Check used capacity of every custom field

Dear experts, 

firstly, I would like to ask about the capacity that particular custom field use. I know, that business context has certain capacity and that by creating a custom field in it, it will consume some capacity, but I would like to know the exact percentage of the capacity that every custom field takes.
Is it possible to check it somewhere? In the app Extensibility cockpit I can see only the percentage of used capacity, but that is it, and it is not enough for us. 

My second question is about lowering the number of characters of custom field. 
From my experience it is not possible, as there will be error message saying that I cannot decrease the value. BUT, is there any other way how to do it instead of deleting the field and creating the new one? From my understanding deleting the field that is already used will also delete data inside, which can be dangerous in production. 

Thank you very much for your help.

Hi Veronika,

Here are the general guidelines about extensibility capacity:

About Business Contexts

"On average, you can create 100 fields per business context and you have 1000 characters available for all business contexts, except Coding Block. You can see the currently available space when adding a new custom field in the Business Context Capacity indicator. The amount of capacity that a field requires depends on its type and the defined length. You can also check the remaining capacity in the Extensibility Cockpit."

As you probably found, you can drill down into the contexts on the Extensibility Cockpit to see the custom field for example.

I don't see an UI that provides the "you have used x number of characters of your available capacity" but perhaps you can log a ticket with support and they may be able to check it.

On your second question, this note unfortunately answers your question:

2992710 - Unable to decrease the length of a published custom field

For reference:

3055336 - How to delete a Custom Field?

So the only way would be to capture all the values of the custom field, delete the custom field, create a new one of reduced length and then repopulate. If you expose the object through an API, this might make it easier to do, but still not trivial.

i hope this helps

Thank you

Jerry
