NWDI is SAP’s own version management
tool that supports sliced development.
Following are its major components:
1) Change
Management System (CMS). Which is responsible for maintaining version
of your software.
2) Component Build Service (CBS). Which is required for the building of software
components
3) Design Time
Repository (DTR). Which maintains the code.
Now, let’s see how do we create a track.
1.
First step is to create a new product version.
This is a parent
component that’ll hold software unit (SU) and software components(SC).
Product, Software Unit & Software Component are created in SLD and
the track is created in NWDI Landscape configurator.
Steps
for creating a product:
SLD > New Product Version > enter required data > Create an SU > Create an SC and keep production state as started
2. Now,
we need to add dependencies to SC that will support the development and
building of a component. There are 3 dependencies we must add. However,
if your development is somehow related to Guided Procedures, you also
need to add CAF related dependencies in addition to 3 standard dependencies.
Steps
for adding dependencies to SC:
Go
to Software Catalogue > Software Component tab > Select
application SC and navigate to Dependencies tab > Set context to
Build Time > Click on Define prerequisite software components >
Search and add following dependencies.
1) SAP J2EE ENGINE <release version> | SAP-JEE
2) DI BUILD TOOL <release version> | SAP_BUILDT
3) SAP JAVA TECHNOLOGY SERVICES <release version> | SAP_JTECHS
After this, our application component is ready to be used in track in NWDI
3.
Here we will reserve a NameSpace for our developments. NameSpace and
NameSpace prefix are used while creating a Development Component (DC).
It make sure that everything developed is clubbed under same NameSpace.
This is to avoid conflict in the component build and transports. You can
skip this step if you want to use already created NameSpace.
Go to SLD > Name Reservation > Define Name Prefix >Specify name category and name prefix and choose create
Here
we did not create a new NameSpace, if you want to create a NameSpace,
you can click on New NameSpace and use it while creating Name Prefix.
4. In this step, we are going to create a track, provide domain data, track data and define runtime systems.
Go to NWDI (http://<host>:<port>/devinf)
> CMS > Landscape Configurator > In right hand side, click on
New Track > You need to have CMS & CBS URL and password for
further steps > Fill domain and track data > Here you need to add a
software component that we created in SLD to the track > Search for
the SC and add it track.
PS: Make sure all three dependencies are also added along with SC and are in Green state
Now,
go to runtime systems > and select the check boxes for system you
wish to define. For e.g. if you want to configure development, test and
production, select the corresponding check-boxes. Select Configure
without wizard > provide user id and a password > Similarly add
other runtime systems
5.
This is the final step of NWDI track creation process.
Here we are only
going to check-in the dependencies to the development system that we
defined in runtime systems of landscape configurator.
Go
to Transport Studio > Check-in tab> Select all three dependencies
and click on Check-In > after successful Check-In, these
dependencies should be moved to Development system.
You
can leave these dependencies in waiting for import state and import
them along with your released development activities. Its stage will not
hamper your development.
With this, you have successfully
- Create New Product
- A software unit and a component
- Added dependencies to SC
- Defined a new track and added an SC to track
- Configured runtime systems
- Check-In all dependencies to development system
You are all set to start development in NWDS. I feel it is equally important to know how to delete NWDI track and its DTR workspace. You can read more on this here How to delete NWDI Track and DTR Workspace and also more on NWDI Troubleshooting
Screen shots will be added soon....
