggest.

Sushmitha

Variable Substitution and Dynamic Configuration

Hi All,
In Variable Substitution , the name that should be given the the receiver payload should be part of the Source Payload unlike the Dynamic Configuration wherein the file name can be generated dynamically during mapping.
I have the following questions
1.Dont we need to write the UDF for the Variable substitution?
2.Cant we do the Dynamic configuration without writing UDF?If so then how?
3.In Dynamic Configuration the file name is generated dynamically.But where does the file name come from if it is not the part of the source payload?
Thanks in advance

Hi Shwetha,
1.Dont we need to write the UDF for the Variable substitution?
No. Here we are accessing the contents of the payload to the target. So no UDF required.
2.Cant we do the Dynamic configuration without writing UDF?If so then how?
Yes and No.
Because we can set only few Dynamic configuration values without UDF.
If both source and target are File, then check ASMA on both sender and receiver. Then u can get the source directory name and source file name for target also without any UDF.Also some other parameters.
3.In Dynamic Configuration the file name is generated dynamically.But where does the file name come from if it is not the part of the source payload?
The file name comes along with the source in the payload as a attribute in header. U can view this in SXMB_MONI, and Dynamic Configuration.
In Dynamic Configuration the file name is generated dynamically.
No the file name is taken as it is from the source, if u want to change dynamically that u have to do in a UDF.
I hope this will clear all doubts,

Filename generation with variable substitution.

Hi,
I am currently working on a senerio in which file is receiver.The requirement is to generate file at target with the file name as message id.How can i use VARIABLE SUBSTITUTION and acheive this.
(Add message id in configuration should not be done.)

Hello shruthi,
              Please try this for the filename creation,
1. Create a UDF in the message mapping named getFileName, select only one input (to pass the messageid) and paste this coding there;
/* getFileName User Defined Function
// function to create name of output file
String filename;
filename = strFile;
try {
// initialize DynamicConfiguration for create file with given name
DynamicConfiguration conf = (DynamicConfiguration) container
       .getTransformationParameters()
       .get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "FileName");
//create file with the specified name
conf.put(key, filename);
} catch (Exception ex) {
return filename;
2. In the target structure header field perform this mapping,
Messageid -> getfFileName UDF -> Target Structure Headerfield
3. Then in the Integration directory under the target tab
check the Use - adapter specific message attributes and File Name
Please follow the steps and let me know if u still face the same problem.

Communication channel - Variable Substitution error,.

Hi,
I am having the following mesage type used in messag emapping as a target structure
mt_data
-> Variable1
I am having a validation on mt_data node in message mapping for generating it, if condition is satisfied mt_data will be generetaed. Under mt_data i am having a variable. This variable is getting populated with some data using normal source to target mapping.
I am using this variable in my communication channel as a variable substitution, and is used to replace file name.
The issue I am facing is, when the mt_data fails to get generated (valid reason, since validation to generate it failed), communciation channel in RWB fails saying variable for substitution not found.
Kindly advice.
Thanks,
Mudita

The issue I am facing is, when the mt_data fails to get generated (valid reason, since validation to generate it failed), communciation channel in RWB fails saying variable for substitution not found.
1) make a check on the variable in receiver determination itself...so that if fails then the message stops in Receiver determination itself....why to take it forward till channel and then fail.
2) Make use of some constant term to fill the variable in the mapping if the validation fails.....this will help to put value in the variable even when the validation fails and the message does not fail in channel...filename created.
You need to check with the functional people on how they want the message prcessing to occur when the variable cannot be created by the mapping logic.

Abhishek.

