File to RFC synchronous scenario stopped Picking the files

[Bhargavakrishna]

Hi Experts,

We have a File to RFC synchronous scenario. Till yesterday night it is working fine.

But suddenly it is stooped working.In moni, i can see the failed messages with the Mapping error " Can not create target element, values missing in the queue context "

No Payload in moni / communication channel monitoring / Message monitoring. I've noticed that, wrong files placed in the To-be- processed files and the adapter picked those files and failed in mapping.

I tried by stop and start the communication channel / did some dummy changes in the communication channel and activated. cleared the cache.

But still the communication channel is not working.when i stop and start the communication channel it will try to process the wrong files and failed.

Give me your valuable inputs to resolve this issue.

Regards

Hi Bhargava,

Sorry, i missunderstood the problem. What is your PI version and patch level?

Check this Note 1483974 - File and JDBC sender adapter's retry not working after error

You can increase the ftp timeout, sometimes this exception blocks the channel: Note 1687688 - FTP sender channel stops polling

Also, like workaround, you can copy the communication channel and create a new one, link it with the sender agremment.

Hi Bharghav,

Please go through the below,

Symptom

FTP Adapter is being used in the business scenario for message processing.

During file processing it is noticed, that the FTP sender channel stops

polling. There is no error in the channel monitor or the trace/log files

and the polling jobs are correctly displayed in the AFW scheduler table.

The issue is observed after a network connection issue with the FTP server.

In order to remove the hanging locks from the FTP Adapter, the parameter

'ftp.timeout' setting is required to be set, which releases the lock once

the timeout value is expired. But in the above situation, the value for the

'ftp.timeout' is not taken properly while establishing the data connection

by File Adapter.

Other terms

FTP Adapter, sender, FTP, adapter, timeout, stalled, network, hang, polling

Reason and Prerequisites

Program error

Solution

The hanging situation has now been improved by code changes. Please see

section "SP Patch Level" of this note for a list of updated software

components.

To get this correction available in your Support Package you need to apply

the patch matching to your Support Package version as per the instructions

in the NetWeaver Support Package Stack guide which can be found on the SAP

Service Marketplace as described in SAP Note 952402.

Thanks & Regards

Hi Bhargava,

This is a problem with the file content conversion, may be the file structure has changed, try to compare the files with the old ones that were proccesed.

Hi,

Yes there is a problem with the file structure. wrong files placed in the FTP folder and the adapter is Picking those files and showing an error.

My question is why it is stopped picking the other files..

thanks for your reply...
