Set analysis expressions in different visualization objects stops working after upgrading to QlikView 12.20 and QlikView September 2018 from earlier versions. Typical symptoms are error messages "Incomplete visualization", "Invalid dimension/ measure" or charts showing no values. Such errors are observed onset analysis expressions with literal matches (using single quotes to define a value list), for example:
In all of these, the expression editor may not detect any syntax error in the expression still says that the expression is OK.
Note: This is also related to the issue in Qlik Sense 3.2 and higher where "error in expression ')' expected" occurs in an application or shows up in the log files.
Cause
In Set Analysis syntax, single quotes denote literal match (exact match of textual values) and double quotes denote search string (case insensitive, can apply wildcard symbols). More details are discussed in the following community post: Quotes in Set Analysis
From QlikView November 2017 (12.20) and Qlik Sense September 2018, items QLIK-87570, and QV-16253 were reported where Set Analysis fails to interpret single quotes and returns unexpected results in certain cases.
Recommended work-around while waiting for the defect fixes is using double quotes instead of single quotes in Set Analysis expressions.
Environments:
QlikView November 2017 (12.20) and later
Qlik Sense September 2018 and later
Resolution:
Fix version:
Qlik Sense April 2019 QlikView 12.40 IR QlikView 12.30 SR3
Workarounds:
1. Change single quotes in the value list of Set Analysis expressions to double quotes. This is the recommended approach until related defects are fixed. For example:
