Dynamic File name in FTP Communication Channel

Hi All,
We have requirement where ,we create a filenames dynamically ( runtime).These filenames whihc do change for every execution needs to be added in FTP communication channel.
1. How can we add the this generated file name in FTP CC Communication Channel.
2. Does this file needs to part of target structure during graphical mapping ?
3. Can we also dynamically append the Directory name to file names aswell ?
Please provide your valuable sugestions.
Thanks for your support.

1. How can we add the this generated file name in FTP CC Communication Channel.
3. Can we also dynamically append the Directory name to file names aswell ?
to get the FileName:
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
To get the Directory:
DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","Directory");
Then append:
key+key1
And then in the CC select the Directory checkbox under the ASMA properties...
2. Does this file needs to part of target structure during graphical mapping ?
The file which is sent using the CC will have the FileName as configured in the UDF of the graphical mapping....and if i am not wrong then the target structure resembles the file (if there is no FCC done)....

Abhishek.

Get/put dynamic file name using FTP

Hi Friends,
I am currently using FTP_Connect, FTP_command and FTP_disconnect to get/put a file from a remote server.
But the file name was changed to add a date/time stamp.
So the filename became dynamic (example from 'test.txt' to 'test_200512160800.txt').
I tried using get test. but my FTP command failed. Do you know anyway of doing this?
Thanks.

Issue with file name in receiver Communication channel

Hi Experts,
I am sending the files from SAP Application server to third party Application server.
In my source folder i have different types of files with different names.
but i need to pickup the files which is coming as of type sss_3300_was.txt and sss_3400_was.txt.
what would be the logic for this.what my understanding is if i put sss_* it will works.
If suppose the file is Exist in the folder as sss_3300_was.txt , so it will picked up and places in target folder.
and next time if the file type is sss_3400_was.txt then that will pick up and places in the target folder.
my question is, in the receiver comm channel what would be the file name scheme. i have tried with * and / but system has not been accepted as * can not be given.
Kindly suggest what should i put in Receiver CommChanne file name sheme.
Appreciate your inputs
Thanks,
Bhaskar

Hi Satish,
Thanks for your valuable inputs.
Actually i need to change the subjet when i am asking other question...
first thing is suppose i have 10 files like sss_3100_was, sss_3300_was, sss_3400_was........sss_3900_was in the sender application folder and should be moved to receiver [target] folder with the same name.
as you said mentioned above below is my undertsanding, please correct me if i am wrong.
In sender cc
1. i will give file name as sss_*
2. i will flag ASMA and also check file name.
In receiver cc
1. I will give file name as sss_*
2. i will flag ASMA and also check the file name
The above is my understanding with respect to your inputs, is it correct?
in receiver cc i have tried file name scheme as sss_* but when i see the receiver CC log its telling that * is not allowed.
may be i have not flaged ASMA at that time, but now i will flag ASMA in receiver CC dose it works? just need to confirm from you.
Regarding seconf issue.
when file is picking up from the source folder from SAP Application server as i can see file is picking up well and posting in third party folder and even in the sender cc and receiver cc logs i could see all shown in success.But when i see in the SXMB_MONI in the inbound interface the data are coming in the special charater format like @$??? and so on.But when i checked in SAP Appl server the same file contains the three lines of data like material number purchase order number and so on and it is Text file.
below mentioned are done configs for sender CC by me.
MP: file
TP: NFS [as it is SAP appl server]
filepath:/
file name: sss_*
file type :text
add time stamp
..... and so on
Kindly advise me if any changes are required and also provide me inputs in case any correction.
Thanks,
Bhaskar Reddy

Dynamic file name using FTP adapter

I was trying the dynamic filename scenario taking help from Michal's blog https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/2664. [original link is broken] [original link is broken] [original link is broken] [original link is broken]
If I check the 'adapter specific properties' in both sender and receiver file adapter,then in output I am getting the output filename as same as input filename without using the UDF.
When I used the UDF in mapping,it had absolutely no effect. I am not clear what is the use of the UDF. please let me know where to use the UDF and how to use it.
Thanks
Smith

1. In the mapping program that you are using populate the filename coming from the source into the target in any of the fileds.
2.Sender adapters can write adapter-specific attributes to the message header; these can then be evaluated at configuration time.You can get dynamic filename in UDF in msg mapping....just in ID in comm channel select adapter specific attributes -> filename.....then whatever dynamic name you will create in UDF will be the target filename.....
3. To change the adapter-specific attributes of the message header by using message mappings, you access the required classes of the mapping API by using a mapping runtime constant.
To access the classes DynamicConfiguration and DynamicConfigurationKey by using the mapping runtime constant DYNAMIC_CONFIGURATION, use the method getTransformationParameters() of the container object.
You donot need to hard code the value of the filename in the file adapter for your interface.
In SXMB_MONI, when you see the pipeline services you would see that the value of the filename is populated in the message payload.