FTPs connection error:When using Variable substitution for Directory path

Hi
I am transferring data from BI to xml file via PI: Here a Client proxy from BI sends the data to PI and the PI FTPs the XML file to a remote location. For FTP I am using FTPs SSL connection.
It was working fine untill I used Variable susbstitution to determine Directory path dynamically. I am using this because different xml files are intended to goto the different locations.
I did the variable substitution like this:
Target Message Structure:
---> Target Directory: %var1%
<?xml version="1.0" encoding="UTF-8" ?>
<MT_BI_EXTRACT_FILE>
<Header>
<Directory>/Customer</Directory>
</Header>
<Detail>
</Detail>
</MT_BI_EXTRACT_FILE>
And in the variable substitution I am doing it this way
payload:MT_BI_EXTRACT_FILE,1,Header,1,Directory,1
And the error I am getting is:
Attempt to process file failed with Error when getting an FTP connection from connection pool: com.sap.aii.af.service.util.concurrent.ResourcePoolException: Unable to create new pooled resource: iaik.security.ssl.SSLException: Peer sent alert: Alert Fatal: handshake failure

Does anybody have some Idea of this ??
Regards
Naina

Hi,
I guess the problem is not with Variable Substitution..
Error when getting an FTP connection from connection pool:
So its a connection problem..
Also check the option Disable Security check and try again...
Try to check again if the interface is executing properly without Variable substitution and let us know..

Variable substitution for csv file

Hi Guys,
I am using Multimapping to generate 2 target messages and finally creating these 2 messges as csv files. But i need to use variable substitution (because dynamic configuration doesnt work in multimapping) to create the target files and i need to omit this node from content. i know if it is fixed length file we can use variable substitution and finally we can cut the variable in content conversion by using below method
fixedLengthToodShortHandling cut
Note:- I am using PI7.1
thanks,
madhu

You must separate variable filename from the other fields in several nodes.
Please, analyze if you can change your scenario, with next stucture:
<ns0:MT_MadhuMulti xmlns:ns0="http://rr.unilever.com/bconepi13">
<Strutcture>
<Name>Syam</Name>
<***>FEMALE</***>
<ID>123</ID>
</Strutcture>
</Strutcture>
<Strutcture>
<Name>Syam1</Name>
<***>Male</***>
<ID>789</ID>
</Strutcture>
<nothing>
<Filename>EmpDetails</EmpDetails>
</nothing>
</ns0:MT_MadhuMulti>
And then in your CC:
Recordset strucutre --> Structure,nothing
Structure.fieldSeparator --> ;
nothing.fieldFixedLengths --> 0
nothing.fixedLengthTooShortHandling --> Cut
nothing.endSeparator --> '0'

Carme.

Variable substitution using attribute

hi,
i want to use an attribute of an elemnet in variable substitution.
i know how to use element in variable substitution and i know that i can use message header attributes
in variable substitution, but if i create an element with an attribute how do i use it
(or is there a simple way to map a value in message mapping to message header attributes)?
Thanks
Tomer

Hi
Attribute is not supported for variable substitution.
You can try setting values for the Dynamic configuration and use it

Retrieve the message put in message header using variable substitution

hi,
i am using dynamic configuration to put some information in the message header.is it possible to retrieve the message using variable substitution and if it is possible then how it be done using variable substitution.
regards,
Meenakshi

Variable Substitution does not allow you to read all the messaeg header elements only some of them can be read/ access....for more info on how to read the message header elements refer: /people/jin.shin/blog/2007/04/27/sap-netweaver-xi-variable-substitution-with-adapter-specific-message-attributes-via-dynamicconfigurationbean
From the above blog:
When using Variable Substitution, only certain standard message header attributes can be used/accessed (e.g. sender_party,
sender_service, receiver_party, receiver_service, interface_name, interface_namespace, message_id)
Better use Dynamic Configuration to read the parameters.
I am wondering why you need to read the message header parameters when you are putting them using Dynamic Configuration.....cant you just get the details from the dynamic configuration UDF itself?
Regards,
Abhishek.

