PI 7.1: WS RM Adapter to IDOC SAP Integration

Hi All,
I had a few questions on WSRM-IDOC integration in PI 7.1. This is mainly related to understanding of WS-RM Adapter integration.
Please provide your thoughts and inputs to the following questions:
(a) I am under the impression that WS -RM adapter used for Web services cannot be used in asynchronous scenarios. Am I correct?
(b) If WS-RM Adapter can be used for asynchronous scenarios, how do we do it?
(c) Since I assume that WSRM Adapter cannot be used for asynchronous scenarios, if I use the scenario WSRM - IDOC (asynchronous) adapter, then I have to use BPM (Sync-Async communication). Am I correct to believe that WSRM -IDOC integration is not possible without BPM?
(d) In case WSRM-IDOC integration is ONLY possible with BPM, is WS-RM --- ABAP Proxy better than WS-RM -- IDOC integration?
Thanks in advance.
Thanks,
Manohar Dubbaka.

(a) I am under the impression that WS -RM adapter used for Web services cannot be used in asynchronous scenarios. Am I correct?
Actually WS adapter only supports Asynchronous communication (EO/ EOIO)
(b) If WS-RM Adapter can be used for asynchronous scenarios, how do we do it?
The corresponding Service Interface (in your case sender) should be having mode as Asynchronous
(c) Since I assume that WSRM Adapter cannot be used for asynchronous scenarios, if I use the scenario WSRM - IDOC
(asynchronous) adapter, then I have to use BPM (Sync-Async communication). Am I correct to believe that WSRM -IDOC
integration is not possible without BPM?
(d) In case WSRM-IDOC integration is ONLY possible with BPM, is WS-RM --- ABAP Proxy better than WS-RM -- IDOC integration?
NA
Update:
To confirm what I said refer the QoS column for WS adapter in the table over here:

                   (ex.ineed to config comm. channel for both)
     Can anybody help me out?
Thanks

Sender QoS is BE,
File adapter does not support sync communication. Therefore the scenario won't work as it is.
What are you planning to do with the response? If you want to process is further, then:
1. One way without BPM would be use of adapter module.
File - RFC - File without a BPM - Possible from SP 19.
2. Or you may use BPM with Async Sync bridge

SM58 - IDoc adapter inbound: IDoc data record table contains no entries

Trying to send Idocs from SAP ECC6.0 via PI 7.0 up until 2 days ago there was no problem.
Since yesterday, only one specific type of Idoc does not make it into XI (PI). In the Idoc monitor (WE02) the idocs that were created gives status 3 which is good. But all Idocs of that specific type (ZRESCR01) does not go to XI. I can only find them bakc in SM58 where it gives the following message:
IDoc adapter inbound: IDoc data record table contains no entries
I have checked SAP notes 1157385 and also 940313, none of them gives me any more insight into this error. I have also checked all the configuration in WE20, SM59, and in XI (repository and directory) and in XI IDX1, IDX2 but could not find anything that would cause this. I can also not think of anything that changed since 2 days ago.
Please point me in the right direction.

hi,
i think in sm 58 u can find entries only when there is some failure in login credential .
if there is change in IDoc structure than you have to reimport the idoc metadata defination at IDX2.otherwise not requird.
please check the logical system name pointing to the your requird target system....
please also verify thet your port should not be blocked.
pls find the link it may help

IDoc flat file over AS2 adapter to IDoc adapter

Hi,
The scenario is IDoc flat file(.txt) over AS2 adapter to IDoc adapter. Could anyone help on how to convert the IDoc flat file to xml in AS2 adapter to execute the mapping further? we are using PI 7.0.
Thanks in advance!
-zameer

Hi,
Since you are on Pi 7.0, you would not be able to use the modules for this in PI 7.1.
You would need to refer this document for converting from Idoc flat to XML
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/46759682-0401-0010-1791-bd1972bc0b8a?quicklink=index&overridelayout=true
In your sender AS2 adapter, you can pass the file as is to an abap mapping which will do the conversion to Idoc xml. the output of the abap mapping goes to your message mapping then for conversion.
Another option would be to use a custom adapter module in the sender AS2 adapter to call the Aabap mapping to do the conversion into Idoc xml.
The custom adapter module would do a JCO/RFC call which will do the conversion before passing the data back to the adpter module.

IDoc adapter with Non SAP systems

SAP XI 3.0 help says:
You can use the IDoc adapter to connect SAP systems (as of release 3.1) and non-SAP systems with the Integration Server using native IDoc structures
What does this mean?
-Naveen.

