Description

PivotTable reports can contain OLAP queries with references to User Defined Functions (UDFs). UDFs can be compiled executables, therefore posing a potential security threat. With this setting you can either (1) allow all UDFs in OLAP queries to execute with no IObjectSafety check, (2) allow only UDFs where the developer has used IObjectSafety to mark the UDF as a safe executable, or (3) disable all UDFs from executing in OLAP queries. The effect of setting this key is for Excel to pass the selected value to the OLAP provider.
