Hello,

I'm confused, are you using DEV or APP studio? Can you add a screen shot.

Please find the below article which might be helpful.

Hi Shreyas,

I think you are on Pega Platfrom app. You won't be able to create/update any thing in this app. Please create an application if you have not already and switch to that application. 

Here is how you can create an application: https://community.pega.com/knowledgebase/articles/implementation-methodology-and-dco/creating-applications-new-application-wizard