Hi Naveen,
Let me give a use-case in one of our projects ....we have 2 middlewares in our landscape...webmethods and XI...and in one particular instance there was a need to send an FI IDoc from webmethods to XI and forward it to R/3....
In this case, the webmethods was treated like any other sap system for receiving IDoc into XI(with settings in IDX1)...
Hope this might clarify a little bit...
Thanks,
Renjith

IDoc adapter inbox: IDoc sender partner is initial

Hi,
I have requirement to read the IDOC flat file and post IDOCs to SAP. As suggested in the following guide I am using report RSEINB00 to post IDOCS. This report basically calls the function module IDOC_INBOUND_FROM_FILE.
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/xi/xi-how-to-guides/how%20to%20convert%20between%20idoc%20and%20xml%20in%20xi%203.0.pdf
While executing the IDOC_INBOUND_FROM_FILE I am getting error:
"IDoc adapter inbox: IDoc sender partner is initial".
Please advise.
Thanks
Rajeev Gupta

Hi,
Idoc will be processed in SAP ECC based on the sender details (snprn,sndpor,sndpfc...) of idoc control record..
instead of different partners name sending in the sender details of control record ...pass the value of the PI logical system name in SNDPRN.... (use only one and this is common for all partners...) any how data records of idoc will have the needed partner details...
In SAP ECC you need to have this logical system ...to process the received idocs..
thats it... Hope you got

Why we use IDOC adapter for IDOC as reciever?

hello,
Why we use IDOC adapter while using IDOC as receiver, whereas we don't use IDOC adapter while IDOC is sender?
I am clear about why we don't use adapter for sender IDOCs.
Thank you.
Sarika

Hi Sarika,
>>>>Why we use IDOC adapter while using IDOC as receiver,
maybe the easiest answer would be that we use
IDOC adapter as receiver to tell the XI where he should
send the data - there are many systems to which we can
connect our XI and somewhere there has to be an object
which will tell thx XI "where to" -> which RFC destination should it use
BTW
I believe IDOC apdater is also used as sender
although you don't configure it in AF:
"Once the IDoc has left the application through the RFC interface and has reached the <b>IDoc adapter</b> at the Integration Server inbound channel, the system converts it from IDoc format to IDoc XML format"

Reg Adapter Module in SAP PI 7.11

Hi,
I am trying to develop an Adapter Module using SAP NWDS and I am referring http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/c0b39e65-981e-2b10-1c9c-fc3f8e6747fa?quicklink=index&overridelayout=true for the same.
Now I am stuck on page 11 (page 16 of the pdf).
Does the value of Remote interface have to be strictly com.sap.aii.af.lib.mp.module.ModuleRemote (similarly for other parameters)?
Are these values dependent on the Default EJB Package that we use (mentioned on page10). Because the name of my package is com.companyname.adaptermodule and is as per the naming convention that we follow.
Thank you,
Pankaj.

Hi,
Ok. Actually I thought that the names are dependent on the default EJB package-name that we specify in previous step; but now these two do not seem to be related to each other (name-wise)
The question seems to be answered for now. Thanks to Stefan.
Thank you,
Pankaj.

Call rfc sender adapter from non-sap systems

Hi,
is ist possible to connect to an rfc sender adapter from non-sap systems? I want to use the the RFC-Connector from http://rfcconnector.com, but in the client connect options there is no way to specify the program id.
Best regards,
Daniel

hi,
you don't need to use RFC type T (with program ID) - you can use whole connection string - just like in the example:
http://www.rfcconnector.com/documentation/examples/client/#functioncall
so just specify: host system number etc.
it should work like that - but let me know as I don't know this RFC connector

Error: Idoc name IDoc cannot find request IDoc in Integration Server

Hi,
I am getting an error while working on a scenario.
scenario is Idoc to file. when the Idoc is posted, i am getting the error "ALEAUDIT IDoc cannot find request IDoc in Integration Server" when i see the status in SXMB_MONI
I have tested the message mapping and configuration induvidually. They are working fine.
Kindly help me out in solving this issue.
please reply

Hi,
The AleAduit sent in the case of Idoc to File if the file is posted successfuly is not actually a App Ack, and that is why we get the info Ack not possible.
But, as the R3 might expect this Idoc, XI still sends it back to the Source R3 system.

ALEAUDIT IDoc cannot find request IDoc in Integration Server

Hi,
i m working with a scenario SAP ECC 7.0 -> IDoc -> PI -> IDoc -> R/3 4.6c
I m sending a purchase order (ORDERS.ORDERS05) from SAP ECC and i want to receive an acknowledgment from R/3. Unfortunately there are only zeros in the field E1ADHDR / E1STATE / DOCNUM, this leads to the error "ALEAUDIT IDoc cannot find request IDoc in Integration Server" on PI.
Does anybody know what to do in the R/3 system to send the original IDoc number in E1STATE / DOCNUM?

Hi Volker,
yes, that was the right hint
I needed to change the RCVPRT field to LS to force the receiving system to send the ALEAUD with original number at the right place. Strange reaction, but it is SAP software, he, he.
