problems with RFCGetFunctionDesc in NW RFC SDK

[Former Member]

Hi, All

I met a problem with NW RFC SDK 7.11 when using RFCGetFunctionDesc to access a ABAP which is defined by myself. I used to access this function with RFC classic SDK successfully, however, when i use NW RFC SDK and use RFCGetFunctionDesc to access this ABAP function, it returns the "RFC_INVALID_PARAMETER" and with error message "inconsistence in description detected: non-unicode length is too small". And My application can retrieve the function Description handle of other ABAP functions, I'm wondering if it's a bug in NW RFC SDK

I search the network and found someone has the same problem:https://weblogs.sdn.sap.com/cs/user/view/cs_msg/28225

Could someone share some tips to diagnose this problem.

Best Regards

Having the same problem with the latest NW RFC SDK 7.20 and a Basis 620 server (SAPKB62060).

The release notes for NW RFC SDK 7.11 patch 1 and 2 say this was fixed, but apparently it wasn't, or at least not for all server versions.

I'm wondering how to get around this.

Hi Sergej,

                We are also getting the same error for Basis release 640 ( Unicode ) and SAPNwRFC720 release from BODS. Are you able to resolve the problem ?

Thanks,

Hi,

It seems you need to install current patch level (NWRFC_1-2000xxxx.SAR) of the SAP NW RFC SDK, as described in Note 1025361.

Please check Note 1236530 - SAP NW RFC SDK 7.11 -- Patch level 1

Thank you,

hi, thanks for you reply.

Actually what I installed is NWRFC_1-20004550.SAR, which I believe is the latest NW RFC SDK. And also my error is not identical to the one described in the release notes of SAP NW RFC SDK 7.11 -- Patch level 1

Here is more info about what I tried:

My BAPI function is simple, no import/export/change , but only a table parameter.

I use the DDIF_FIELDINFO_GET function to check this table , and found the structure length of this type is equal to the sum of offset and intlen of last field.

My system info : SAP_BASIS release 640, SAP_BW release 350.

So do you have any other suggestions.

Best Regards
