Abap mapping and variable substitution in File adapter

Hi experts!!.
I am new in abap mapping, but I can do one abap mapping succesfully, but my problem is:
I need to do a variable substitution in my file receiver adapter:
Target directory = %cliente&/out
File Name Scheme = TC%Fecha%.EFI
¿Using abap mapping is this possible? How I can do it?.
Please is very urgent.
Thanks in advance, and best regarts.

Yes you can,.
DynamicConfigurationKey key = DynamicConfigurationKey.create(
    http://sap.com/xi/XI/System/File,
    FileName);
will become
DynamicConfigurationKey key = DynamicConfigurationKey.create(
    http://sap.com/xi/XI/System/File,
    Directory);
In the receive file adapter all you would need to do is select Adapter Specifc Attributes --> File Name and Directory and givce some dummy values for the filename and directroy. In the runtime values will be taken from the SOAP header which you set in the mapping.

Problem in Variable Substitution (Receiver File Adapter)

Hi,
I am facing problem in the variable substitution in receiver file Communication channel. My expected file name is A_C.xml; but my actual output filename obtained is C_C.xml for the below example target file:
<ProductionSch>
<CustomField>
<value>
<ValueString>A</ValueString>
</value>
</CustomField>
<CustomField>
<value>
<ValueString>B</ValueString>
</value>
</CustomField>
<CustomField>
<value>
<ValueString>C</ValueString>
</value>
</CustomField>
</ProductionSch>
I have used the following parameters in the file communication channel:
File Name Schema: %var1%_%var2%.xml
Variable Substitution:
Variable Name Reference
var1 payload:ProductionSch,1,CustomField,1,value,1,ValueString,1
var2 payload:ProductionSch,1,CustomField,3,value,1,ValueString,1
When I try using either of the one in the file name schema and the corresponding variable reference in the variable substitution I am getting the correct output filename as A.xml or C.xml. However, when I give either of the one variable in file name schema and both the variable references in the variable substitution I am getting only C.xml as per the example file.
Can any of you suggest me where I am wrong or any other suggestion which I can try?
I cannot use dynamic configuration as I am using multimapping. Multiple file names cannot be generated using dynamic configuration.

hi Sowmya,
refer you to this [Note 1581988 - Variable Substitution option does not work properly|https://service.sap.com/sap/support/notes/1581988] (2011.05), as SAP says " when there is more than one variable using the same name as the last element, File Adapter does not select the correct one.... ".

IDoc to File - IDoc number : Variable substitution in File Adapter

Hi,
I have an IDoc to File scenario. I want to use the IDoc Number as part of the target filename (using variable substitution) in the File Adapter. However, the target flat file does not have a field where I can store the IDOC number. I know the IDoc number is also stored in the message header ( under the IdocInbound tab), but is there any way I can access this in the variable substitution?
Failing this, if I have the Idoc number in the target XML, is there any way I can skip it in the flat file generated?
example...
XML looks like this...
<Root>
<Record>
 <IdocNum>99999</IdocNum>
 <HeaderRecord>
 </HeaderRecord>
 <LineRecord>
 </LineRecord>
 <LineRecord>
 </LineRecord>
</Record>
</Root>
But the flat file should be..
HeaderRecord...
LineRecord...
LineRecord...
Cheers

Hi Chandra,
Thanks for this
But this is standard stuff that is detailed in SAP help files (http://help.sap.com/saphelp_nw04/helpdata/en/bc/bb79d6061007419a081e58cbeaaf28/frameset.htm)
What I was looking for was in Sravya's blog (refer the earlier entry).
Thanks anyway

Blank Lines at end of file when using Variable Substitution in File Adapter

Hi all,
I'm using variable substitution in a File Adapter, it's refers an element of message, like:
filename payload:MESSAGE_INTERFACE,1,FILENAME,1
The variable substitution is working right, but it's append a BLANK LINE at end of file.
Anyone knows how to solve this problem ?
Thanks in advance.

