Error description
Only one clustering index is allowed for a table. But if target environment already has a clustering index and Source defines another clustering index without changing existing index to NOT CLUSTER, Object Compare generates incorrect apply job that fails with SQLCODE = -623. Object Compare should issue an error message when index cannot be defined as clustering index.
