Mapp Engage allows you to create Custom Attributes, but you cannot delete them or change their data type directly in the user interface.
Changing an Attribute’s Data Type
Each attribute can be created in one of several data types: Boolean, Date, String, or Number.
The data type determines how the attribute can be used. For example, numbers cannot be sorted correctly if they are stored as Strings.
If you need to change the data type, Mapp can do this for you on request.
Important
If an attribute contains values that cannot be converted into the new data type, those values will be deleted.
Example: Numbers stored as text can usually be converted into Number format. But if some entries contain non-numeric characters, those values will be lost.
What to do:
Make sure you fully understand the risks of changing an attribute type.
If you are confident it is safe, send a written request to your Account Manager with:
Your Mapp Engage system details
The attribute name
The new data type
If you are unsure, contact your Account Manager to arrange a technical review of your system.
Deleting an Attribute
Attributes cannot be permanently deleted directly in the interface. You can only archive them.
Archiving hides the attribute from the list but keeps it available for segments, imports, and exports.
Permanent deletion removes the attribute and all its stored data. Once deleted, the attribute cannot be used in campaigns, segments, triggers, or whiteboards.
Warning:
If any workflows or processes still rely on the attribute, they will stop working after deletion.
You must be certain that deletion will not cause problems before requesting it.
What to do:
Archive the attribute(s) in the User Interface.
Send a written request to your Account Manager with:
Your Mapp Engage system details
The attribute(s) to be deleted
Note: Mapp will only delete attributes that have first been set to the Archived status.
Backup Before Making Changes
Before deleting or changing any attribute:
Export your contacts from Mapp Engage using a Raw Data Export.
Include the attribute in the export parameters and download the list.
This backup allows you to restore the values if needed.
