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

Comm Channel Variable Substitution - Use of wildcards to reference payload

Hi!
I am building a solution to write out tagged / XML IDOCs to a file adapter. I am using variable substitution to build the file name to include the message type, sending partner etc... in the target directory and filename.
Is there a way to wildcard nodes in the variable substitution? For example:
<i>Currently</i>
payload:WMMBID01,1,IDOC,1,EDI_DC40,1,RCVPRN,1
<i>Desired</i>
payload:*,1,IDOC,1,EDI_DC40,1,RCVPRN,1
where * is any wildcard.
Reason is that we have multiple IDOC types and I want to avoid having to create multiple communication channels.
Help appreciate and rewarded. Many thanks, Duncan.

Hi Duncan !
You can create the desired target filename and target directory by using dynamic configuration via java UDF in mapping. This allows you to create a target filename and/or directory based on a string..then you could use only one comm channel.
to access info:
// access dynamic configuration
      DynamicConfiguration conf = (DynamicConfiguration) param.get(
          StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey KEY_FILENAME = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","<b>FileName</b>");
      // read value
      String Filename = conf.get(KEY_FILENAME);
// to write value:
conf.put(KEY_FILENAME, "MyNewFileName");

Receiver File Adapter:Variable substitution :FATAL ERROR

HI all
as per the previous thread :
<b>Receiver File Name Variable Substitution :payload: Fatal Error
in our idoc to file sceanrio, we are using simple <b>graphical mapping.</b>
for dynamic file name , variable field is at <b>Target message type</b>,So on using <b>Variable substitution</b>, again the error is same :

Ashutosh,
There is nothing to do with your mapping programs. Its the mistake in ur reciever file adapter configuration for variable substitution.I asked u whether u changed message mapping in order to implement the UDF!!
Did u tried checking the audit log. Ok just to see where u are going wrong, instead of using Payload :... in Variable substitution use Message:..... and give some interface name so that to check whether the file is created with Interface name.
Juz give a try!!!
Best regards

How to use attributes in variable substitution???:(

Hi all,
Could you please help me out in how to use attributes in variable substitution....
Regards,
Sundar

Hi,
Use Adapter Specific Identifiers , instead of Variable Name substitution.
Sender File adapter --> Adapter Specific Attributes --> Select File Name
Reciver File Adapter -->Adapter Specific Attributes --> Select File Name
In the mapping , use this code in an UDF to change the filename to what you want,
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String filename="YOURFILENAME";
String rSourceFileName = conf.put(key,filename);

Variable Substitution - How do I use a segment atribute ?

Hi all, I'm facing a problem with variable substitution in receiver comunication channel.
I got the follow message:
<?xml version="1.0" encoding="UTF-8"?>
<lote nro="000262007">
<etc>...</etc>
</lote>
I want to get atribute <b>nro</b> from segment lote to use in variable substitution, how can I do it?

Variable sucstitution doesnt allow a way to achieve this.
There could be some workarounds
1. Use some dummy element in ur xml message with same value as tht of the attribute.
2. Use adapter specific message attributes or dynamic file name functionality

Variable Substitution with tag attribute

Hi,
is possible to use variable substitution with tag attribute? as follow:
<root directory="xxx" filename="yyy">
<....
</root>
using variable substitution for directory : root,1,directory,1
root,1,filename,1

Hi,
I solved my problem using Dynamic Configuration to set the FileName and Directory fields in Adapter Specific Configuration. To use Variable Substitution only accept element in XML.
Thanks for all.

Variable substitution error while using Seeburger module parameter

Hi Freinds,
I would like to use the variable substitution in a receiver file adapter to add the invoice no.
(which is contained in the XML file) to the target filename.
In addition I have to convert the XML file to an X12 EDI format using the seeburger module "localejbs/CallBicXIRaBean".
As soon as this entry is made in the modules the following error message occurs:
"com.sap.aii.adapter.file.configuration.DynamicConfigurationException:
Error during variable substitution: com.sap.aii.adapter.file.varsubst.VariableDataSourceException:
Caught SAXException while parsing XML payload: Fatal Error: com.sap.engine.lib.xml.parser.ParserException:
XMLParser: No data allowed here: (hex) 53, 4f, 48(:main:, row:1, col:3)"
My problem is that the conversion from XML to X12 EDI is done before the variable substitution is started.
That`s why the reference for the variable is no longer valid as the file is already converted to a X12 EDI (=flatfile) format.
If I disable one of the two steps (either 1:1-mapping or variable substitution) the other step runs properly.
Has anybody an idea how to solve this topic?
Is it possible to specify the variable substitution as module?
If this is possible I could solve it by just reordering the two steps in the module chain.
Regards
Venkatesh

Use Dynamic Configuration Bean to set this value. You have to use this well before "localejbs/CallBicXIRaBean".
Check SAP note : 974481 for more information.

