If it's a structure you cannot perform a SELECT statement...

What's the name of this deep struc?

Hi,

In a Deep structures you can have data, tables, structures, objects and etc. We can create a Deep internal table based on deep structure.

Also is possible create Deep transparent table. And you can use the SELECT with a deep table.

There is no difference with Deep transparent table and Deep Internal table.

Look at follow example, i hope it solve your doubts !


REPORT zmar.

  PUBLIC SECTION.

    DATA e_sflight TYPE sflight.