Hi Regis,
I suppose you're using content conversion?
if so try adding
endSeparator = '0'
to your last element
this will delete the default line break at the end

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-

Hi
Mapping Techniques
XI provides 3 standard ways of interface mapping between source and target.
Graphical mapping
Java Mapping
XSLT Mapping
Two more additional mapping types can be activated in XI by making changes to the exchange profile. Those two mappings are
ABAP mapping
XSLT mapping with ABAP Extensions
Graphical Mapping
Graphical mapping is a common approach followed by everyone for generating desired target structure. It involves simple drag-n-drop to correlate respective nodes (fields) from source and target structure. It hardly involves coding. (Exception - User defined functions). But sometimes with graphical mapping it is difficult to produce required output. For example ... text/html output, namespace change, sorting or grouping of records etc.
ABAP Mapping
A person comfortable with Object Oriented ABAP can go for ABAP mapping instead.
Java Mapping
Java Mapping uses 2 types of parsers. DOM and SAX. DOM is easier to use with lots of classes to help you create nodes and elements, but , DOM is very processor intensive.
SAX parser is something that parses your XML one after the other, and so is not processor intensive. But, it is not exaclty easy to develop either.
XSLT Mapping
One can also think of Java mapping as another option but it is a bit complex and required knowledge of Java. In such cases, XSLT mapping can be the best approach to meet the requirements.
A few example cases in which an XSLT mapping can be used:-
When the required output is other than XML like Text, Html or XHTML (html displayed as XML)
When default namespace coming from graphical mapping is not required or is to be changed as per requirements.
When data is to be filtered based on certain fields (considering File as source)
When data is to be sorted based on certain field (considering File as source)
When data is to be grouped based on certain field (considering File as source)\
Advantages of using XSLT mapping
XSLT program itself defines its own target structure.
XSLT programs can be imported into SAP XI. Message mapping step can be avoided. One can directly go for interface mapping once message interfaces are created and mapping is imported.
XSLT provides use of number of standard XPath functions that can replaces graphical mapping involving user defined java functions easily.
File content conversion at receiver side can be avoided in case of text or html output.
Multiple occurrences of node within tree (source XML) can be handled easily.
XSLT can be used in combination with graphical mapping.
Multi-mapping is also possible using xslt.
XSLT can be used with ABAP and JAVA Extensions.
Disadvantages of using XSLT mapping
Resultant XML payload can not be viewed in SXMB_MONI if not in XML format (for service packs < SP14).
Interface mapping testing does not show proper error description. So errors in XSLT programs are difficult to trace in XI but can be easily identified outside XI using browser.
XSLT mapping requires more memory than mapping classes generated in Java.
XSLT program become lengthier as source structure fields grows in numbers.
XSLT program sometimes become complex to meet desired functionality.
Some XSL functions are dependent on version of browser.
Different types of Mappings
MAPPING SUPPORTED BY XI
Message Mapping -> Graphical Design and testing environment. Default Provided By XI. Queue based modelling allow handling or large documents. Extensible via user defined functions
XSLT Mapping - > Based on openstandard, Portable across application platform, Extensible using user defined functions kewl but disadvantage is Memory overload while handling large documents.
SAX -> Simple Api For XML. -> Allows you to parse through a XML document. Doesn't consume any memory. But the message can be parsed only once from top to bottom. It Has evolved by contributions made by group of ppl itz a open architecture.
DOM -> Document Object Model -> Itz designed by W3C. Consumes Memory as the message will be loaded. Allows parsing of document in both way top down and bottom up.
Send me your email id.Shall send you very good docs for both ABAP Mapping and message mapping.
Thanks

Multi-Message-split with ABAP mapping and adapter specific attributes

Hi all,
With ABAP-Mapping I split 1 message to n messages.
So many files are generated in file-Adapter.
Everything fine.
But now I want the file names different using adapter specific attributes.
It is not possible to use variable substitution and write the file name in payload because of receiver restrictions.
I tried this with following similar coding in ABAP-Mapping:
data: lt_records TYPE MPP_DYNAMIC_TAB.
 Loop.
 l_file_name = "payload-Inbound"-information
 ls_record-namespace = 'http://sap.com/xi/XI/System/File'.
 ls_record-name = 'FileName'.
 ls_record-value = l_file_name. "l_file_name comes from inbound-payload
 append ls_record to lt_records.
 Endloop.
CALL METHOD dynamic_configuration->set_all_records
 EXPORTING
 records = lt_records.
If I start the interface I see in the monitoring the dynamic configuration with many entries for file-name in the the SOAP-Header mapping of the request message (following extract):
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- 
- <SAP:DynamicConfiguration xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
<SAP:Record namespace="http://sap.com/xi/XI/System/File" name="FileName">BPAADDRESS.XML</SAP:Record>
<SAP:Record namespace="http://sap.com/xi/XI/System/File" name="FileName">BPABROKERROLE.XML</SAP:Record>
<SAP:Record namespace="http://sap.com/xi/XI/System/File" name="FileName">BPACOMPANYSEGMENT.XML</SAP:Record>
<SAP:Record namespace="http://sap.com/xi/XI/System/File" name="FileName">BPACUSTOMERROLE.XML</SAP:Record>
The result is that all files have the same file name (last entry in dynamic configuration).
Is it possible to write the adapter specific configuration in ABAP-mapping for every single result message??
Thank you for your help,
Florian

