Hi DJ another nice method to use containers. Is that you connect from VSC to the BAS Container. With the vsc extension "Remote access for Business Application Studio. The great thing is that you have access to all the services running on BTP such as the DB and destinations. Which is very handy for testing.

Hi DJ, I just watched the first 2 session and it is really amazing. Looking forward to join the upcoming one. Thank you for sharing this❤

All this is cool. What if i want to update material master data in s4 cloud through a post call to the standard api. Can i do that using a cap service?
Basically, how do we use the release odata v2 or v4 apis in our cap service and then add a bit of Ui and create a fiori app to serve our purpose?

Hi DJ, I have a question please: When we should use CAP instead RAP?

[SeemaSharma-mvzv]

Hi DJ, I have just started watching the series. I have downloaded folder capb2b as you advised in session 1 in VS code but I do not see any dev container in VS code.

how do you get the tree unix command to run at your terminal? thanks!

After I run cds init command, it adds eslint.config.mjs instead of .eslintrc. Am I skipping any step?

Actual Version of CDS: cds add samples (sample and tiny-sample was removed)!
