To modify a custom attribute

You modify campaign, offer, and cell custom attributes in the same way.

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.

The Campaign Settings page opens, presenting links for various administration tasks.

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

The Custom Attribute Definitions window opens. The default custom offer attributes and any previously created custom attributes are listed.

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

The Attributes Details window opens.

4.	Modify data for the custom attribute as follows:

a.	If you are modifying a custom attribute that you created, you can edit the Attribute Display Name. If you are modifying one of the standard custom attributes, you cannot edit this field.

If you are modifying a custom attribute that you created, you can edit the Internal Name. However, be aware that any uses of the internal name by existing flowcharts will cause an error, and you will receive a warning when you save the attribute. If you are modifying one of the default custom attributes, you cannot edit this field.

Custom attribute internal names must be globally unique and are case-insensitive. They have specific character restrictions and must start with an alphabetic character. For details, see About special characters.

c.	Optionally, modify the Description.

d.	If the attribute is a Select Box - String or Text Field - String field, you can modify the Maximum String Length. This specifies the maximum number of characters that will be stored for any value of this custom attribute.

If you decrease the Maximum String Length of a String field when modifying an attribute, you receive a warning that existing data may be truncated. Decreasing the length of an existing custom attribute will truncate any data values longer than the new length, which can adversely affect response tracking if the field is used for matching purposes.

e.	If the attribute is a Text Field - Numeric or Text Field - Currency, you can modify the Decimal Places. This specifies the number of decimal places to the right of the decimal point that are displayed. For example, for currency, you may want to specify a decimal place value of two to show cents.

If you decrease the Decimal Places number when modifying an attribute, if the attribute is used by offers or cells, the value for the attribute for those offers or cells as displayed through the web-based GUI is truncated to the new number of decimal places allowed. However, the value with the original number of decimal places is retained in the database.

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

Change the setting for Allow addition of list items from within edit forms.

Modify list items.

You can only add or remove list items if the attribute was originally created with the Allow addition of list items from within edit forms option selected.

Add list items by entering values in the New or Selected Item field and clicking Accept.

Remove list items by selecting one or more items in the Source list of available values and clicking Remove.

Edit an existing list item by selecting it in the Source list of available values. The item displays in the New or Selected Item field, where you can edit it and then click Accept.

5.	When you have finished making your modifications, click Save Changes.
