File Adapter Acknowledgement in BPM

Himadri,
You cannot achieve this unfortunately
Reason is that file adapter supports only Transport Acknowledgements. What this implies is that the BPM checks only if the message is sent from the BPE to the Adapter Engine Successfully. It does not check to see if the file is written in the target destination.
Just try this, give an incorrect folder ( or something of this sort ) in the file adpater and try Transport Acknowledgement. Wrap this around an exception block. You will be surprised that the exception block is not called.
Reason like i told is that the BPE thinks it is successful as the message has been passed to the adapter engine.!

Bhavesh

Sandro,
Thanks for that input. Actually tried the same on my XI box and what you have told is absolutely correct.
Until the transport acknowledgement is not received for the first send step, the next send step will not be called! I seem to have forgotten something somewhere or my observation which I had given earlier was with respect to some othe scenario which am not able to recollect!
Himadri~~ Apologies for the incorrect answer. Transport Ack's should do the trick for you like correct pointed by Sandro.
Thanks,
Regards

File Adapter Acknowledgement in BPM - NEW Question

This is in cntinuation of my earlier question:
File Adapter Acknowledgement in BPM
Now I understand that the send step should wait to get the acknowledgement from file adapter.
As I understand This ack may be +ve or -ve.
So my question is how do we test for + ve acknowledgement in the next step / switch?
Thanks,
HImadri

hi,
in condition editor of this switch step you need to choose technical objects
and check it they = true
for sender apps
you can also use Main/MessageClass field
have a look at the bottom of this page to
check their values:

Acknowledgement from receiver file Adapter with out BPM

Hi Gurus,
I am trying to get Acknowledgement from Receiver file Adapter with out Using BPM.
Here is the scenario. I am sending files from different Sender Adapters. There is only one target that is File Adapter. After each successfull and failure transaction I need an Acknowledgement that needs to trigger another receiver adapter and send the the file name and timestamp to that file.
Hope this is a complicated scenario. Please help me.
Thanks,
Kevin

from sap note 821267
6. Acknowledgements
    * Q: Does the File Adapter support acknowledgements?
    * A: You need to distinguish system acknowledgements (indicating that a message has been received by the target system) and application acknowledgements (indicating that the message has been successfully processed by the application on the receiver side).
           The receiver of an XI message will only send an acknowledgement back to the sender if the sender has requested one. However, the File Adapter has no functionality that relies on the receipt of an acknowledgement, so it never requests one.
           On the other hand, if a File Adapter Receiver receives a request to send an acknowledgement, it will do so for a system acknowledgement request. Application acknowledgements are not supported at all as the File Receiver has no way to determine if the written file has been correctly processed by the back-end application, which is what a positive application acknowledgement would imply.
this means that your requirement is ideally not possible without a BPM

File adapter instances for BPM processing

I have two doubts. If I have a single file adpater polling an Input folder and the reciever is the BPM,and i have multiple files in the same folder to be picked up by the File adapter. Will the files be qued up to be picked by the file adpter, or will there be a multiple instances of the file adapter internally ?
The second issue is that, if i have multiple instances of BPM using the same outbound file adpater, then will the outbound messages be qued up or sent parallely
Please share any ideas on this.
Regards

Hi,
1) Files with the same name cannot be in 1 folder. so if you need to pick up (say 3 files) u need to create 3 File sender channels and associated these channels to the corresponding sender agreements. So when ever an adapter find sthe file it will pick it up. So there will be queuing up at Adapter level.
2)In the secod case, all instances of BPm will send to the same file adapter, and the files will get overwritten unless you specify somethign like "append messad" or "add time stamp"
3)Each instance of your BPM is an indivual process. It doesn't care if the instace1 RFC has been suceessfully processed or not. So when file2 is sent, BPMInstance2 is created and RFCadapterInstance2 gets started processing....
Hope this helps you.
Cheers,
Siva Maranani.

File Adapter Acknowledgment

Hi,
My scenario is Proxy -> PI -> File
I am returning an acknowledgment but we have a strange problem. At first when the scenario was successful it was returning code (status) 77 and when there was a error it returned code (status) 75. But know when we test it, it returns 75 but the scenario is successful. The file gets written to the FTP.
Has anybody more knowledge on these status codes and on file acknowledgment?
Best Regards.

My mistake. It returned "0", meaning no acknowledgement yet received.

Schedule file adapter

Hi All,
 Is it possible to Schedule file adapter without using BPM.
 Ex for same scenario:
 file 1
 field 1 = 'a'
 file 2
 field 1 = 'b'
I want to post 'file 2' only after 'file 1' successfully posted in SAP.
If 'file 1' not posted successfully then 'file 2' will not post and wait in XI for 'file 1'.
Note:Thease two file's using same Message Type in SAP, i.e. both are belong's to same scenario's.

