Rows based on days

So in Constellation,depending on a property called no of days that many number of embedded rows, should be created to enter data, and user should not be able to add or delete rows, and when days changes this too also should change all should happen in same view only, how can we do it via activity

@SAITARUNSANTHOSHN17115422can you describe your attempted solutions please?

Have you maybe tried Form Refresh functionality: https://community.pega.com/conversations/user-experience/form-refresh-settings%3A-the-artist-formally-known-as-“on-change%2C-run-data-transform

Does it need to be an activity? Why?
