Iam using Customize RFC.I given export parameter, but it has no values for Import parameter. This SY-SUBRC = 4.but I dont know why it has no Import parameter; it may be NODATA, COMM (No communication between two system) and SYS (system failure).what is SY-SUBRC if RFC fails due to NODATA, COMM and SYS?
How can I find NODATA etc with sy-subrc?
I capture exception as follows.
NODATA = 1
COMM = 2
SYS = 3
OTHERS = 4.
Pls help me, To be reward all helpful answers.
