This below shown code doesn't work because I get the message "p_ttest is not an internal table"
How can I get it working ?
TYPES: BEGIN OF tty_test,
name(10) type c,
zahl type i,
END OF tty_test.
data ttest type table of tty_test.
perform training changing ttest .
write: ''.
FORM training changing p_ttest.
data xyz type tty_test.
xyz-name = 'John'.
xyz-zahl = '23'.
append xyz TO p_ttest.
ENDFORM. "