Hi Florian,
I've a different idea...I dont think its a "right solution" but just another work around..it involves a BPM...
In your ABAP mapping..set the dynamic config with as many variables as number of different messages...i.e. use the variables like 'FileName1', 'FileName2'...'FileName6' instead of 'FileName'. But use the same namespace 'http://sap.com/xi/XI/System/File'
Call the above mapping in a BPM and capture the individual messages and set the attribute 'FileName' from the values of 'FileName1' to 'FileName6' accordingly using Message Mapping and then send the message using the 'Send' step.
before you try this, try using the variable names 'FileName1' ...'FileName6' in the receiver adapters...enable the ASMS. I know we need to select which variables from the dynamic config to be used by the adapter by specifically selecting 'FileName', 'Directory' etc...but just give it a try and see if it works..
Or..instead of using a BPM..you can combine Henrique's idea...use Adapter module to set the value for 'FileName' from variables 'FileName1'...'FileName6' accordingly.
hope I'm clear..lemme know if you have any questions..
cheers

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
MP

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.

Dynamic file and variable substitution

Hi Experts,
I am working on a scenario where filename is reading from payload.based on header value ,i am creating file along with item records.I did variable substitution also.whenever header value changes ,a new file shud be created.
I placed two records in my input message...
<ns1:MT_DC_Send xmlns:ns1="http://urn:psr/ff/DC">
 <Source>
 <FName>XYZ</FName>
 <FType>F</FType>
 <Input>Item1</Input> </Source>
 <Source>
 <FName>ABC</FName>
 <FType>F</FType>
 <Input>Item2</Input>
 </Source>
 </ns1:MT_DC_Send>
but only one file is getting created with name XYZ.txt(I used cont conversion)
output fiile data is

Item1
Item2

File adaptor and variable substitution

i have used variable substitution in the reciever comm channel to dynamically alter the folder ...Question is ..is there a way to do this from the sender comm channel..
I know, i know we can write a custom module..etc..etc..
I mean besides that ..is there a way sap provides out of the box...
Michal..what do you think..?
PS: your blog on var subst is very good !
Regards
Venkat

Hi Venkat,
For implementing variable substitution on the sender side. you can develop your own module as per your requirement.
Only question is you can easily implement this on receiver side receives payload information coming after the mapping. While processing communication channel, it has payload to refer for variable substitution..
While on the sender side communication channel do not have payload to implement variable substitution.
Can you explain in detail about condition you want to apply in variable substitution.

Date and Time in Sender File Adapter Target Directory

Hi there,
is there a way of using Date and Time from XI to the Target Directory naming? To use variable substitution some fields of the message had to contain that date and time information, which is not our case.
For filename you can use "add time stamp" option, but and for target directory?
Thanks and regards,
Henrique.

Hi there, Moorthy
We've tried to write that shell script that you mentioned, but now we have a few doubts on how to make it create the proper directory.
In the file adapter, my target directory is "/%var1%/%var2%/", where %var1% and %var2% are variable substitutions, referencing data which comes from the payload. Now, I need the shell script to append "/<Year>/<Month>/" in the target directory. But where to archive the script? If it stays in the root directory, than how to make it create "/<Year>/<Month>/" folders inside a directory which is variable (/%var1%/%var2%/)?
Is there a way of passing %var1% and %var2% as parameters for the shell script?
Thanks a lot,
Henrique.

Physical path and Logical name in File adapter

Hi All-
I am using a file adapter, in which i need to specify the physical path or logical path.
In dev environment my file adapter's input path is /c01/interface/dev/input, but in my test environment it is /u01/interface/test/input.
So everytime I have to change the path and deploy it in two different environment.
I am using unix environment, is there any way i can use some environmental variable $INPUT_DIR and use it in logical name so that in logical name i can use as $INPUT_DIR/input, where in dev $INPUT_DIR will be /c01/interface/dev and in test environment it is /u01/interface/test.
I have tried this but there is still some probelm, I want to know is the approach I am using is correct? or is there any other solution for it?
Regards,
Sreejit

