RFC_ERROR_SYSTEM_FAILURE with SAP ECC 6 Unicode

Former Member — Tue, 12 Oct 2010 13:13:39 GMT

Hi All,

I am using BizTalk 2006 R2, Microsoft BizTalk Adapter v2.0 for mySAP Business Suite SP1 & SQL Server 2005 as a Database server.

In past we developed Orchestrations which were communicating with SAP version 4.7. Currently SAP has been upgraded in ECC 6(Unicode) system.

I have configured new Send Port on server. Orchestration was able to communicate with SAP ECC 6.0 (Non- Unicode) system but while trying to connect with SAP ECC 6.0 (Unicode) I am getting error.

A message sent to adapter "SAP" on send port "ECC 6 SendPort" with URI "sap://AS:**..*.*//**/" is suspended.

Error details: RFC_ERROR_SYSTEM_FAILURE

I also installed RFC SDK 7.10 Unicode version an also set environment variables for SAP GUI tracing. Now I can execute RFC which returns CHAR value but in case of NUM data type, I am getting following error in trace file,

T:4012 Error in program 'BTSNTSvc':

>> ERROR: Import parameter length difference detected.

Read length: 7. Expected length: 0. Type: 2.

T:4012 Error in program 'BTSNTSvc': <* RfcReceive [2] : returns 19:RFC_INVALID_PARAMETER

T:4012 Error in program 'BTSNTSvc': <* RfcCallReceive [2] : returns 19:RFC_INVALID_PARAMETER

T:4012 Error in program 'BTSNTSvc': <* RfcCleanupContext [2] : returns 18:RFC_INVALID_HANDLE

Thanks in advance.

Hi Pankaj,

please note that there are metadata length differences between non-Unicode and Unicode systems.

This has to be taken into account if you have hardcoded the length in the used connector.

Please also have a look at the RFCSDK Guide:

Hi Nils Buerckel ,

Thanks for your reply.

I have installed & registered the lib32.dll & lib32u.dll files. Also I have checked the settings on biztalk server.

Still I am not able to use the custom RFC having num or currency data type. Rest of custom RFCs works fine.

Please help me on this .

Hi Pankaj,

you stated that you 'developed Orchestrations' - how did you realize this functionality ? Do you use C or C++ ?

Hi Nils Buerckel ,

We have developed Orchestrations on Biztalk server using C# .

Hi Pankaj,

please have a look at:

It seems that for some objects there are restrictions in Unicode systems.

Best regards,

Nils

Nils Buerckel ,

My problem is solved.

I have removed all export parameters from my custom RFC and instead of that used tables to return data from RFC .

Your last answer was really helpful.

Thanks for your help.
