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.

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.

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

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.

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

AFAIK - Variable substitution does not support attributes. It only support the elements. (- <ns1:batch-info id="test" isTest="true">)
May be you can go with dynamic configuration instead of variable substitution.

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
Manish

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

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.

File Reciver adapter - Variable Substitution

Hi all,
i am creating a file with dynamic file name.
My structure looks like this:
Row - 0-unbound (all the data)
FileName - 1
I don't want the file name to appear in the file I just want it for the Variable Substitution.
so in the content conversion i use only the row.fieldFixedLengths
but in the file i get an extra empty line because of the file name.
Thanks,
Naama.

Hi,
Its better to go for Adapter specific attributes with dynamic configuration. That will avoid you from usage of Filename field in target structure.
Refer - Dynamic Configuration for file name

Steps to read a file through file adaptor and then i need that to insertDB

Hi anyone please help me in reading a file through jdev and then insert into data base i am able to receive the file the null values and getting inserted..
thanks
saileshan.

Hi,
Please let us know the following -
1) Did you verify that you are able to see all the data in the BPEL process from the File which is read?
2) Are you using a transform or an assign activity to insert data into table?
If using a transform activity, did you test the mapping file (.xslt) and see that the transformations are happening correctly?
Let us know the answers to the above questions before we proceed further.
Thanks,
Ritika

Bursting XML Control File - only one variable substitution works

Hello, I have the following from my bursting xml. In my subject I would like to have more than one substitution as in my example. Problem is that when I have more than one, the second one alway is "null". On there own they work fine. Is this a bug/limitation?
<xapi:message id="111" to="${ADMIN_EMAIL}" attachment="true" subject="Unigas Inv
oice No: ${TRX_NUMBER} for ${PARTY_NAME}">

Use this syntax in your burst file (note you will need the above patch applied).
<xapi:document output="${VAR - or hard code name here}" output-type="pdf" delivery="xxx" >
Alternate way (if you don't have the patch) is to use the bursting listener by implementing it and doing the following in the afterProcessDocument interface.
public void afterProcessDocument(int requestIndex, int documentIndex, Vector documentOutputs) {
String outFileName = (String)documentOutputs.get(0);
File newFile;
File oldFile = new File(outFileName);
newFile = new File(oldFile.getParent() + File.separator + "file" + oldFile.getName());
oldFile.renameTo(newFile);
documentOutputs.remove(0);
documentOutputs.add(0, newFile.getPath());
}

File Info and Variable values visible in Sharepoint?

(FM11)
We're considering Sharepoint as a CMS for use with FM11 (maybe FM12 later) and are looking for some trailheads.
Can values of FM variables become visible through Sharepoint?
What about File Info values (File > File Info) ?
Which features of Sharepoint views / pages / layouts are particularly helpful or frustrating?
If you were doing it again, what would you do the same and what would you do differently?

Hi,
It is known issue that on exporting list items, look up column values are lost.
For your issue, you can take steps as below to retain look up column values in export list template:
1. Browse to the source Web’s lookup list “Sub Category” and choose Modify settings and columns.
2. Copy the source lookup list GUID from the URL. It should be a sequence of numbers and letters similar to: %7BFFA47BF8%2D849C%2D4F20%2D9C50%2D173D2F5B6725%7D.
3. Browse to the destination Web’s lookup list and choose Modify settings and columns.
4. Copy the destination lookup list GUID from the URL. Similar as point 2.
5. Delete %2D from the string and replace with a dash sign (-). There should be no dash sign (-) at the start and the end. GUID should be in the following format: FA47BF8-849C-4F20-9C50-173D2F5B6725
6. Save the source Web’s list that contains a lookup column “Category” to the lookup list as a list template called category.stp.
7. Export the list template STP from the source list template gallery to the file system.
8. Rename the category.stp file to category.cab so Windows can open it.
9. Open the file, right click on the manifest.xml file and export it to the file system.
10. Edit the manifest.xml file; find the source Web’s lookup list GUID and replace it with the destination Web’s lookup list GUID.
11. Save the manifest.xml file.
12. Open a VS.NET command prompt.
13. Run the makecab command as: makecab manifest.xml category.stp
14. Import the new STP into the destination Web’s list template gallery. You will need to delete it if it has previously been imported.

Variable Substitution settings for Receiver File Adapter

Hi All,
I wanna use variables for File Name Sheme in the File Access Parameters.I had used by enclosing the variable names within %. When i wanna substitute values for those variables, it is given in the documentation(help.sap.com) that v need to set the Enable indicator. only after setting the indiactor, v can use the variables and can then enter the values for those variables in a table. but i can't see either the indicator or the table in my editor. how can i provide the values for the variables used in file name scheme/Target Directory. and for ur information,i'm using sp12.
any help wud b appreciated.
thnx
