How to enable variable substitution?

Hi,
I'm looking for some note that guides you how to enable variable substitution to create Target Directory/File Name Scheme at runtime.
Do you have some helpful tip?
Best regards,
Gerardo.
PS. i'll post reward points.

hi,
if you upgreaded you need to do: (to see new adapter functinality)
3. I can't see my adapters in the adater monitoring after the import of a new SP
a) try reimporting "SAP Basis software component"
b) take a look at the XI installation guide on how to do it: "Importing the XI Content for Software Component Version SAP Basis 6.40"
from SAP XI FAQ
BTW
but don't use varible substitution ! 
use adapter specific messages - much easier, better

How do we enable Variable Substitution during Contract Generation

Hello experts,
I am working with the Contract Generation Variable Library and according to some of the Help documents, it is possible on the Contract Tokens to override the default values during Contract Generation.
I am not sure why, but on our system, this function doesnt seem to work.
So for eg, if my token "Valid From" picks up the value from the system, it becomes non-editable.
Effective Date | <%Agreement.EffectiveDate%> | 26-08-10
I would like to override the value 26-08-10 before the Document is generated.
Please let me know if anyone has faced this problem before and found a solution.
Thanks & Regards,
Reshma

I kept searching through MSDN and found a page that describes SqlPackage.exe (http://msdn.microsoft.com/en-us/library/hh550080(v=vs.103).aspx). This page says that SQLCMD variables
can be specified on the command line.
"SqlPackage.exe initiates the
actions specified using the parameters, properties, and SQLCMD variables specified on the command line."
The page does not describe the syntax for specifying SQLCMD variables nor whether values specified on the command line overwrite any values in the .dacpac file. Can somebody confirm that specifying SQLCMD variable values on the command line will overwrite
any values included in the .dacpac at build-time?

How to enable variable highlighter on Vista (JDeveloper 10.1.3.3)

I have been working with JDeveloper for a while I have tried the 10.1.3.3 & the new preview 2 on my Windows Vista laptop, but I can't get the open source update Varible highlighter and code colorizer to work.
I have tried everything with the 10.1.3.3, but nothing is working, so I wondered if it's a Vista issue? If anybody know any solution for my problem I would be greatful because I really want that to work in my program. I tried installing the new preview version, but it didnt seem any better. That's why I am writing and if you got any good advices for a user using JDeveloper on Vista I would be greatful.

User,
I have the variable highlighter extension installed (10.1.3.3), and it's working just fine. What JDK are you using with JDeveloper (the one that comes with the windows download, or another one)? I am using 1.5.0_11. Just on the off-chance, do you have JDeveloper installed in a directory with spaces in the name? JDev sometimes has a problem when you do this.
A quick search on the forum finds a few other posts. [url http://forums.oracle.com/forums/thread.jspa?messageID=1886267]This one has some of my experiences.
Hope this helps.

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 nro 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

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);

How can i use substitution variable

Hai All
This is my sql statement
SELECT (TO_DATE(TO_CHAR(Intime,'DD-MON-YYYY')||' '||
TO_CHAR(0815,'0000'),'DD-MON-YYYY HH24:MI')-intime) * 24*60
from dail_att where to_char(intime,'hh24mi') between 0700 and 0815 ;
Here my table name called Dailyattendance
Intime field is declared as Date Type
So now i have hardcoded 0815 and now my intime is subtracted from this time so i can calculate the employee
coming late so how can i use substitution variable here to give the value at run time
Ie i need to give 0815 instead or any other time at runtime
Thanks In advance
Srikkanth.M

Where exactly are you planing to use it? Is sqlplus or at any other front end?
One way is to use below given SQL
SELECT   ( TO_DATE (   TO_CHAR (intime, 'DD-MON-YYYY')
                     || ' '
                     || TO_CHAR (:TIME_VAR, '0000'),
                     'DD-MON-YYYY HH24:MI'
          - intime
       * 24
       * 60
FROM dail_att
WHERE TO_CHAR (intime, 'hh24mi') BETWEEN 0700 AND 0815;*009*

