Replication from materialized views to regular tables in Oracle 8i,9i & 10g is supported in 5.3.
Shareplex 5.3 supports replication of materialized views to regular tables, if one is included in the config file, it should not cause Post to stop due to ORA-01732. There are no known parameters, at this time, or known bugs known for replicating from materialized views to tables.
Solution 6849 discusses/resolves ORA-01732: Data manipulation operation not legal on this view. Materialized view has been included in config file and Post stopped as the DML is not permitted on earlier Oracle versions.
ORA-01732: data manipulation operation not legal on this view Cause: An attempt was made to use an UPDATE, INSERT, or DELETE statement on a view that contains expressions or functions or was derived from more than one table. If a join operation was used to create the view or the view contains virtual columns derived from functions or expressions, then the view may only be queried. Action: UPDATE, INSERT, or DELETE rows in the base tables instead and restrict the operations on the view to queries.
