User Defined Types

You can declare user defined data types in your ABAP/4 programs using the TYPES statement.

• In doing so you can refer to
  • pre-defined or user defined data types using TYPE or
  • the type of data objects within the program or ABAP/4 Dictionary objects using LIKE.
• Note that you can use the additions TYPE and LIKE for any type declarations.
