Connecting NWDS to ECC

Former Member
0 Kudos

Hello All,

Is there a guide to help configure NWDS to connect to the ECC instance? I am trying to import some BAPIs into Web DynPro but when I get to the ECC logon screen, I am getting user/password incorrect message. I am VERY sure that both are correct because I am able to logon using SAP GUI using the same combination.

I am wondering if there are network issues (like Ports blocked etc) that are preventing me from logging on.

Thanks,

Sameer

Hi Sameer,

You'd need to create/maintain JCO destinations in your runtime systems then you can use it in NWDS. Please check out this weblog for more details

Hope it helps.

Hi Sameer,

Here is a help link to start with:

http://help.sap.com/saphelp_nw04/helpdata/en/6a/11f1f29526944e8580c5e59333d96d/frameset.htm

Points to check:

- Please check if your ECC system is up and running - also try to ping to this server from the system on which you have the NWDS installed.

- Please check if you have PUBLIC as a logon group on your ECC system

- Also, try to add the following entry in your "services" file (C:\WINDOWS\system32\drivers\etc)

sapms<SID> 3600/tcp

(The port could be either 3600 or 3601).

Also, the user you are trying to use should have RFC authorization to Function Group SYST in the backend system.

Hope that helps !!
