Expression rule not returning any value in a column of process report

Question

Hi Team, 
 I have an expression rule to fetch string from a database, its working fine in ER editor and interfaces, but If I call that rule inside expression editor in a Process Report column it doesn't return a value. 
 Kindly help me 
 
 Thanks

Not only can you not use local variables, you also can't call any rules or expression rules using keyword syntax for parameters, or it breaks. I forget whether this applies to the rule-call placed inside the report definition itself, but in the past I've proven that if your rule calls other rules (even very simple ones) using keyword syntax rather than simple positional parameter passing, it won't work at all in the portal report.
