Synch RFC

[Former Member]

Hello,

I am doing an interface - R3-XI-File. The R3 RFC is called synchronously. I am checking if the file is posted at the receiver side or not by using Transport ackin BPM. In exception handling, deadline handling - I am returning the response to R3.

These are the steps I did,

1. I have rfc dest of type TCP/IP - in R3 - used that program id and defined RFC sender adapter in XI. - checked if rfc dest works - works fine. I have used the same rfc desc for Asynch process which works fine.

2. I have called the RFC inside a fm like this

call function 'ZFM_RFC_SYNCH'

destination 'XIRFC'

tables

FT_table1 = ITWA_table1

FT_BAPIRET2 = FT_BAPIRET2.

3. I am getting the following error in the sxmb_moni

SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

<SAP:Category>XIAdapter</SAP:Category>

<SAP:Stack>This process does not support the specified synchronous interface or does not support any synchronous messages The exception occurred (program: SAPMHTTP, include , line: 0)</SAP:Stack>

<SAP:Retry>N</SAP:Retry>

</SAP:Error>

4. Audit log shows me this

Success RFC adapter received sRFC for 'ZFM_RFC_SYNCH' from R3/010. Attempting to send message synchronously

Success - Application attempting to send an XI message synchronously using connection AFW.

Success - Trying to put the message into the call queue.

Error - Transmitting the message using connection http://host:port/sap/xi/engine?type=entry failed, due to: XIAdapter:SYNCHONOUS_MESSAGE:.

Error - The message status set to FAIL.

Anyone knows where the problem is exactly???

My BPM has receive step - opens SA bridge - then mapping to file message type - block with send step to file adapter - which has deadline and exception handling - for transport ack - and then send step to RFC resp - close SA bridge...

Anyhelp is greatly appreciated.

Thanks

HI,

CHeck the RFC response structure ? Also make refer this blog once-

I think the problem is in Abstract Interfaces used in the BPM etc

Krishna,

Thanks for the reply.. My scenario is sync-async...I have to send the response back to R3 based on whether the file has been posted on the receiver side or not...

For this I used file ack .

1. step 1 - receive step - open S/A Bridge - sync rfc interface of R3

2. Inside block - a. transform step - for rfc req to File format. b. send step - asynchronous - has transport acknowledgement - for file. This block has deadline of 1 min and it throws exception if 1 min is reached. In the exception branch, I have transformation step - which is like a dummy mapping - same file format to rfc response. in which I am setting the type and message of the bapiret in rfc. So I inactivated the file adapter - which should make the bpm run for morethan sometime - after a min, calls deadline branch - which throws exception - sends response to R3. The objective is if the file was not posted in the receiver side - the sender - R3 should know abt it.

3. send - closes s/a bridge - uses rfc resp message to send back to R3.

questions:

1. Do I have to have a sync receiver(instead of file) inorder to send resp back to R3? as I am doing a dummy mapping here in exception branch, would this cause a problem????

2. I am checking if the BPM is active more than a min - in deadline - instead of that - is there any other way to know if we got +ve or -ve ack from file adapter and map that to a message.

3. Do we set up R3 as a receiver to receive response back from XI? in cofig?? (I dont think so - but I forgot)..

Thank you and appreciate your time...

After executing your scenario, is BPM is triggered ?

If so go to SXMB_MONI->PE->Technical details /Workflow log. SO that we can see the errors. I think, you are getting a Error in the Tranformation step of RFC response.

Even I am thinking in question no 1. I don't think so , it is possible. Because for a file system you are not sending the message with Sycnhronous Option right ? So I have a doubt here.

<i>3. Do we set up R3 as a receiver to receive response back from XI? in cofig?? (I dont think so - but I forgot)..</i>

>>Not required. For a Synchronous scenario it is not required to have separate Recieever Determination is requored for Response .

Alternative is you can try with Receiver Java Proxy (Java Server Porxy) which can act as a Synchronous. and even you can avoid BPM.

Hope this helps,

I found what I missed. The BPM had a wrong interface in Config side. Previously I had async scenario and changed to sync..so didnt change to sync interface....Now its working.

I have one more question...For File transport ack - can we check the particular return message and do the processing?? instead of deadline and exception branches??

If the transport is successful, I see this message

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<!-- Response

-->

<SAP:Manifest xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:wsu="http://www.docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="wsuid-manifest-5CABE13F5C59AB7FE10000000A1551F7

If its negative, I get

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<!-- Response

-->

- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

<SAP:Category>XIAdapterFramework</SAP:Category>

<SAP:Code area="MESSAGE">GENERAL</SAP:Code>

<SAP:P1 />

<SAP:P2 />

<SAP:P3 />

<SAP:P4 />

<SAP:AdditionalText>com.sap.aii.af.ra.ms.api.MessagingException: Channel 'File_Receiver', Service 'File', Party '': File Adapter configuration not activated: com.sap.aii.af.ra.ms.api.RecoverableException: Channel 'File_Receiver', Service 'File', Party '': File Adapter configuration not activated</SAP:AdditionalText>

<SAP:ApplicationFaultMessage namespace="" />

<SAP:Stack />

<SAP:Retry>M</SAP:Retry>

</SAP:Error>

the reason is, for negative ack I use the exception brach and send the resp to R3 - saying the file was not processed. But if its success..I shold have another dummy mapping which should say successful....which I am not very much happy to do...is there any other way you can think of?? or worked on???

Thank you for all your great suggestions...

Krishna,

Do you have any documentation to use Java proxy to use in the receiver side? Do we bypass receiver file/ftp adapter??? Could you please provide some additional documentation?

Thank you

Hi,

If you use Java Proxy, no need of File Adapter.
