And how would you tell/see the difference in statements? What if you have a recordlist with both a structure and a record?

Dislike ... same as Joost says

1) "And how would you tell/see the difference in statements? What if you have a recordlist with both a structure and a record?"

To determine the difference, add a prefix to your variable name,

For example

Employee <--- this is an entity record
EmployeeStruc <--- this is a structure record
EmployeeList <--- this is an entity record list
EmployeeStrucList <--- this is a structure record list

2) What happens when you want to use the same record structure as an entity in a public web service? you might have an employee entity then you might have an employee structure to be used by your public web service.

Currently you can not have the same name. So you can not achieve this task.

Please don't.

If this must be used, do it to combine the same structures that are used in multple webservices instead of creating x1, x2,x3 etc.
