JCO Error when communicate with a UNICODE ECC6.0

48 Views

HI all,

we use JCO to get data from SAP R3 system.

Before, our R3 is non-unicode system and it work OK, now we want to upgrade to ECC6.0 and its a UNICODE system.

when we send data from ECC6.0 to the JCO Server, the conncetion is OK, but we get no data from SAP ECC6.0.

i find some documents about the solution of UNICODE backend sysytem, and i followed them:

1- set the 'UNICODE' option of my destination in SM59 ;

2- set the UNICODE property of my JCO Server: this.setProperty("jco.server.unicode", "1");

after this, it can still not work.

ist, i test the destination, its not OK

then i send data to the JCO Server, i got an error:

com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: See RFC trace file or SAP system log for more details

pls help.

thanks a lot
