Answer / guest

when refering to type-pool you need to use TYPE
declaration, and LIKE is used to refer your already
declared variable. And for declaring native types 'N' 'C'
you cannot use LIKE there.

data: matnr like mara-matnr,
matnr1 type mara-matnr.

will not make any difference in the program. however

data: matnr type mara-matnr,
matnr1 like matnr. when the attribute of matnr
changes will affect matnr1 also.

and LIKE statement become obselete in Object programming.
you can use TYPE statements only there.
