I woukd like to know about the returncode and its uses, its fuction ,how this works
thanks in advance
There are several 'returncode', you to transfer/update routine.
in transfer/update routine, it can be used to skip record. if the returncode is not equal zero, the result will not be updated
other return code can be found in transport process e.g, returncode 0 means successful, 4 means warning, 8 or 12 means error.
basically it's can be code returned by process in abap e.g (normally get with system parameter sy-subrc).
hope this helps.