White lines generated in a txt File when using variable substitution

Hello,
I have a problem with a File generated by XI, my File Adapter is using variable substitution with reference to a field of my message type. I use content conversion as well and the generated file has a white line in top of file.
How could I avoid this and make the white lines disappear? I was trying a lot of things but I dont really know how to solve this issue, the following is the data type used:
<FILE_NAME></FILE_NAME>
<COMPANY>
     <COMPANY_CODE></COMPANY_CODE>
     <COMPANY_NAME></COMPANY_NAME>
     <ADRESS></ADRESS>
</COMPANY>
FILE_NAME is the field I use for variable substitution and COMPANY is declare as 0..unbounded.
Thanks a lot in advanced,
Luis

Hi Jai,
I have declare the following Content Conversion parameters:
Recordset Structure: COMPANY
FILE_NAME.fieldFixedLengths     0
FILE_NAME.fixedLengthTooShortHandling     cut
COMPANY.fieldFixedLengths     10,80,10,2,50,30,5,5,2,50,50
COMPANY.addHeaderLine     0
COMPANY.endSeparator     'nl'
But it does not work, I have the same white line in the beginning of the file. Do you have any other suggestion??
I couldnt find the blog written by Sravya either, could you post the link?
Thanks a lot,
Luis

Abap WebDynpro or Java WebDynpro

Hi All!
Which differenced are existing between Abap WebDynpro
and Java WebDynpro. Is it e.g. possible whether
one IView which has been created through Abap
technology combinable or adaptable with an Ivew which has been
created through Java Technology? Or is it a decision in principle
(policy decision)at the bgeinning of a project which one you take ?

Hi sas,
Read this article:

ABAP Vs JAVA WebDynpro

Hi friends,
I have 6yrs of experience in SAP ABAP/4. I am new to WebDynpro. I have a pretty small question.
Among ABAP WebDynpro and JAVA WebDynpro, which one will have more demand in future wrt market requirement.
Thanks in advance for the information.
Rgds,
AK

Hi AK,
I have worked on both and following is the difference:
Web Dynpro for ABAP:
Web Dynpro for ABAP or Web Dynpro for ABAP (WD4A, WDA) is the SAP standard UI technology for developing Web applications in the ABAP environment. It consists of a runtime environment and a graphical development environment with special Web Dynpro tools that are integrated in the ABAP Workbench (SE80).
The use of declarative and graphical tools significantly reduces the implementation effort
1) Web Dynpro supports a structured design process
2) Strict separation between layout and business data
3) Reuse and better maintainability by using components
4) Automatic operation of the Web Dynpro application using the keyboard
5) User interface accessibility is supported
6) Full integration in the reliable ABAP development environment
for more see this:
http://help.sap.com/saphelp_nw2004s/helpdata/en/77/3545415ea6f523e10000000a155106/frameset.htm
Web Dynpro for Java:
Web Dynpro is a client-independent programming model of the SAP NetWeaver technology platform for developing user interfaces for professional business applications. It is based on the model view controller paradim which ensures that the business logic is separated from the presentation logic. This architecture is visible in the Web Dynpro perspective of the SAP NetWeaver Developer Studio (NWDS).
Web Dynpro helps you with the development of Web applications by:
1) Ensuring platform-independence with the meta model approach
2) Minimizing the implementation effort through declarative programming
3) Supporting a structured design process by applying the model view controller paradigm
4) Providing reuse and better maintainability by using components
5) Providing graphical support with tools in the Web Dynpro perspective
6) Providing the SAP NetWeaver Java Development Infrastructure (NWDI) which supports team work with different services such as source code versioning and the Central Build Service.
for more see:
http://help.sap.com/saphelp_nw2004s/helpdata/en/15/0d4f21c17c8044af4868130e9fea07/content.htm
The concept of Web Dynpro ABAP is identical with Web Dynpro Java and offers more or less the same functions
Hopw this will help you.
Cheers,
Darshna.

elton

reference: payload:Header,1,File_Name,5
File_Name is the 5 th field name
it should not be treated as position of the field in your XML....it is the number of occrence...as per your setting the file name should be taked from 5th occurence of File_Name....however this wont be the case....you need it from the only occurence present
So it should be Header,1,File_Name,1
below details are selected
adapter specific message attribute
file name
You dont need to set the above as you are using Variable Substitution and not ASMA....these are two different things
Why not implement Dynamic Configuration? Dont you have mapping in your scenario?