Dynamic file name in communication channel

hello
is it possible to give in the communication channel, under the 'File Access Parameters', a dynamic file name?
to get it out of a table or something?
Thanks
Kfir

Hi,
Yes its bit possible to use the dynamic file name at File access paramters
The dynamic filename generation concept is as follows.
In your filename field. just give a variable with % symbols. (eg: %file% ).
Now, under the option Variable Name Substitution, you can give how the value has to be created.
It can be your interface name, sender service name, etc or it can be some value dynamically from your payload.
For the former, your give
message:interface_name ,etc
and for the payload part you give,
Payload: "your element root which u wanna acecss"
Just check this link out,
http://help.sap.com/saphelp_nw04/helpdata/en/bc/bb79d6061007419a081e58cbeaaf28/content.htm
And read the contents under variable substitution and it will help you understand the concepts better.
If you have any clarifications, do get back,
Refer below links for more in depth details about it

How to give a dynamic File Name for Receiver File/FTP Adapter.

Hi Experts,
    I have one scenario in which we are creating a flat file of IDOC which is coming from R/3 & sending it to FTP location. For this we have configured Receiver FTP adapter with File Name Scheme as "NT.out" & in File Consturction mode i have given as "Add Time Stamp".
    therfore while creating a file it is creating as NTyyyyMMdd-HHmmss-SSS.out
where as my requirement is only to to add Time & not the Date. (NThhmmss.out)
    How to do this ?
    for your info we are using ABAP Mapping.
    Pl help me
Regards,
Umesh

Hi Umesh,
      Add one more field to your target structure for your file name and populate that field as per your requirement like NTyyyyMMdd.out. In receiver communication channel use Variable subtiution option and give the refrence of Payload and file construction mode set as create.
And refer the below weblogs for Variable Subtiutuion File Name Scheme
/people/jayakrishnan.nair/blog/2005/06/20/dynamic-file-name-using-xi-30-sp12-part--i - Dynamic File Name Part 1

Dynamic file name while sending to target FTP

Hi Experts,
we have a scenario wherein we are trying to implement dynamic file names.
The scenario is IDOC to file, and we need to append the data corresponding to all the IDOC triggered n a daily basis.
Its like the file abc_01will contain data for day 1(data of oll the IDOC in that day).For day to we need to dynamically name the file as abc_02 and so on.
But before naming the file as abc_02 we need to check if abc01 is present or not .If abc_01 is not present then for day 2 file we need to give the name as abc_01 and so on_.This condition is need to be checked becasue there may be the case that a file may not be picked by the script running at the target system.
can anyone let me know how to check whether file are correctly picked at target.
Regards,
srinivas.

Hi Srinivas,
I think you can achieve this with the next scenario:
- For getting all the Idocs info, you need a ccBPM to collect them, and then, download them to a file.
- To dynamically put the filename, you need to use Dynamic Configuration at the File Receiver Adapter (in the Message Mapping, you can write a UDF.)
- And to check if the daily file exists, you can also write an UDF and then decide the name of the output file.
Hope this helps,
Regards,
Juan

Dynamic File Name depending on the Source File name

Hi Experts,
I have a problem like Dynamic File name depending on the Source File Name. I will explain with example as follwos
Source File name Targer Folder/Filename
NK01.VR59.L2007030 VR59/Rec.l200
NK01.VR71.L2017030 VR71/Rec.l201
NK01.VR77.L2027030 VR77/Rec.l202
See above the exaple, Depending on the Source file name, I am deciding where i need to place my file and what name i need to name it.
So please suggest me the solution and How can i do this with a single communication channel ? Do i need to create multiple CC for each folder??
Points will be rewarded for Valuable anwer.
Thanks in Advance,
Best Regads,

Dynamic file name inside the ZIP file

Hi Experts,
I have done proxy to file scenario, reciever side is the file ZIP file, i have done successfully done Zip file using adapter modules in Communication Channel.
The file name is hard coded like this.
contentType-----Transform.ContentType--
text/plain;charset="UTF-8";name="Billing.txt"
Is there any possible to do dynamic file name instead of hardcoded like add time stamp.
Kind Regards,
Praveen.

hi,
you can always do it using an adapter module like shown in my blog:

