How to retrieve all valid values for a element in a specific table?

[EricZ1]

I am trying to retrieve all valid values for elements in different tables. I have noticed that if a record is created with an invalid value for a element using the Table API (e.g. incident table -> category -> "invalidcategory" value), the record will be created but its value will be a default value ("inquiry").

I found that you can use the sys_choice endpoint to retrieve options for specific tables, but the problem is that sometimes restricted values are inherited from a "parent table" (e.g. 'incident' inherits from 'task' values for the 'upon_reject' element). However, at other times the child table does not inherit from its parent table. For example, both 'task' and 'incident' have a 'short_description' element, but only the short_description for 'task' is restricted.

How do I retrieve all valid values for elements belonging to a specific table, including those inherited from the parent table if any?

Hi Basheer,
Thank you for the reply. I am primarily interested in the REST APIs. Is there a method/endpoint to retrieve valid values for fields in a table (besides sys_choice which does not seem to return inherited values and the like)?
