Hi all,
basically the title, I am new to zoho projects and trying to get my head around some basic principles. 

Unfortunately I have not found this information via the search option and after deleting yesterday some Phases I had created in the Phases tab, to find out, that that will delete these Phases also in all of my projects, I am more cautios doing any updates and losing data.

As I understand ZP uses the task ID to identify tasks and also create the dependencies between them.
I don't like the automated Nr generation because if I add or change some tasks the numbering gets out of order and creating dependencies in the list view is a big pain.

Maybe it would be better to have the task rows numbered and updated automatically like in Excel or MS projects and to have the Prefix and ID additionally (to have the backend link) BUT disabling it from being visible.

Having said that, I see that the Task Prefix & ID can be turned off in the settings, but I am afraid this change might affect all dependencies in my current projects and templates.

So my question is, what will happen if I turn off this feature (see image attached)?

Any hint or explanation would be great!

Thanks!
