Thank you for your document, but my scenario is bit simple , when file appears in Directory without reading whole file just needs to trigger the event using FM BP_EVENT_RISE, how we can achieve this without reading massive file data
create Scenario like File to Proxy with dummy structure.
At Sender side use some dummy structure with occurrence one and define the dummy FCC parameter which read just first line of the file and create a message and in mapping you can ignore that data and send some dummy or constant value to proxy which will trigger your event in proxy code "BP_EVENT_RISE"
You can use two directories in the BI system, “Received” and “Treated” . PI can poll the received directory, if PI find a file, it will archive the file directly in the sender file side. The scenario will be FILE – RFC, you don need to pass any value, no problem you only trigger the RFC.
I just check that BP_EVENT_RISE is not a RFC, you will need to wrap it with a Z RFC function.
RFC will trigger when you have get the file from “Received” directory and your sender File communication channel with archieve the file in “Treated” directory (in source server).
Just create a file to XI Proxy scenario. The receiver adapter will be XI in this case.
In the proxy code call the FM BP_EVENT_RAISE to raise an event.
In this case you have to use file content conversion to do some mapping as i guess you are using flat file.If the file is already XML then just do a simple mapping with source and target structures the same.
2nd option :
if your file directory is accessible through your BI system(if the directory is mounted) then you can create a simple program to run as a batch job in BI system which wll check if the file is there in the directory and if its there an event will be raised.
3rd option :
Create a simple file to file scenario without ESR in PI and transfer the file to a directory oin BI system and then create a program as per option 2.
Sorry for the delay in the response, but this is not working, I am getting the below Error in RWB:
Explanation
Error 21/01/14 12:04:23 Conversion initialization failed: java.lang.Exception: java.lang.Exception: java.lang.Exception: Error(s) in XML conversion parameters found: Parameter 'RecordSet.fieldFixedLengths' or 'RecordSet.fieldSeparator' is missing Consistency check: no. of arguments in 'RecordSet.fieldFixedLength' does not match 'RecordSet.fieldNames' (0 <> 1)
you can read the file name from sender File adapter (by checking the ASMA option File name). The you have two option
Set the file name to one of the field in message (proxy can read the field and store in table)
Set the dynamic variable at header
First option is straight forward and easy to implement. for the second option you need to consume the soap header in ABAP proxy code. Please refer the below thread for consuming soap header
