Some expressions return different results in QlikView Desktop and Access Point. The problem is generally related to Section Access as when this is removed the issue is not present.
Environment
This is caused by a known limitation in how NULL values are managed between the AccessPoint (QlikView Server) and QlikView Desktop.
Resolution:
The most common workaround or practice, in this case, is to transform the missing values (null) into zero-values instead in the script by using the "nullasvalue" keyword and assign nullvalue=0. This is a fairly simple approach that will work fine in most cases.
Here is an article that describes how to use "nullasvalue": NullAsValue (Help.Qlik.Com)
