1. Go to AOT/Queries
2. For e.g. AssetBudgetModel\DataSources\Assetbudget\fields click the data source right-click Fields, and then click Properties.
2. Set the Dynamic property to No.
By default, the Dynamic property is set to Yes and returns all fields from the table, map, or view. This makes maintenance easier because you don't need to change the query if a field is changed in the underlying data source. However, restricting the fields returned by the query is better for performance because unused data is not returned to the client each time the query is run.