As Udo said it is not possible without using (as of now).
If you have not seen these docs, check them out.

Acknowledgment in File Adapter

Hi,
I tried a BPM that receive from a SOAP and
writes into a file. I need BPM because of
alerts.
Because I started a s/a-bridge, I would like
to send the soap adapter a response (like an
errorcode). The sender step got a field
Acknowledgement. How can I use this? In SAP XI
documentation it says that the receiver got to
send an acknowledgement, but I can't find how
a file communication channel can send an acknowledgement.
Any experiences??
thanks
chris

I think there would be an alert if the file adpater
could not reach the file system if I build my
integration prozess like this:
-> block with exception -> open s/a-bridge -> send to file -> close s/a-bridge
The exception should close process with a control step.
So, if I would like to close the message with a message that included an errormessage field and fill this field with a constant, how can I do this? Do I have to add a transformation step?
I have:
Message-types:
- a request for soap
- a response for soap
- a request for file (it's not necessary, but I would like to split of web service from writing structure)
Interface:
- a sync out for web service
- a sync abs for BPM
- a request abs for BPM (web service)
- a response abs for BPM (web service)
- a request abs for BPM (file)
Mapping:
- sync out to sync abs (web service)
- request abs (web service) to request abs (file)
- ??? One for mapping constant into repsonse?
how can I do the mapping of the constant, if I don't
have a file response??
thanks

Setting directory dynamically in File adapter in BPM 11g

Hi,
I am using file adapter in BPM 11g for writing perpose. While configuring, it is required to provide the directory location, which can be either physical path or logical. The location where the new file will be stored/saved is written in a text file. I want to fetch the location from that text file and want to store the new file in that particular location at run time. Please help !!!!

Hi,
You can dynamically set -among others- the outbound directory and outbound file name for a File Adapter. See: http://download.oracle.com/docs/cd/E17904_01/integration.1111/e10231/adptr_file.htm#CIACICFD. If you need to retrieve the information beforehand from another file, you could use a synchronous read. See: http://download.oracle.com/docs/cd/E17904_01/integration.1111/e10231/adptr_file.htm#BABDCEBE.

Problem receiving acknowledgement: abap proxy == file adapter

Hi experts,
I am developing an asynchrone interface using PI 7.0. The scenario is: SAP ==> FILE.
In SAP I have created an abap proxy in wich I requested an acknowledgement when calling from the abap code. In PI I have created an Integration Process with a receive step, and a send step. In de send step I am asking for a transport acknowledgement.
When I test the interface and I look in the SXMB_MONI in PI, I see the acknowledgement given back to the IP, but in the SAP backend system I don't receive anything in the abap proxy which had send the original message. In de SXMB_MONI from SAP I see a "?" Still awaiting acknowledgement.
Can anyone help me with this scenario? I really need an acknowledgement from the file adapter in the calling abap proxy.
Regards, Jeroen

You need to crate a REceiver Agreement for this sender...
The Integration Server sends an acknowledgment message back to the sender (CENTRAL_BACK). It uses the name of the sender system for logical and technical backward routing.
If the sender is addressed using an ABAP proxy, you must define a corresponding receiver agreement for this sender.

BPM to get rid of polling for file adapter

Hello,
nice scenario here:
We want to trigger a scenario for file to file transfer via an aRFC to be independent from the polling.
Looks like this needs a BPM, which could be started via an aRFC (save e.g. the content of the RFC in a directory on the XI machine if necessary).
But how to trigger now the sender adapter to pick up the prepared file (no relation to the content coming with the RFC) to deliver it?
Looks like we do not really understand how to use the BPM? Any idea to solve that is welcome!
Best regards
Dirk

Hi Dirk,
take a look at this weblog by siva:
/people/siva.maranani/blog/2005/05/22/schedule-your-bpm
schedule your BPM and then you can use pooling
for the file adapter cause the message will stay in BPM
and you can control from the BPM

Acknowledgment not possible ..File adapter ..receiver side

Hi XI Friends
In my Simple IDOC to File Scenario...
i am getting successfull meessage in SXMB_MONI.but in sxmb_moni ,the acknowledgment status is not possible.
my inbound inteface is of file and asynchrounous type.
how can i get acknowledgment .
please guid me.
thanks and regards
Ram

Hi,
File adapter does not support Application Acknowledgements.
In your case, turn of the Acknowledgements, by adding the entry in the table IDXNOALE in XI for the Sender Port and idoc type. After this, the Acknowledgement column in MONI will be empty.

