Error when using "inlist operator" in the query filter of Webi 3.1

Hi,

We are currently in the process of migrating Deski to webi (BOXI 3.1).

The problem is, Deski is using the "inlist" operator which is working fine but after migrating to webi the inlist operator in the query filter is throwing the below error,

*Error Message :*

A database error occured. The database error text is: ORA-00907: missing right parenthesis. (WIS 10901)

Appreciate your assistance on this.

Thanks !

Regards,
