Create a request
To start the process, select Data Lifecycle in the left navigation of the Experience Platform UI. The Data lifecycle requests workspace appears. Next, select Create request from the main page in the workspace.
The request creation workflow appears. By default, the Delete record option is selected under the Requested Action section. Leave this option selected.
Select datasets
The next step is to determine whether you want to delete records from a single dataset or all datasets. If this option is not available to you, continue to the Provide identities section of the guide.
Under the Record Details section, use the radio button to select between a specific dataset and all datasets. If you choose Select dataset, proceed to select the database icon (
If you want to delete records from all datasets, select All datasets.
Provide identities
When deleting records, you must provide identity information so the system can determine which records are to be deleted. For any dataset in Experience Platform, records are deleted based on the identity namespace field that is defined by the dataset’s schema.
Like all identity fields in Experience Platform, an identity namespace is composed of two things: a type (sometimes referred to as an identity namespace) and a value. The identity type provides context as to how the field identifies a record (such as an email address). The value represents a record’s specific identity for that type (for example, jdoe@example.com
for the email
identity type). Common fields used as identities include account information, device IDs, and cookie IDs.

If you are deleting records from a single dataset, all the identities you provide must have the same type, since a dataset can only have one identity namespace. If you are deleting from all datasets, you can include multiple identity types since different datasets may have different primary identities.
There are two options to provide identities when deleting records:
