Unique Key Dialog Box Properties

This topic describes how you can use the Unique Key dialog box to select a unique key for a real time chart.

Server displays the dialog box when you select the Incremental Fetch button in the Bind Data screen of a chart in the Web Report Wizard, or select the button in the Insert Chart dialog box, Chart Wizard, or Convert to Chart dialog box.

Resources

Lists all the elements in the business view used by the real time chart.

Sorts the view elements in the specified order from the drop-down list. Once a user changes the order, it will be applied to all the resource trees where business view elements are listed for this user.

• Predefined Order
  Select if you want to sort the view elements in the order as in the Business View Editor of Designer.
• Resource Types
  Select if you want to sort the view elements by resource type. Namely, category objects come first, then group objects, then aggregation objects, and at last detail objects.
• Alphabetical Order
  Select if you want to sort the view elements in alphabetical order. Logi Report sorts the elements that are not in any category first, and then the categories. It also sorts the elements in each category alphabetically.

Launches the search bar to search for view elements.

See the following options in the search bar:

• Text box
  Type the text you want to search in the text box. Server lists the values that contain the matched text.
• X
  Select to close the search bar or clear the typed text.
• 
  Select the button and Server displays more search options.
  • Highlight All
    Select if you want to highlight all matched text.
  • Match Case
    Select if you want to search for text that meets the case of the typed text.
  • Match Whole Word
    Select if you want to search for text that looks the same as the typed text.
• 
  When you selected Highlight All, you can use this button to go to the previous matched text.
• 
  When you selected Highlight All, you can use this button to go to the next matched text.

Adds the selected fields to the Unique Key box.

Removes the selected from the Unique Key box if they are not required.

Unique Key

Lists the fields you have added as the unique key, which is used to guarantee there are no two records with the same unique key value in the real time chart.

When a real time chart is specified with a unique key, each time when the chart automatically updates itself, the data that has the same unique key value as the previous loaded data records will be filtered and only data with different unique key value will be added to the chart. For instance, if you add the fields Country and Product ID as the unique key of a real time chart, when a record with the product ID 1 in USA has already been loaded into the chart, no more records of this product ID in USA will be added to the real time chart because they have the same unique key value. The most common usage is with a time field so when a time is part of the unique key the data in the chart will be updated each time new records are added to the database with more recent times.
