require information about Adaptive RFC model

[Former Member]

hi

i am developing an webdynpro application which uses Adaptive RFC model.

My application uses the rfc's which are residing in SAP R/3.

i needed some information

1) what authorization do we need to give to the SAP R/3 user so that the user can call,execute the RFC's in the backend.

2) since ill be calling the RFC's in the backend via the webdynpro application,will i need to take care of some special security or authorization issue for the backend user,if so then what are those issues which i need to take care of.

Thanks & Regards

Hi,

Once you created your function module in R/3 make it enable as remote.

And later make to give some role that role assign to your function group where your are function module is define.

Goto PFCG transaction and add your role to your RFC and you can access.

click authrization default button and add your function module.

thanks,

Lohi.

hi

You donot need any kind of special authorization,whenever you create a jco detsination mention the user and password of the r/3 user.

If you are using ticket then your application data jco destination should be of type ticket and metamodel destination as user & password.your r/3 should be in the landscape of portal

Hi Priya,

For RFC execution the user needs to have S_RFC authorization.

Hi Priya,

1. To execute the RFC in R/3 system Portal Username should have R/3 sytem access thats is enough.

2. No need of any special authorization.

For webdynpro we have to create two JCO destination.

one for Application and other for meta data.

Try this option:

WD_MODELDATA_DEST- Use Ticket option.

WD_METADATA_DEST- Use Username/Password option. Service user name and password of the R/3 system: Administrator has to create this users.
