TYPE-POOLS tpool.
Includes the types and constants of a type group. If the type group tpool
has already been included, the statement is ignored. You can only maintain a type group via the ABAP/4
Dictionary (using Transaction SE11). You introduce a type group with the
TYPE-POOL statement. Since the types and constants
specified in a type group have global validity, you cannot use the statement within a FORM or FUNCTION.
