I've read sdn and sap notes and didn't find a solution.
My problem is that i'm sending a 14mb file via ASYNC RFC. The message is going well from XI to R3, but when i have to get the response from the XI via another RFC, i check in SM58 this message : java.lang.OutOfMemoryError
I have changed in exchangeProfile parameter maxheapsize to 1534m and it doesn't work.
any other solution?
