RFC .Net Connector with BAPI_DOCUMENT_CREATE2 (DMS)

Former Member — Wed, 26 Nov 2014 16:47:48 GMT

Hi, I have the following Problem:

I want the upload some Files to SAP dms System.

First of all i implement the functionmodule "BAPI_DOCUMENT_CREATE2" in my .net Programm.

Then i tested tue Applikation... and the RFC call creates an correct document Info set in erp. I can have a look on it, with CV03N.

Now i wanted to implement the fileupload.

So i filled the Table DOCUMENTFILES ANd copied the sapftp.exe in my Program Exekution Directory.

If i now call my .net Program, it crashes with the exception "callback not supported".

What is my Problem?

I cant Figure it out.... Thanks for the help.

My Code:

...if i use the Parameter:

parms.Add(RfcConfigParameters.UseSAPGui, "1")

in BackendConfiguration Class; the upload will work.

But in productive Environment there is not SAP GUI installed.

So i find out, in sap 504692 (https://websmp230.sap-ag.de/sap(bD1kZSZjPTAwMQ==)/bc/bsp/sno/ui_entry/entry.htm?param=69765F6D6F64653D3030312669765F7361…) that i have to use functionmodule "CVAPI_DOC_CHANGE"...

Now i can switch parms.Add(RfcConfigParameters.UseSAPGui, "1") to parms.Add(RfcConfigParameters.UseSAPGui, "0"), so no SAP GUI is used.

But i get an error: "Error while checking in or laydown of XXX (my documents path)" or something similar.

There is no practical way.. i will build my own functionmodule with xstring...
