  • How to create and edit a table type for an internal table in the new, form-based Table Types editor
  • How to use this table type to retrieve data from a database table

Table types can also be defined in, for example, an ABAP program or class. The differences between the two approaches include:- Table types in the ABAP Data Dictionary are maintained in a form-based editor, table types in ABAP in a text-based editor- Table types can only be used by other Dictionary types if they are defined in the Data Dictionary- Table types in the Dictionary are stand-alone objects, whereas table types in ABAP are always part of another Repository object
