Fields in add attribute details page

The description of all the fields and their details, seen in the Add attribute details page, are as follows:

Table 1. Fields in Add Attribute Details Page
Field Name	Description
Display name	Specify the label to identify the attribute for users. For example, "Interest Rate". Double quotes in attribute display names are not supported.
Internal name	Specify a name to identify this attribute when you write a query or custom macro. Use the same name as the Attribute display name, but without any spaces (for example, "InterestRate"). The internal name must be globally unique, must start with an alphabetic character, cannot include spaces, and are not case-sensitive.
Description	A description of the attribute.
Form element type	Specify the type of data to be stored in the attribute field for offers. Important: After you add the custom attribute, you cannot change its data type.
Form element type Text field - String	Specify a maximum string length to indicate the maximum number of bytes to store for any value of this attribute. For example, if you enter 32, single-byte languages such as English store 32 characters but double-byte languages store only 16 characters. Important: Decreasing the length of an existing attribute truncates existing values, which, if the field is used for matching purposes, can adversely affect response tracking.
Form element type Text field - Numeric	Specify the number of decimal places to display to the right of the decimal point. Note: If you decrease the value for an existing attribute, the display is truncated in the user interface. However, the original value is retained in the database.
Form element type Text field - Date
Form element type Text field - Currency	Specify the number of decimal places. Important: The currency value reflects the number of decimal places that are customarily used in the local currency. If you specify a number for decimal places that is less than the number commonly used, the currency value is truncated.
Form element type Select box - String	Specify a Maximum string length Optionally, check Allow addition of list items from within edit forms to allow any user to add new unique values to the list of available values when creating or editing an offer template, or an offer that includes this attribute. For example, if a Select Box on an offer template contains the values Small, Medium, Large, a user could add the value Extra Large when creating an offer or editing the offer template. Important: After the offer template, or offer is saved, the user cannot remove the new list item. The value is saved in the custom attribute definition and is then available to all users. Only administrators can remove items from lists, by modifying the custom attribute. Populate the Source list of available values to specify which items are available in the Select Box. Enter values in the New or selected item field and click Accept. To delete a value, select it in the Source list of available values and click Remove. Optionally, specify a Default value for the Select Box. The default value is used on the offer, unless the user specifies a different value when creating or editing the offer. Specify the Sort order to determine how values appear in the list.
Form element type Text field - Integer	You can use the Integer attribute type to fill numeric data without decimal places.
Form element type Check box - Boolean	You can use the Boolean attribute type to select or deselect a checkbox (for example true or false) for the attribute. Note: Currently the systems leveraging Centralized Offer Management treats the Boolean attribute as numeric with possible values of 0 or 1. Here, 0 means FALSE and 1 means TRUE. So, if you are parameterizing the Boolean attribute, or exporting the attribute, it will be represented as 0 or 1.
Form element type Picker - URL	You can define the attribute of type URL. When integrated with Asset Picker, you can provide a URL for searching content from target content management system. For more information, refer Unica Asset Picker Administrator's Guide.
Mandatory	If you want to require a value for this attribute, select Mandatory. This setting has the following result: For offers, administrators are required to specify a value when the attribute is added to an offer template. The specified value is used for any offers that are based on that template, unless the user specifies a different value when creating or editing the offer. If you change this option after an attribute is in use: If you change from mandatory to non-mandatory, a value is no longer required when the attribute is used. If you change from non-mandatory to mandatory, a value is required whenever this attribute is used in the future. This change has no effect on existing objects unless you edit them. For example, if you open a campaign, target cell spreadsheet, or offer in Edit mode, you are required to specify a value before saving.
