Default number of rows that query services return. The query services are services in the wm.tn.query folder. An input variable to the query services allows you to specify a maximum number of rows to return from a query. If you do not specify the number of rows to return when you invoke a query service, the query service uses this property. If a query returns more rows than allowed by this property, the query service silently drops the rows that exceed the number you specify. The default is 0, which indicates no maximum.
