Unable to convert the sender service PPG to an ALE logical system

[Former Member]

Hello all,

maybe anybody can help or give me further information.

I have set up a scenario to send IDOC from a business system ( ERP ) to a business service ( EXT ).

Receiver is a linux system so I use the FTP-FILE adapter as communication channel.

The send-process is so far ok.

Here my tests:

1) exclude the specific IDOC in IDXNOALE table ( means no technical acknowledgment for this IDOC )

result :

a) message in SXMB_MONI: status-flag: processed, acknowledgment-flag: not in use

b) message in RWB-Monitor: Sender ERP --> Receiver EXT ok

2) But I would like to have a system status..... here now the problem

add specific IDOC into IDXNOALE table ( for request acknowledgments )

result:

a) message in SXMB_MONI: status-flag: processed, acknowledgment-flag: acknowledgment not possible

--> error message: unable to convert the sender service EXT to an ALE logical system

b) message in RWB-Monitor: there are now two message,

first: Sender ERP --> Receiver EXT = ok

second: Sender EXT ---> Receiver ERP = system error

Receiver-Interface is : http/ww.ahlstrom.com/EXT/ MI_IN

3) furhter tests:

a) change FTP apdapter channel ( put some wrong settings )

message in SXMB_MONI: status-flag: processed, acknowledgment-flag: contains system errors

message in RWB-Monitor 3 messages ( one ok, and two error messages )

b) changed only the receiver communication channel to HTTP ( other extisting scenario )

then the acknowledgment works fine wihout errors.

I'm wondering, but here Receiver-Interface is: http://sap.com/xi/xI/Message/30/Acknowledgment

Summary: The process works, but strange:

message in SXMB_MONI: unable to convert the sender service EXT to an ALE logical system

message in RWB: system error

No problems with HTTP adapter

Have just added " logical system " for the IDOC adatper in the " adapter specific identifier ".

Now I have have the same behavior but without erros in the monitoring.

Many thanks.

Hi,

Addition to the above said by Udo...

for routing the ack back to the sender system you need to create communication channel of type idoc with name as Ack.....

Hi,

Check this [http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/1439] [original link is broken] [original link is broken] [original link is broken];, are you using parties ? in your target system what is the partner name that you want to use ?

if you define something like LS_PPG it should work

Hi Reinhard,

just add a "adapter specific identifier" to your BC. Otherwise the returned Acknowledgment has no value for "logical sytem name". Setup a partner profile for ALEAUD inbound.

Udo
