Variable substitution issue

Hi all,
I've a select against a view (V_XXX) which performs drammaticaly different if run in this two ways:
SQL> SELECT COUNT(*) FROM METOD.V_XXX
2 WHERE MATRICOLA LIKE '%'||LTRIM('310491A')||'%';
--> 50 msecs.
SQL> VARIABLE var VARCHAR2(10);
SQL> EXECUTE :var:='310491A';
SQL> SELECT COUNT(*) FROM METOD.V_XXX
2 WHERE MATRICOLA LIKE '%'||LTRIM(:var)||'%';
--> 17516 msecs.
Explain plain shows that in second case all the joins present inside the wiev are parsed by oracle...whilst it doesn't happen using the direct select.
Thanks a lot for help...
Marco

Optimizer is cost based...
In any case the issue seems to be linked to the presence of db_links.
The issue happens when my select runs against a view (on my 'local' instance) built against three synonyms, all of them are created against remote db objects through db_links.
Building the same view directly inside the remote db and creating a synonym (with a db_link) on my istance, my select has the same performance using a constant or a variable in the where clause (so no issue!).
If someone can explain, what is happening...
Thanks, Marco

Issue with Variable Substitution

Hi,
We have a scenario where we need to use the data from Payload for further processcing of the messeges.The payload looks like the one given below.
<?xml version="1.0" encoding="utf-8" ?>
- <ns1:MT_NOTIFICATION xmlns:ns1="http://WM_ERRHAND" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
- <PROXYRESPONSE>
<STATUS>YES</STATUS>
<NAMESPACE>WM_INVOICE</NAMESPACE>
<INTERFACENAME>MI_INVOICE_MOORE_ACK_IN</INTERFACENAME>
<PROXYNAME>ZXIII_MI_INVOICE_MOORE_ACK_IN</PROXYNAME>
</PROXYRESPONSE>
</ns1:MT_NOTIFICATION>
In adapter, for variable substitution we have specified as below:
payload:MT_NOTIFICATION,1,PROXYRESPONSE,1,NAMESPACE,1
but getting an error "Message processing failed: Error during variable substitution: java.text.ParseException: Variable 'namespace' not found in variable substitution table"
Is the variable that we have declared is right or is there anything we have missed out. Any helpful answers will be rewarded
Thanks and regards,
Ram.

Hi Ram,
The substitution looks fine.
Did you read this,
<i>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 ...</i>
Try seleting this option and checking the same.

Filename in J2SE Adapter with Variable Substitution

Hello,
Within the J2EE receiver fileadapter (and ftp) from SP13 it is possible to compose the target filename and directory based on the payload of a message using variable substitution.
I wonder if it is also possible to use variable substitution with the J2SE fileadapter. For this it is not documented but i thougth that the same java libraries are used for the J2EE an J2SE file-adapters.
Aybody??
Really Nobody??

Hello,
the J2SE Adapter does not support variable subsition. Therefore we created our own class which gets called from the main SAP XI class "XMB2FileProcessor.class" wich is in the jar "aii_msg_adapter.jar". In your own class you can do what ever you need to chane the file name. In the configuration you can set your own parameter to search the payload for a string you want to replace. We also had to come up with our own timestamp, e.g. file2005-11-10 which SAP does not let you do, only the full timestamp is possible.
One other nice thing is that you can develop our JAVA class local and test it with your local J2SE Adapter Engine on you PC before you deploy it.
Steps to do:
1. JAD the SAP class
2. Put a call in the SAP class
3. Compile the class
4. Put the class back in the archive
5. Create your own class
6. Create a jar file for it
7. Put the jar file in the tech_adapter directory
8. Change the run_adapter start cmd to include your jar file
It works great, the only issue is if you patch the J2SE engine you have to do step 1 to 4 again but that should it very easy to do.
Cheers

Error in Variable Substitution

Dear All,
Result Payload:

</ns1:MT_Level1>
I want to use "File Name" in the "File Node" node for my variable substitution.
In the configuration:
File Name Scheme = %filename%
Variable = filename
reference = payload: Messages, 1, Message, 1, MT_Level1, 1, FileNode, 1, FileName, 1
Note: I'm using multimapping (1 to N).
File Name path is /ns0:Messages/ns0:Message2/ns1:MT_Level1/FileNode/FileName ( from right click in the file name --> copy path).
I got following error:
"Attempt to process file 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: filename"
Please advise!
Best Regards,
Victor.