Second Approach if the above approach doesnt work.
Use Dynamic Configuration concept in UDF to set the filename under message Mapping.

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?

Abhishek.

File-Adapter: Variable substitution form payload XML-attribute

Hi experts,
is possible to use XML-attribute-content for variable substitution in file-Adapter?
extract from XML:
<?xml version="1.0" encoding="utf-8" ?>
- <all>
- <transaction <b>file="filename"</b>>
- <table name="BPAADDRESS" options="insertIfUpdateFails">
- <record id="1">
<hkeycol name="BPAMAINHKEY">0010500345</hkeycol>
<hkeycol name="USAGE">Invoice</hkeycol>
</transaction>
I want to get the value "filename" = attribute file of transaction.
Is this possible?
Thanks a lot,
Florian

I have done this taking a field from the XML.
You have to map the location of the field within the XML...
Taken from:
http://help.sap.com/saphelp_nw04/helpdata/en/bc/bb79d6061007419a081e58cbeaaf28/frameset.htm
Variable Substitution (Target Directory/File Name Scheme)
If you set the Enable indicator, you can enter variables for the Target Directory and File Name Scheme. Enter the names of the variables and references in the table.
●      Enter each variable that you reference in the Target Directory and File Name Scheme fields without the surrounding percentage sign under Name of Variables in the table.
The variables can refer to attributes of the message header or elements of the message payload.
○       If the variables are to refer to an attribute of the message header, add the prefix message: to the name of the variable under Reference. You can specify the following attributes of the message header:
sender_party, sender_service, receiver_party, receiver_service, interface_name, interface_namespace,
message_id (message ID with hyphens, for example 9fbe1ff1-9a0d-11d9-8665-cbf10a126331)
message_id_hex (message ID in hexadecimal format, for example 9fbe1ff19a0d11d98665cbf10a126331)
For example, if you want to specify the interface name from the message header in the target directory or in the file name scheme, enter message:interface_name as the reference.
If one of the message attributes contains characters that are not permitted in a file name, for example \, /, :, *, ?, ", <, >, |, then these characters are replaced by an underscore ("_").
○       If the variable refers to an element in XML schema, add the prefix payload: to the information under Reference. The reference then comprises a pseudo path description in the form of a comma-separated list with the schema namea,na,nameb,nb,....
namea,nameb,... corresponds to the element name and na,nb,... corresponds to the occurrence of the element name at the respective level in the document.
The description begins at the root of the document and ends at the respective element.
To reference the element that is in bold in the example, the following expression is used: payload:root,1,e1,1,e2,2
The parser searches for the first occurrence of the root element at the first level. It then searches for the first occurrence of e1 at the second level and for the second occurrence of e2 at the third level. The content of the last element (Example Value) is set as the value for a specified variable.
<?xml version="1.0" encoding="UTF-8" ?>
<root>
<dummy>
     <e1>
        <e2>Data_1</e2>
        <f/>
        <g attr="abc">text</g>
        <e2>Data_2</e2>
     </e1>
</dummy>
<e1>
     <e2>illegal/value</e2>
     <f/>
     <g attr="abc">text</g>
     <e2 attr="fghij">Example Value</e2>
</e1>
</root>
●      To disable the check the adapter performs for the element data, set the Disable Security Checks indicator.
Otherwise, the adapter checks whether the element data contains characters that could lead to security risks in the file system environment. The check includes the characters /, \, and ...

