DYNAMIC RECEIVER

Question

Hi,
I have file (from FTP) to multiple idoc scenario, where in a file with PO details comes and i create one idoc per PO. the structure is as follows
<BATCH>-1
<POHEADER>-0-UNBOUNDED
-<POITEM>-0-UNBOUNDED
Now my requirement is that i need to do 3 validations
1) Batch has a field STATUS if this is 'P' then send error message saying "batch is processed" back to FTP server.
2) If the ORDERCOUNT feild of batch has different number  as occurance of  POHEADER then send message "order count doesnt match".
3)If the ITEMCOUNT feild of batch has different number  as occurance of  POITEM then send message "item count doesnt match".
Now can anyone tell me how do i achieve this without BPM, is it possible via extended receiver determination, because i need separate error message text(thought the error data type remains same ) for all the three validation

Answer 1

Yes ,
Certainly , You can do this without BPM.
There may be few other ways also , i am explaining you one out of them .
Message Mapping . Create three message Mapping .
i. ) File sender to IDOC Receiver
ii.) file sender to file receiver (with error information).
iii.)file sender to receivers ( Message type :Receivers namespace : http://sap.com/xi/XI/System) : This one will be used to choose receiver dynamicaly.
at target Message type :Receivers the element Service Populate with the value of buisness system based on your condition.
like in your case : IDoc receiver Buisness system if counts matches, else File Receiver buisness system if count doesnt matches.
Operation Mapping . Create three Operation Mapping .
i. ) File sender OUTB to IDOC Receiver INB
ii.) file sender OUTB to file receiver (with error information) INB.
iii.)file sender OUTB to ReceiverDetermination INB
( target service interface :ReceiverDetermination namespace : http://sap.com/xi/XI/System) : This one will be used to choose receiver dynamicaly.
Rest is same in ESR Side.
Now let us come to Key points in ID.
1. Receiver Determination.
It would be extended : Here choose third Type Operation mapping : iii.)file sender OUTB to ReceiverDetermination INB
this will deside, Receiver Dynamically.
2. Interface Determination.
now for each buisness system , create interface determination and choose appropriate operation mapping.
Rest steps would be same ....
Do ask if found any problem .