Dear All,
My problem is solved!
The issue is because I don't put the interface mappings sequence as the same sequence as the message mappings sequence. Hence the structure name that i put in the variable substitution all are not match with the structure name in the payload even though all have the file name element.
So what i did is i have to reorder the sequence of my message mappings to be the same sequence as the interface mappings sequence.
Thanks for all that trying to help!
Appreciated it guys.
BTW, for the variable reference it's correct that i no need to put message and message2 as the reference.
payload:MT_Level1,1,FileNode,1,FileName,1 will do.
Best Regards,
Victor.

Variable Substitution in Receiver File Channel

Hi All,
Could you kindly help me with this?
Mine is File to File Scenario. ECC drops a XML file in AL11 directory and i send that file using FTP to a third party system. There is no mapping involved and i use ICO. I need to get a value from the payload dynamically for using it in my file name.
When i tried to use Variable Substitution Method i get this error : VariableDataSourceException: Caught SAXException while parsing XML payload: Content is not allowed in prolog.
This is the reference i have given in my variable substitution : payload:customerelement,1,customer,1,sender,1,dealercode,1
and my XML structure is as below and i am trying to access the dealercode field in the XML.
<?xml version="1.0" encoding="UTF-8"?>
-<ns0:CustomerElement xmlns:ns0="http://www.xxxxxx.com/customer">
<recordCount>34</recordCount>
<Customer>
<Sender>
<transmitDate>ddmmyy</transmitDate>
<dealerCode>N050</dealerCode>
<DMSSystem>ABC</DMSSystem>
<DMSReleaseNumber>1.0</DMSReleaseNumber>
</Sender>

Hi Amit,
Yeah that is correct. But in my case the XML structure was not properly formed and i hwas frequently getting this error " Content is not allowed in Prolog" for which i tried all the solutions in SDN and nothing worked out. So i had no other option and had to go for adapter module.
Now the issue is solved and the interface is working as expected with the adapter module.
Thanks for your valuable inputs.

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.

Sender_interface_name in Variable Substitution in Receiver File Adapter CC

Hi,
as per this page : http://help.sap.com/saphelp_nw04/helpdata/en/bc/bb79d6061007419a081e58cbeaaf28/frameset.htm
it says:
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_hex
Can we not access sender_interface_name and sender_interface_namespace are not mentioned in above list of variables.
Is it not possible to access sender_interface_name or sender_interface_namespace as variable substitute parameters from within Receiver File Adapter Communication channel.
thanks.

Yes, i can hardcode, thats not a bad idea, i need to create then 3 different Reciever File Communication Channel objects, as I am dealing with 3 scenarios for which sender system and sender interface is different.

yes in this link you provided i can see..
INTERFACE     Interface
INTERFACE_NAMESPACE     InterfaceNamespace
SENDER_SERVICE     SenderService
RECEIVER_SERVICE ReceiverService
RECEIVER_NAME     ReceiverName
RECEIVER_NAMESPACE     ReceiverNamespace
it seems both INTERFACE (,INTERFACE_NAMESPACE) and RECEIVER_NAME(,RECEIVER_NAMESPACE) are present, may be one is for sender, and another is for receiver.. may be if i use dynamic configuration, possibly my issue would be addressed.. correct me if i am wrong.
thanks.

Error during variable substitution: idoc to file

Hi Friends,
I have a got a issue which is Idoc to file scenario.
Iam getting the following error.
Attempt to process file 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_processing
Could you please tell me waht could be the reason for the same?
as per my analysis, I observed that the field date_processing has been declared

Hi Sandeep ,
If the variable date_processing refers to an element in XML schema, Please check if you have added 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,....
Where 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.
Also please check

SFTP Variable substitution error.

Hi,
my scenario is file to sftp fcc.
I have successfully configured the modules and able to put the ouput fcc file inthe target sftp directory,
But when implementing variable substitution i am facing issues getting error as
Error: com.aedaptive.sftp.adapter.exception.VariableSubstitutionException : Error during variable substitution: the following variable was not found in the message payload: var1

Unable to find where the error is when i configured through file adapter its working fine.
Thanks,
--Kishore.

HI,
your variable declartion is perfect, can you please check the below points,
   1.To specify variables in the target directory and file name scheme, they must be enclosed by % characters.
   2.variable name is case sensitive, can you give only lower case instead of giving upper case.
   3. Model_Number is giving same as per the message type.
Please look below link.

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 !!

