SAP NetWeaver – Step by Step Guide for NWDI Configuration

SAP NWDI (NetWeaver Development Infrastructure) provides development environment for large teams where it is difficult to manage SAP Java WebDynpro based development components and respective code, especially when developers are situated at different geographical locations. NWDI provides common and online WD component + code repository that can be accessed from anywhere in enterprise premises.

Following are steps which covers complete details from initial NWDI configuration to start using tracks in SAP NWDS (NetWeaver Developer Studio).

1.    Creating and assigning required Roles and Actions in portal UME 

Create two groups for NWDI users in Portal UME.

• NWDI.Administrators
• NWDI.Developers

Create NWDI_Admin and NWDI_Developer users and add these users to corresponding groups NWDI.Administrators and NWDI.Developers simultaneously.

Search for NWDI.Administrator Role else Create and Assign it to NWDI.Administrators Group. Similarly search for NWDI.Developer Role else create and assign it to NWDI.Developers Group.

Open NWDI.Administrator Role and assign following Actions

• CBS.Administrator
• CMS.Administrate

Open NWDI.Developer Role and assign following Actions

• CBS.Developer
• CMS.Display
• CMS.Export

2.    Assigning SLD Roles to Groups 

For respective groups assign corresponding security roles.

• NWDI.Administrators               LcrInstanceWriterAll
• NWDI.Developers                    LcrInstanceWriterNR

To assign above said security roles to NWDI groups, Go to Visual Administrator to set up user privileges for J2EE Engine. Visual Administrator can be opened via following path <SAP-install-dir>\<SID>\JC<instance no.>\j2ee\admin\go.bat

• Login as Administrator
• Open the navigation tree on left side of screen and go Server -> Services -> Security Provider
• In the right-hand window, choose the tab Runtime -> Policy Configuration -> Security Roles.
