hello Asif
this is very little information to go on...
As i understand the issue
Step 1: you created a repository workspace by right clicking on the 'Repositories' tab
Step 2: you created a new XS project
Step 3 : (my assumption) you shared the XS project
Step 4. you see the project folder in the repository workspace and try to check it out...
Also,
(my assumption) you are the only person working on the project
Is my understanding correct?
if correct, then there is nothing to check out!!!!
A check out downloads content on the HANA Repository (stuff you see in the System tab under the Content node) to your local repository (stuff you see under the 'Repositories' tab)
As you are the only person working the local and HANA Repository is always in sync hence nothing happens.
Try this
Go to Systems tab and expand the Contents node
Find the root folder of your XS project and *under it* create a new package
now check out
you will find your project shows the additional package as a folder
Warm regards
aadi