Variable Substitution for Source Directory

Hello,
I have seen several threads about using a UDF and variable substitution for dynamically determining the Target Directory.
Is anyone familiar with (or had to implement) a solution where the Source Directory is dynamically determined.
My challenge is to connect to a different Source Directory name (sy-datum format, ex: 20070920 ) each day on an ftp site and download all the files in the folder to a know target directory. I am doing a simple file-to-file transfer, so no mapping is involved.
Your comments, suggestions and feedback is greatly welcomed.
Thanks,
Ralph

Hello Carme,
I have not found a solution for this type of event.
I was attempting this because the FTP site I was connecting to would DELETE a file the moment XI touched it. So when XI (using FTP Transfer protocol) configured with a DELETE or ARCHIVE (Processing Mode), it would error off because the file was no longer on the FTP site. I contacted the site but they refused to deactivate their script to auto-delete files. Using TEST processing mode is not recommended per SAP in a server pool environment. You would think SAP XI would provide a fourth option in which a DELETE command is not issued back to the FTP site.
The FTP site did have sub-directories in which copies of the original files were stored, but I could not figure out how to dynamically change the XI Source Directory as the current date changed.
I settled on using File NFS (Transfer Protocol) and running the FTP commands from a .bat (batch file). I put the command I run down at the bottom of the XI page with a 60 second timeout.
I still do not change to each folder dynamically because the standard FTP (GET and MGET) commands do not attempt a Delete after file retrieval.
Perhaps using a batch file is an option you may want to consider using.
Cheers,
Ralph

Variable Substitution for File Name Scheme

Hi all,
Please clarify the following issue.
I have two source fields
Transfer Order number - 0000000222
Transfer Order line item - 0001
Both i map it into one target field
The target field output is - 0000000222#0001
I need a file name which starts with ABC <TranferOrderNumber>.txt
The problem is, when i try to use payload i get output
(ABC0000000222#0001.txt). The reason is i use the target field which was concatenated. I don't have any target field with only transfer order no.
Please give me a solution where i would get output
(ABC0000000222.txt).
Thanks in advance,
Jose Augastine

Hi,
Other way may be like this ..Create a one more segment in your target structure with field name as Transfer Order No. And populate only this no. And in the Reciever File adapter , in the variable sub, use only this field. But this new segment will come in the file. To avoid this, you can make use of " Cut " Parameter in the File Content Conversion.
This will hold good, if you have content conversion-

Variable substitution or dynamic configuration

Hi,
   I am doing Proxy sender to File receiver scenario. I have message payload like,
MTtest1..... 0..1
date.... 0..1
item....0...unbound
I want to create a text file with the name SAP<date>.
I am using a variable substitution method, date: payload: MTtest1, 1, date, 1
Target directory: SAP%date%
I am getting the filename correctly, But this creates a blank line in the top of the file. Please suggest me how to overcome this issue.
If a send the date at the end, how the it must be written in variable substitution method.
If I need to use dynamic configuration, please tell me how to do that, i saw few blogs, but i am not able to get it.
Thanks and Regards,
Sri

Dear Arunsri,
Better to use Dynamic Confi method becs its recommended by SAP also.
Please Follow the below steps.
(1)Create the UDF and pass Filename as an Input parameter as shown here.
public String Set_Output_File_Name(String var_Filename, String var_Directory, Container container) throws StreamTransformationException{
DynamicConfiguration conf = (DynamicConfiguration) container
    .getTransformationParameters()
    .get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
conf.put(key, var_Filename);
return "TRUE";
(2)In File receiver adapter configuration, select the Adapter Specific message attributes and in that select the Filename Option.

Query reg Variable Substitution with enhanced interface mapping

Hi All,
The scenario is IDoc to file using enhanced interface determination (message split based on some conditions) and the output file name should be based on a field value in the IDoc. So, I've tried using Variable Substitution Option in the receiver file adapter. But it's failing with the error 'com.sap.aii.adapter.file.varsubst.VariableDataSourceException'.
My question is does Variable Substitution works with Enhanced Interface Determination? Bcoz the outcome of interface determination is a main and sub payload.
IDoc Payload
<?xml version="1.0" encoding="utf-8" ?><HR_HRMD_A07><IDOC BEGIN="Constant"><E1PLOGI SEGMENT="Constant">
<E1PITYP SEGMENT="1"><E1P0000 SEGMENT="1"><ENDDA>99991231</ENDDA></E1P0000></E1PITYP></E1PITYP></E1PLOGI></IDOC></HR_HRMD_A07>
Variable Substitution XPATH, which I've mentioned is payload:HR_HRMD_A07,1,IDOC,1,E1PLOGI,1,E1PITYP,1,E1P0000,1,ENDDA,1
Thanks in advance.
Regards,
Joe.

Hi,
It was the problem with the capital letters for the variable field. We changed it to small letters, then the issue is resolved.

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
