Append the NOLOCK table hint after the table definition
Use the steps below to apply the SQL NOLOCK option after the table definition.
           Note: 
           
         This is a global setting that applies to all catalog and datamart objects. When an object has a user-defined After Table Definition code, DWD will override the global setting and use the object level code instead.
- In the DWD Designer, navigate to
 - Select No locking on tables.
 - Compile the catalog/datamart objects.
