%%information You may use more than one filter on a Where Clause. If you do use multiple filter

;[Operator|COMPARISON_OPERATOR]:This field allows you to provide an SQL statement to further filter the information. 
;[Value|VALUE]:This field completes the SQL statement of the previous field.\\  \\This field holds information used to filter the where clause against. For example, it may be "Active" if the where clause is to filter a list of employees based on their employment status.

The Column, Operator and Value fields are used together to create a precise filter for information. 
For example, if you wished to only see in the LOV positions that are in the Finance department, you would insert the following information in those fields: 
*Column = ID.DPS_ID 
*Operator = equal to 
*Value = Finance
