Select invalid variable types
AnswerClick to flip back
A
VARCHAR1
B
CHAR2
💡 Explanation:
VARCHAR2, CHAR, INTEGER, and NUMBER are standard, valid variable types in ABAP and Oracle databases. VARCHAR1 and CHAR2 are not valid types - the correct forms are VARCHAR2 (not VARCHAR1) and CHAR (not CHAR2). The question asks specifically for invalid types, so B and D are the correct selections.
