Acumatica Data Field Names

Is there a place I can go to see all the field names for a given entity (ie: StockItems).

My reason is that I have some sync processes that download StockItems via the rest API. However, the properties/field names that the rest API returns are different than what I see in a Generic Inquiry. 

For instance, in the rest API, the field name for Description is “Description”. In the GI, its called DESC.

I was hoping there was some sort of way I can see how those mappings work. I am porting some of these REST Api calls over to oData and am unsure what the fields are called in the Generic Inquiry UI screen.

Thanks!
