Field help (MGDDSYFEA)
When a targeting is selected, this tick box is used to indicate whether a target characteristics read is required. This information is in effect dynamically interpreted on each selection of a new targeting in the left-hand grid. When large volumes are in play in the table and it is necessary to pay attention to the nature of sample, the reading of these records can have a negative impact on the navigation in the grid. Un-ticking this box makes the navigation between targetings instantaneous. This tick box only affects the qualification of the four fields in the "Characteristics" section. The presentation support and the sample nature become available for viewing. By default, this box is always ticked on opening the window.
