In SAP Build Apps, in which of the following cases does the IS_EMPTY function return true? Note: There are 3 correct answers to this question.

Question

Options

• AIS_EMPTY(NAN)
• BIS_EMPTY(0)
• CIS_EMPTY("a")
• DIS_EMPTY("")
• EIS_EMPTY(0)

• A
  72% (23)
• B
  9% (3)
• C
  19% (6)

Explanation

IS_EMPTY returns true for values that are undefined or have no meaningful content. NAN (Not a Number) is considered an invalid/empty value in SAP Build Apps, so IS_EMPTY(NAN) returns true (A). An empty string "" contains no characters, making IS_EMPTY("") return true (D).

Note: There appears to be a typo in the question - options B and E are listed identically as IS_EMPTY(0), which is contradictory since B is marked wrong and E is marked correct. Option E is most likely meant to be IS_EMPTY(null) or IS_EMPTY(undefined), both of which return true because they represent the complete absence of a value.

The distractors explained: IS_EMPTY(0) (B) returns false - zero is a valid, defined numeric value, not an absence of data. IS_EMPTY("a") (C) returns false - a string with content is not empty, regardless of what that content is.

Memory tip: Think of IS_EMPTY as asking "Is this value unusable or missing?" - NAN is a broken number, "" is a string with nothing in it, and null/undefined mean "nothing was ever provided." A real number like 0 or any non-empty string always counts as real data.
