Z Program of subtype being incorrect??

Question

Hi experts.
I've created a Z subtype of object BUS2009 and I have some problems regarding the containers.
Well, It's a little complicated so I'll try to expose it as easy as I can.
We have a problem with the Z-Object because of the "get_property" function on the original object program. As you know, when you create a subtype of some object, it requires a new program name, it's supposed that the code you write in this new program is added to the existing one (the one in the father object), so if you declare new methods, they are included on this new program, but you also have access to the methods of the father object.
Well, when I debug some of the methods of the original object, there is a table, "_eban", that is used to retrieve the atributes of the object in the "get_property" code. But when I debug my own method, this table seems to be empty...I don't know why because the "get property" is supposed to be executed even if I call de Z version of the program in the subtype. Isn`t it?
What do you think about that?
Thank you all.

Hall Ismael,
the field <tablename> and the form get_table_property_xxx is generated when you create (new) object attributes with reference to a database table.
These attributes are then stored in <tablename> as a cache. This function is executed for the first attribute on reading. So when you want to ensure, that you have current data, use the following statment in your method:
swc_get_property self '<your-table-property>' prop.
If this call returns with sy-subrc = 0, the complete _eban is now filled.
Best wishes,
