If you still want to create new list members which do not fulfil the criteria above, you'll have to do it using 'Edit > Insert' as shown below, either on a published list or published module in a dashboard.
Re: Unable to create button to add new entries into line item by using action
If I am using another list as parent heirarchy, then action button is working, but the data in modules taking parent as main thing, so data cant be seen. Eventhough it is working for capex , it is not working for marketing inputs.
Because, by default it is taking as new list parent so, the data can't be seen now.
