 Table filters are not supported on binary data type columns. A binary data type is the Postgres data type `BYTEA`. In addition, table filters are not supported on Advanced Server columns with data types `BINARY`, `VARBINARY`, `BLOB`, `LONG RAW`, and `RAW` as these are alias names for the `BYTEA` data type.
 
+**Filtering Restrictions on Operators**
+
+XDB supports modulus operator (denoted by %) to define a filter clause. However, the following restrictions apply:
+
+- You can have only a single filter condition using the modulus operator
+
+- You cannot use it with any other conditions using `AND` or `OR` operators
+
+XDB supports the modulus filter in the following formats:
+
+`deptno%3=0`
+
+`@deptno%3=0`
+
+
 ## Roadmap for Further Instructions
 
 The specific details on implementing table filtering depend upon whether you are using a single-master replication system or a multi-master replication system. The following is a roadmap to the relevant sections for each type of replication system.
