Number Generators

Number Generators are designed to assist users in populating a feature class field with a unique value.

The GIS Task that syncs your GIS data in your Feature Service into Lucity will automatically trigger any number generators when it runs.

Click the Add New Number Generator button.
A new record will be added to the grid.
Select the record in the grid and fill out the Number Generator Info section at the bottom.
* Populate the Field to AutoNumber- This is the field that will be auto-numbered.
- This should be a text field, large enough to support the numbers that will be generated based on the settings on this form.
Populate the Buffered Number Length. This causes the number to contain buffered zeros. Enter the number of characters desired.
- Optional. Example, if a buffered length of 5 is entered, and if the auto-number generated is 985, the resulting auto number that will be populated is 00985. This may allow for easier number sorting.
Include Prefix Settings.
- None: This will be marked by default. If this button remains marked, there will be no Prefix for this AutoNumber field.
- Use Set Prefix: This will allow specifying a prefix in the next number gird and a separator character.
- Use a polygon feature class to create a prefix: Uses a Polygon Feature class field to generate a prefix based on a features spatial relation to the polygon feature class.
  - Service that contains related layer: Populate with the name of the feature service that contains the polygon layer the number generator will use. (Only necessary if the related layer is not in the same service)
  - Polygon Layer: The polygon feature class layer that the prefix is based on.
  - Field that Contains prefix value: The field in the polygon feature class that contains the value that will be used as a prefix.
Separator Character: Optional. Characters entered into this field will be between the Prefix and Autonumber. This is available only if using a prefix.
Click the Generate Next Number button to set the correct start number.
- If the prefix setting option is set to None or Use Set Prefix then only one next number record is allowed in the grid.
- If the prefix setting option is set to Use a Polygon Feature Class then an unlimited number of next numbers can be set. One for each polygon in the feature class.
  Note: When a new feature is created in the selected feature class if no Next Number is set the number generator will set the new feature to 1 and set a new Next Number to 2, and continue from there. The same is true if a Polygon feature class is used.
This information will be saved when you click on a different feature class.
Note: Number Generator can be edited anytime after saving them
