To modify a custom attribute

The steps for modifying custom attributes for a campaign, offer, or cell are the same.

You must have permissions to modify offer and cell custom attributes. For more information, see the Marketing Platform Administrator's Guide.

1.	Select Settings > Campaign Settings.

2.	In the Templates and Customizations section, click Custom Attribute Definitions.

The Custom Attribute Definitions window displays the standard offer attributes and any custom attributes that have already been created.

3.	Click the name of the attribute you want to modify.

4.	Use the Attributes Details window to make changes:

a.	Attribute Display Name: You can change the display name of custom attributes that you created. You cannot change the display name of the standard offer attributes.

b.	Internal Name: You can change the internal name of custom attributes that you created, but any uses of the internal name by existing flowcharts will cause an error, and you will receive a warning when you save the attribute. You cannot change the internal name of the default offer attributes.

Internal names for custom attributes must be globally unique, must start with an alphabetic character, cannot include spaces, and are not case-sensitive.

c.	Optionally, modify the Description.

d.	Check or clear the Mandatory box, depending on whether you want to require a value for this attribute:

If you change from Mandatory to non-mandatory, a value will no longer be required when the attribute is used.

If you change from non-mandatory to Mandatory, a value will be 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 will be required to specify a value before saving.

e.	For a Select Box - String or Text Field - String field, you can modify the Maximum String Length to specify the maximum number of characters to store for any value of this attribute.

Decreasing the length of an existing attribute will truncate existing values, which can adversely affect response tracking if the field is used for matching purposes.

f.	For a Text Field - Numeric or Text Field - Currency field, you can modify the Decimal Places to specify how many decimal places to the right of the decimal point will be displayed.

If you decrease the value, the display will be truncated in the user interface. However, the original value is retained in the database.

g.	If the attribute is a Select Box - String, you can:

Change Allow addition of list items from within edit forms, to allow or disallow users to add new unique values to the list when defining campaigns, offers, or offer templates. This option does not apply to custom cell attributes.

Edit a list item: Select it in the Source list of available values, change it in the New or Selected Item field, and click Accept.

Add a list item: Enter a value in the New or Selected Item field and click Accept.

Remove a list item: Select it in the Source list of available values and click Remove.

Change the Default Value.

Change the Sort Order to determine the order of items in the list.

5.	Click Save Changes.
