What is the "auto increment" input type?

[Patrick71]

Was experimenting in flow designer and found this subflow input type but couldn't find any information on it at all.

All I managed to find out when tinkering is that

typeof fd_data.subflow_inputs.autoincrement returns String.

It's a field type available in ServiceNow but only used on a few tables

instanceName.service-now.com/sys_dictionary_list.do?sysparm_query=internal_type%3Dauto_increment&sysparm_view=advanced

The field type doesn't appear to be active/visible any more

instanceName.service-now.com/sys_glide_object.do?sys_id=e69906fc0a00011119c2ffcadcfd240f&sysparm_view=advanced 

I didn't find much online besides this definition

"Looks for the highest number of this field on this table and automatically attaches the next number in line after saving the record."

And it's not in ServiceNow documentation, so I would conclude that it's a legacy field or system level field, and it's not something we would ever use.