Hi,
1. physical name: use a specific directory (e.g. /u01/....
2. logical name: use a LogicalDirectory like "InputFileDir" and rewrite this inside the bpel.xml

ABAP Mapping and Message Mapping

Hello
I want to do the followig mapping
File - > IDOC
field1 ->field_idoc1
field2 ->field_idoc2
field3 ->field_idoc3
field4 -> (based on an dictionary table in the R/3)
For the first 3 fields I will use message-mapping.
For field4 I heard about ABAP Mapping. Select with the value of field4 in an ABAP Table and response the new value to the mapping back.
Would both mappings in one Interface-Mapping work?
Regards
Christoph

Christoph, There was an article previously available in articles section, now i dont find the link.
I have given a sample code below. You can find lot of sample JCO code provided along with the JCO library that can be downloaded from service.sap.com.
JCO.Repository mRepository;
JCO.Client mConnection = JCO.createClient(
               sapClient,
               userName,
               password,
               language,
               hostName,
               systemNumber );
// connect to SAP
mConnection.connect();
// create repository
mRepository = new JCO.Repository( "sample", mConnection );
// Create function
JCO.Function function = null;
IFunctionTemplate ft = mRepository.getFunctionTemplate("Z_TEST");
function = ft.getFunction();
// Obtain parameter list for function
JCO.ParameterList input = function.getImportParameterList();
// Pass function parameters

Need to get file name and directory back from file adapter - WRITE

I am using the file adapter to write a file. I want to log the file name of the file we just created. Since we use a precise timestamp in the file name, I can't accurately guess.
I have an invoke in my BPEL process to the file adapter. My first try was to assign the jca.file.FileName property to a variable, but it never comes back. I looked around and saw plenty of ways to SET the file name for a write and GET the file name for a read, but no GET file name for WRITE.
Anyone have a solution?
Thanks in advance!

I think I got your point... You can tell FileAdapter the filename to write, but if you don't then FileAdapter can not tell you the filename that it wrote... I think it is pretty possible Oracle didn't implement the latter, as the write operation is probably asynchronous and the filename is calculated later on...
If what you want is just log, you may achieve your requirement by increasing verbosity on Adapter logs... Have a look at the link bellow...
http://docs.oracle.com/cd/E15586_01/integration.1111/e10226/ad_mon.htm#CJHHBBID
Otherwise, the solution for you will be to calculate filename yourself, and that will be a little bit of reinventing the wheel... But at least you will know the filename...
Cheers,
Vlad

SQL Injection and variable substitutions

Hello helpful forum, I'm trying to understand what really goes on "behind" the scenes
with the variable substitutions in order to protect from sql injections.
I'm using apex 3.0.0.00.20
The trickiest component seems to be a Report of type "pl/sql returning sql", since
multiple dynamic sql interpretations are done there.
consider the following innocent looking disaster:
DECLARE
l_out VARCHAR2(2000);
BEGIN
l_out := 'select * from test_injection t where t.name like ''%' || :NAME || '%''';
RETURN l_out;
END;
if NAME is a single quote the report will return:
failed to parse SQL query: ORA-00911: invalid character
which hints to the fact that NAME is not escaped, and you are in fact able to access db functions
as in: '||lower('S')||'
I also tried to put there a function that runs in a autonomous transaction to log its calls, and
I see that it's called five times for each request.
consider now the similar solution (notice the two single quotes):
DECLARE
l_out VARCHAR2(2000);
BEGIN
l_out := 'select * from test_injection t where t.name like ''%'' || :NAME || ''%''';
RETURN l_out;
END;
with this second example nothing of the above is possible.
So my theory (please confirm it or refute it) is that there is a first variable substitution done
at the pl/sql level (and in the second case :NAME is just a string so nothing is substituted).
Then the dynamic sql is executed and it returns the following string:
select * from test_injection t where t.name like '%' || :NAME || '%'
now another substitution is done (at an "APEX" level) and then query is finally executed to return
the rows to the report.
The tricky point seems to be that the first substitution doesn't escape the variable (hence the error
with the single quote), while the second substitution does.
Please let me know if this makes sense and what are the proper guidelines to avoid sql injection with
the different kinds of reports and components (SQL, pl/sql returning sql, processes, ...)
Thanks

Giovanni,
You should build report regions like this using the second method so that all bind variables (colon followed by name) appear in the resultant varchar2 variable, l_out in your example, which will then be parsed as the report query. This addresses not only the SQL injection problem but the shared-pool friendliness problem.