File Adapter - BPM

My Scenario is
Start BPM - Receive Huge File from System A - Transform Big File into 8 Smaller Files - Send All Files using FTP adapter to System B- Invoke Webservice on System B to Process all the files earlier sent - If Response Message is successful then Archive all 8 files to Different Folder on System B- End BPM
How do I issue Archival process from BPM ?. I'm so confused about how to achive archival after receving Success message from Webservice.
Any Ideas will be appreciated..

Hi,
Two options:
Option1::
My Situation is CaseB:
No changes being made to these files except Webservice takes data and process the data and do not change files.
Since there are no changes at all being made to the files in systemB folderA, you need not poll them again.
You can use the same files already present in the BPM.
Solution:
1. Receive file from system A
2. Transform file - 1 file to 8 files (message split)
3. Loop. The loop will be used to send the files one by one to the webservice.
Within the loop:
a. have a container to store a single file out of the 8 files/messages generated as a result of the transformation.
b. have a send step to send the file one at a time to systemB folder A.
c. have a send step to send the file one at a time to webservice.
c. have a switch step after the send step.
If the response is positive, send the file to systemB, else, do nothing.
In the receiver file adapter that you will be using to send files to folderB, use a script to delete file from folderA and move them to folderB
Option2:
Actually speaking, all you need to do is to put the files directly to folderB rather that first putting it into folderA and moving it to folderB of systemB.
Putting files into folder A is redundant because:
a. there are no changes being made to the files in folderA
b. they are anyway going to be deleted after the files are placed in folderB.
So, what is the use of placing the files in folderA?
In case, you agree with the above, you need to design the BPM, same as the steps in option1. The only difference is that, you would not have the step 3b.That is, you donot have the send step that sends the files to systemB folderA.
Hope this is clear.

Smitha.

File by File picking with Standard File Adapter with NFS Protocal !!

Hi Folks,
How to pick file by file with little gap in a file directory by Standard File Adapter. One interface, one communication channle.
Ex: XML_XXXXX_XXXX1.xml
      XML_XXXXX_XXXX2.xml
      XML_XXXXX_XXXX3.xml
First I need to pick one file XM_XXXXX_XXXX1.xml then wait for 2 minutes and pick another one in ascending order.
I have tried with Advance option "File size" and "Msec to wait before modification check" with 1200000 MS, but no use.
Please folks any one can help in this, which is very big help?
Kind Regards
Many Thanks in advance

Hi
My BPM steps are as follows:
1. Receive step -- Asynch
2. Transformation -- split the message
3. Switch step -- Condition "ID != ' ' from transform message'
4. In side Switch Branch 1 -- Receiver determination - Receive acknowledgment - Application
5. Send 1 -- with Application Transport, Queue Name - 'XXX'
      This XXX queue I have configured on ID with EOIO Service
6. block step - Send multiple messages to same receiver on top
    I have send 2 different message to one receiver, the first message is only one , second message are multiple. I am splitting    with transformation step
7. Sender -2 no acknowledgement active
8. stop
Can you please tell me where I am gonna wrong!!
I will apprecite for your efforts
Regards

Setting Delay in File Adapter

Hi All,
I have a file to ABAP proxy asynchronous scenario.
In the source directory i have 2 xml files. The second XML file should be picked up by the file adapter only after processing the First file by the ABAP proxy.
I know about setting delay in Mapping. But this wont suffice my requirement.
Appreciate your help in this
Keerthi

Hi,
do'nt thing so wait modification will work...
try it with the help of BPM
file is in Asyn Mode.
So 2 message will be there for 2 file, now it can be handled in BPM, that if proxy return OK acknowledgement for 1st message,
then 2 mapping should executed.
File1 -{BPM receive step -> transformation-> Sync Send -> if proxy respone ok , Block->then 2 transformation else leave the 2nd file message}.

Get additional file attachements with file adapter

Hello,
Has anyone ever had the following situation:
A Sender interface sends a little bit of data to XI.
This data contains the filenames of some files on a FTP server.
Based on these filename the file needs to be retreived from a FTP server and further handled as an attachement of the XI message?
Is it possible to trigger a sender file adapter with a variable directory and filename from XI, in a BPM or Mapping?
Warm Regards,
Leon Boeijen

hi,
>>>>Is it possible to trigger a sender file adapter with a variable directory and filename from XI, in a BPM or Mapping?
no it's not possible to start a file adapter from BPM
you can use a java proxy that will do the trick
we've used a solution like this many times with no big issues
remember that it's better to use an async java proxy
(with correlation) then a sync one...
