sapnwrfc call to non-unicode system

[former_member484270]

Hi,

We are using the beloved Ruby gem to connect to SAP via linux environment. The website of course is utf-8 and the SAP codepage is 1100. The SAP gui codepage shows at 1160.

As per this wiki article https://wiki.scn.sap.com/wiki/display/ABAP/Character+encoding+conversion

We set our codepage in the rfc interface to match at 1100 or 1160 and we set the rfc.parameters encoding to WINDOWS_1252 or else ISO_8859_1

When we call RFC_PING, we see the following:

{"dest"=>"", "host"=>"dev.internal", "partnerHost"=>"(suppressed)", "sysNumber"=>"00", "sysId"=>"CEQ", "client"=>"010", "user"=>"(suppressed)", "language"=>"E", "trace"=>"0", "isoLanguage"=>"EN", "codepage"=>"4103", "partnerCodepage"=>"1100", "rfcRole"=>"C", "type"=>"E", "rel"=>"720", "partnerType"=>"3", "partnerRel"=>"731 ", "kernelRel"=>"721 ", "cpicConvId"=>"42534404", "progName"=>"SAPLSYST"}

If I understand correctly, sapnwrfc library expects codepage 4103 which is unicode, but our target SAP system is NOT unicode.

Can anyone explain where/how we alter the RFC processing to safely convert a user's entry to something that we can pass into SAP?

Dear Ray,

if you go to SM59 and choose the RFC destination, which checkbox is chosen in the UNICODE tab?

How is the line of communication set up?
CEQ (Non-Unicode) < RFC destination > Unicode Frontend?

Codepage 1100 is the backend codepage. Frontend Codepage 1160 is for Windows. If you have a linux environement it should be 1100 as well. Please check https://wiki.scn.sap.com/wiki/x/Oxx7H for more information on this.


Cheers,
Andreas
