TYPE-POOLS
Basic form
TYPE-POOLS typepool.
Effect

the types and constants of a type group. If the type group typepool 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 .

TYPE-POOLS VERI1.
DATA X TYPE VERI1_TYP1.
