Difference between records.incident vs reference.incident? Flow Designer

[kgomez222]

hey all, I'm new to ServiceNow and I am currently experimenting with flow designer, particularly sublfow inputs. 

I've been experimenting between the input types and I'm curious what is the difference between these two?

I currently have an approval action  and I'm attempting to feed it the record that was created in another flow, but i cannot use the second input as the record in the approval action, but i CAN use the first reference record input. 

i can see from the data pill that records.incident data type is 'records' but i cant seem to find anything in the docs about this data type.

Hello @kgomez222 

Basic Diff is 

Records.[Table] data type
Stores one or more Sys ID references to records in a specific table.

Reference.[Table] data type
Store a single Sys ID reference to a record in a specific table.

Thanks
