problem with export for system copy

hi

i am using  SWPM for a system copy but it came out with error on the export phase on the source server

aix on oracle

Unloading of 'APQD' export package is interrupted with R3load error.

Process '/usr/sap/FTP/DVEBMGS00/exe/R3load -e APQD.cmd -datacodepage 4103 -l APQD.log -stop_on_error' exited with return code 2.

For mode details see 'APQD.log' file.

sapparam(1c): No Profile used.

sapparam: SAPSYSTEMNAME neither in Profile nor in Commandline
