big File to IDOC - performance issue

102 Views

Hi All,

I am trying to create scenario where I have a file with aproximately 10 000 rows. From each row I am creating one IDOC and want to send it to R/3. Interface looks fine - it is working, but it is killing XI box for some time and u cant access it.

Full scenario look like this

File -> BPM (for 1:n) -> IDOC

I tried to find some solutions for doing the workload smaller by splitting file to less lines (500rows per file) but then file adapter picks up all file and processed them in parallel. So this is new scenario:

BigFile -> XI -> File -> BPM(1:n) -> IDOC

I tried to put second file sender communication channel as EOIO but looks like this does not work - or messages from queue are processed to fast. When one message starts BPM another file message start to be processed.

Do You have any ideas on how to make it more responsive and less performance impact?

thanks in advance.
