Hi,

We can connect to R/3 to create, retrieve, udpate & delete data from WebDynpro using Adaptive RFC model.

While creating the Adaptive RFC model we need to specify the model data & metadata JCO destinations.

SSO:

SSO is to access multiple applications with single login. You need to configure to access the applications running in different severs in the same portal.

JCO Destiations:

You need to configure these destinations to connect to SAP R/3 backend system from WebDynpro using Adaptive RFC model.

There are two types of JCO destinations:

1. Metadata destination:

This is to get the latest meta data of the backend RFC. This is not for sending/receiving the user speicific data. So here SSO is not required. You can use userid/password mapping logon sso method.

2. Modeldata destination: This is to get the process data (user specific) during the RFC execution from WebDynpro. So here you need to configure the SSO as it is user specific application data.

Go through the below document for step by step process with screen shots:

Function module to get the message server host name and port in R/3.

Hi viswa,

I think you need to have an SLD entry in JEE server. Go to http://<host>:<port>/sld

[Configure SLD to connect to ABAP System|http://help.sap.com/saphelp_nwce711/helpdata/en/48/b681d296655295e10000000a42189b/content.htm]

then you can continue with Srikanth's points

You have to configure your SLD and create JCO connections.

Hi ,

To create JCO ,

In content adminstration->webdynpro> u will find create JCO destinations tab.

Here u have create JCO for Model data and Dictionary Data(Metadata).After creating JCOs u can test them there it self.

Go through the link,describes how to create JCO

http://help.sap.com/saphelp_nw04/helpdata/EN/3a/3b1b40fcdd8f5ce10000000a155106/content.htm

In webdynpro to connect to r/3 u have to create Model by giving these JCO destinations.

Refer the link,describes how to use bapi in webdynpro using Adaptive RFC model

For communicating with R3 through RFC enabled function modules from your NWDS, you have to create a model (by giving your SAP R3 user id and password) import the RFC enabled function modules and then use them for development in NWDS.

What is your exact requirement?
