In helicalinsight few values are restricted in filter expression for the security reasons.
If you pass that restricted keyword you might get the below error
Error: HCRException: The filter value is unaccepted, please try with someother value.
In case if you compulsory want those values to be passed in filter expression then navigate yourself to this location
/HelicalInsight/hi/hi-repository/System/Admin
Here you will find ‘defaults.properties’ file
![Values/Keywords that are restricted to pass in canned report parameter filter expression](https://www.helicalinsight.com/wp-content/uploads/2021/03/ValuesKeywords-That-Are-Restricted-To-Pass-In-Canned-Report-Parameter-Filter-Expression.png)
you will find the below keywords
CREATE|DELETE|DROP|INSERT( +INTO){0,1}|MERGE|SELECT|UPDATE|UNION( +ALL){0,1}|FROM|WHERE|SLEEP
try to remove the keyword that is restricting your filter expression and save it.
Refresh the tomcat and try now.