Using attributes from AdapterSpecificMessage in 'Variable Substution"

Hi all,
Is there any possibility of acceding to an atribute determined dynamically during mapping from Variable Substitution in a receiver FTP communication channel?
This is the scenario:
Inside mapping, we are determining a folder and storing it under header variable 'directory'. If I use 'Adapter Specific Message Attributes" directory, it works ok and writes the file into the appropiate folder.
The thing is we need for development to store that file under the same structure but under another extra folder:
If in QA it's /out/file, in DEV it should be /DEV/out/file .
I was trying to do this this way:
target directory = /DEV/%var1%
Variable Substitution
var1 = message:directory
And obviously, it's not working. Do anybody know any way to access to that value from Variable Substitution?
Thanks in advance, Iñaki.

java.util.Map map = container.getTransformationParameters();
String MSGID = (String)map.get(StreamTransformationConstants.MESSAGE_ID);
return MSGID;
Could not make it out what exactly you are asking for.....if you want ot access the Message Header variables then using the above code you can do so....just write which value you wan to access..check this link to know the message header fields:

Error-Receiver File Adapter using Variable substitution when file is empty

XI Experts,
We are on PI 7.0, SP14.
We are using variable subtitution to get the filename from source message. This works fine as long as we have data in the payload for filename element. But we have a scenario where we don't have to create file when certain condition does not exists in source message so in the message payload filename element will not exists in such condition and file will be empty and we should not create file.
Parameter in the communication channel for Handling empty message is "Ignore".
Does anyone knows how to handle this scneario. We don't want to default any file name in the message mapping if source file name element does not exists.
We are following getting error in the Adapter engine.
MP: Exception caught with cause com.sap.aii.af.ra.ms.api.RecoverableException: Error during variable substitution: com.sap.aii.adapter.file.varsubst.VariableDataSourceException: The following variable was not found in the message payload: file: com.sap.aii.adapter.file.configuration.DynamicConfigurationException: Error during variable substitution: com.sap.aii.adapter.file.varsubst.VariableDataSourceException: The following variable was not found in the message payload: file
Thanks

You can implement this by writing the module to throw an exception or whatever method you want to execute.
If you don't want to receive an error message then module is suitable for you.

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..

Error while using the variable name "VARIABLE" in variable substitution

Hi Experts,
I am using variable substitution to have my output filename set as a payload field value. It is working fine when I am using the variable name as fname, subs etc but channel goes in error when I am using the variable name as "VARIABLE". This is probably a reserved word but i would like to know where i can find a detailed documentation on this. Say things to note / restrictions while using variable substitution.
This is the error in the channel:
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error during variable substitution: java.text.ParseException: Variable 'variable' not found in variable substitution table: com.sap.aii.adapter.file.configuration.DynamicConfigurationException: Error during variable substitution: java.text.ParseException: Variable 'variable' not found in variable substitution table
Thanks,
Diya

Hi Zevik,
Thanks for the reply. The output file is created correctly by merely changing the variable name to something else and hence the doubt.
Below is the configuration:
Variable Substituition
VARIABLE payload:interface_dummy,1,Recordset,1,Header,1,field1,1
Filename schema : TEST_%VARIABLE%.txt
Output xml structure:
<?xml version="1.0" encoding="utf-8" ?>
- <ns:interface_dummy xmlns:ns="http://training.eu.unilever.com">
- <ns:Recordset xmlns:ns="http://training.eu.unilever.com">
- <Header>
<identifier>HDR</identifier>
<field1>001</field1>
<field2>001</field2>
<field3>R</field3>
</Header>
- <Detail>
<identifier>A</identifier>
<field1>000000002</field1>
<field2 />
<field3>Doretha.Walker</field3>
</Detail>
I thimk my configuration is correct as it is working correctly with the variable name change, However, maybe i missed something !

Used variable substitution to substiture the field 'date' in file name

Hi gurus
I have used variable substitution to substiture the field 'date' (dd/MM/yyyy/hh/mm/ss) in the file name so when empty payload (a valid xml ) is generated by Message mapping then the communication channel is failing by showing the following error
File processing failed with com.sap.aii.adapter.file.configuration.DynamicConfigurationException: Error during
variable substitution: com.sap.aii.adapter.file.varsubst.VariableDataSourceException: The following variable was not found in the message payload
: date
As of now the business is not getting effected as the business scenarion needs only customer master data at the reciever side But when ever there is no custmer master data in the sourse side the message mapping is generating an empty payload and the communication channel is failing ( so it is an internal issue and is there any way which could solve the both (ie the business must not get effected and as well the communication channel must not fail)
any coments on this will be higly apreciated
thanks and regards
sandeep

Hi Sandeep -
Yes If you use the Variable substitution from the payload , that perticular field has to be generated in the target structure.
To handle this You can do the following:
Sourcefield --->exists -> IfThenElse-->TargetField
Where     SourceField>exists(node function)-> If
               SourceField -
>Then
               CurrentDate(Date Function)----->Else
Hope this will help !!
Regards.
Jeet.
