/**
 * Builds a sub-query to select the maximum business object data version.

 * @param builder the criteria builder//from w w w  .jav  a2  s. com
 * @param criteria the criteria query
 * @param businessObjectDefinitionEntity the business object definition entity that appears in the from clause of the main query
 * @param businessObjectFormatEntity the business object format entity that appears in the from clause of the main query
 * @param fileTypeEntity the file type entity that appears in the from clause of the main query
 * @param businessObjectDataEntity the business object data entity that appears in the from clause of the main query
 * @param businessObjectDataVersion the business object data version. If a business object data version isn't specified, the latest data version based on
 * the specified business object data status is returned
 * @param businessObjectDataStatus the business object data status. This parameter is ignored when the business object data version is specified. When