How to acces the filename from Message Header during variable substitution

Hi,
We need to access the attribute filename from Message Header during Variable Substitution.We are able to access the following attributes of 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 we want to specify the interface name from the message header in the target directory or in the file name scheme, we enter message:interface_name as the reference.
In the same way i need to access the filename which we get in the Message Header(which we get in the Message Header when we check the Adaptor specific message properties and filename in sender CC).Any suggestions on the same
Thanks and Regards,
Bhargav

Hi Bhargav,
Use this UDF to retreive the file name from the Dynamic Configuration Payload in the mapping.
getFileName(UDF) -
> Filename(node in the target structure).
public String getFileName(Container container)
   //write your code here
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
return ourSourceFileName;
Create a node in the target structure top hold the filename returned by the UDF.
Now your payload will have the filename along with the actual data.
U can use the variable substution now as u use for the other data in the payload since the filename is now a part of your payload.

Variable substitution in XI (7.0 version).

Maybe you could give us a short hint regarding an error we are getting during the variable substituion in an outbound file adapter.
How can we specify a namespace in the variable substituion?
Without namespace this is working well, but we don't know how to specify the namespace.
We get this error essage: #2006-03-17 15:29:07 CET: Message processing failed: Error during
variable substitution:com.sap.aii.adapter.file.varsubst.VariableDataSourceException: The following variable was not found in the message payload: FileName

We set the flag 'enable variable subsitution' and specified the filename
variable as follows:
FileName payload:ns1:GMPluTxn,1,GMFileHeader,1,FileName,1
The FileName variable is used in the File Name Scheme field:
%FileName%.asc
Thanks in advance.

Give it like this and see if it works
FileName payload:GMPluTxn,1,GMFileHeader,1,FileName,1

Hi Malika,
Do not mention ns1 in the variable substitution.
Why you need to mention the namespace in the variable substitution ?
Just Mention GMPluTxn,1,GMFileHeader,1,FileName,1
Like this.
If you want to get the output file name with namespace, then try to get the namespace as part of your payload(i.e part of your message type ). Then if you don;t want it in the Output file, you can cut it using cut option of File Receiver Adapter.

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.

Variable substitution not working for dynamic file name in Receiver File CC

Hi Experts,
I am doing the scenario of Proxy sender to File receiver and my purpose is to Create the text file
as per the filename available in Source Message payload.
I am using the Variable Substitution method for this as shown below.
Source Message Structure:-
 <Row> -
having Cocurence 1.1
 <Filename> -
having Cocurence 1.1
 <Item> -
having Cocurence 1.Unbounded
 <Field1>
 <field2>
 <Item>
 <Item>
 <Field1>
 <field2>
 <Item>
 <Row>
Target structure is same as the source structure and i have mapped the Filename field of the Source
with the Target structure Filename.
In ID the following is the File receiver CC Configuration.
File Name Scheme:- %Dyn_filename%
In Advance tab, I have selected the Enable option and added one row as Variable name %Dyn_filename%
and Reference as payload:Row,1,Filename,1
In testing I am getting the Error as 'variable Dyn_filename is not found in Message payload'.
Please suggest me.

Jagesh

Hi Pooja,
Hi Pooja,
Thanks for your valuable reply..

'Variable Substitution' error - Expected numeric element index

Hello everyone!
I'm using the 'variable substitution' property in XI to replace the filename of the output file to a value in the message payload.
Here are the parameters I provided:
File Name Scheme: %filename%.xml
Variable Name: filename
Reference: payload:ORDERS05,1,recordset,1,IDOC,1,E1EDK02,BELNR,1
I'm getting this error in the adapter engine:
Caught exception while initializing variable substitution engine: Cannot parse pseudo-path for variable substitution: 'filename': Expected numeric element index, got 'BELNR': For input string: "BELNR"
Can anyone tell me what this means, and how I can fix this problem?
Thanks in advance!
Glenn

Yup, raj! it's IDOC to file.... I did what you asked but I'm now getting this error:
MP: Exception caught with cause com.sap.aii.af.ra.ms.api.RecoverableException: The Adapter Message Property 'FileName' was configured as mandatory element, but there is no 'DynamicConfiguration' element in the XI Message header: com.sap.aii.adapter.file.configuration.DynamicConfigurationException: The Adapter Message Property 'FileName' was configured as mandatory element, but there is no 'DynamicConfiguration' element in the XI Message header
any idea what it means?
Kind regards,