Error dynamic File Name in Receiver File Adapter

Hi all,
Dynamic file name for Receiver file Adapter Problem
my multi mapping look like this in design mode
messages
 message1
 SD01_E
 FileName
 row
 message2
 SD02_E
 FileName
 row
by processing the xml look like this:
<ns2:SD01_E xmlns:ns2="urn:lsv.de/SAP/XXX">
<FileName>L40SA939.xiConstant</FileName>
- <row>
or
<ns2:SD02_E xmlns:ns2="urn:lsv.de/SAP/XXX">
<FileName>L40SA939.xiConstant</FileName>
- <row>
in file receivere adapter i have try this but it dos not work
payload:SD01_E,1,FileName,1
Error:com.sap.engine.lib.xml.parser.ParserException: XMLParser: No data allowed here: (hex) 0(:main:, row:1, col:0)
is there any way to have access to Filename in different root elements??
regards
Ralf

Hi Ralf,
i think, you need for each XML msg (each different root element) a new adapter -> a new IF determination, new rec agreement and a new channel.

Sender FTP communication channel

Hi experts,
We have had the following problem twice with two different comm channels:
A sender FTP communication channel stops polling for no apparent reason. There were no errors and the status remained green. After I stopped and started the communication channel in the runtime workbench the adapter picked up all the remaining files and processing finished ok.
Anyone had this problem before? Any ideas for a solution?
Thx,
Philip

Dynamic file name from input payload (RFC 2 flat file)

Hi,
I have an RFC to flat file scenario. The output flat file has not an XML structure, it's just a plain text file generated with abap mapping.
In my source interface (RFC), I have a field called <FILENAME>, I want to use the value of that field to create the target file using dynamic file name. But if in variable substitution I use payload:ZRFC_NAME,1,FILENAME,1 It doesn't work because the dynamic variable substitution try to access to output payload, not the source one...
What can I do?

Hi Marshal,
You can add a extra node to your target strucutre like
FileName- Node
--FileName - Element.
do the mapping from the field filename of RFC to FileName field in u r target strucure. And use this field path at Refrence in variable subtituion.
In the Content converison add the Name & Values as below
FileName.fileldNames -- FileName
FileName.fieldFixedLengths -- 0
FileName.fixedLengthTooShortHandling -- Cut
So the extra field in u r target structure would not populate in u r target text file.
Cheers

Dynamic file name ?

Hi,
I am following this blog to name the target file/directory dynamically at the runtime :
/people/sameer.shadab/blog/2005/09/23/an-interesting-usage-of-variable-substitution-in-xi
But I am getting this error in the CC monitoring :
Could not process due to error: com.sap.aii.adapter.file.configuration.DynamicConfigurationException: Error during variable substitution: com.sap.aii.adapter.file.varsubst.VariableDataSourceException: Unknown message header category 'interface_name ' for variable 'var1'.

Hi,
Try following this weblog for dynamic file name.
/people/michal.krawczyk2/blog/2005/11/10/xi-the-same-filename-from-a-sender-to-a-receiver-file-adapter--sp14
Dynamic filename come under the Dynamic configuration in moni, for your messages.
This is the code used inside.
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;
That is why Dynamic configuration is coming in output.. It is a class to generate dynamic configuration file at runtime provided by SAP XI.
Hope this will help you.

Dynamic file name in case of .txt output files

Hi all,
I have a query related to dynamic file name scenario.
In case of IDOC-XI-FILE sceanrio,
Is it possible to generate .txt file name based on Plant number like
%<Plantname>%_%<BusinessDay>_filename.txt
Note:I have implemneted this for .xml output files but I am not able to implement it for .txt output files .
PLEASE HELP ME .
Regards
Prabhat

Hi Prabhat,
I think, the normal Dynamic File Name generation should work fine in your case also. Even if you perform Content Conversion, you can use Variable Name Substiution to create your Destination file name as, the name of the file is determined first and only then is the content converison perfromed.
for info on content conversion, I would suggest that you go through this thread and check my reply,

Dynamic File name in File Adapter

Hi,
I have a requirement to pass dynamic file name in File Adapter.
Is there any way to pass a variable for the file name attribut in file adapter.
I am looking for some options apart from %yyMMddHHmmss%,%SEQ%...etc
Please suggest if any of you have information on how to put values from a variable to file name attribute in file adapter
regards
Saiju

Hi Saiju,
Yes there is.
Assign your file name to a variable, let's say 'fileName'.
Now go to your invoke activity(for the specific fileadapter) -> Property tab-> find a property call jca.file.FileName -> in the value field assign 'fileName' variable.
That's it... (assuming you are using 11g)
