How To Fix SWF_EXP_001024 - Unexpected character(s) '&2' at end of expression '&3' at position &1

SAP Error Message - Details

• Message type: E = Error

• Message class: SWF_EXP_001 - Expression Service Messages

• Message number: 024

• Message text: Unexpected character(s) '&2' at end of expression '&3' at position &1

What causes this issue?

The character chain &V3& should be an expression. However, the check
established that the first character in the character chain up to
position &V1& already constitutes a complete expression. The subsequent
character &V2& therefore triggers a syntax error.

System Response

The expression contains a syntax error.

How to fix this error?

Check the expression. Note that the following characters have a special
meaning and must only be used in constants when the constant is enclosed
by inverted commas: '&[] '{}"%'
Typical error situation when entering constants:
A constant itself contains an inverted comma or quotation marks (' or
"). Within a constant, use instead the non-reserved ` or ? character. If
you delimit a constant with quotation marks ("abc"), then this constant
may contain the ' character ("abc's great").
Always use the delimiter characters symmetrically. Incorrect:
''Teststring'. Correct: 'Teststring' or "Teststring".
