I'm running SAP R/3.
The table E071 stores objects from transport requests. There is a 4 character field in it called OBJECT that stores the object type. Like PROG for program, TABD for table, etc.  
I have an internal table with objects selected from E071.
The objects with type TABL can both be a normal structure and an append structure.
In SE11, when you view a structure object, if it's a normal structure, it shows a text that says Structure by the object name. And if it's an append structure, it shows Append Structure there.
So there is a way to differentiate them.
How should I go about differentiating them inside my program? Is there any technical detail that is different between these two?
