Request return code has differnt return code.

     Hi experts.

     I sent request from DEV system to PRD system at OS level but I am facing interesting problem. I sent request at OS level and return code 8, that means with error but if we look same request transporter log  at SAP side vi tranzaction SE01, Transporter log show me no error. I did not test with return code 0(zero), 4 or 12 at OS level.

Our OS  is SOLARIS 11.2 and Database Oracle 11G and SAP Netweaver 7.40.

Thank for help.
