enableNestedPartialOverride option

Learn about the enableNestedPartialOverride option for updating an entity.

The enableNestedPartialOverride option works only when you update an entity using the partial override option in the Entities. For more information, see topic Partial overrides.

You may have difficulties with doing updates for nested attributes because you are unable to do partial overrides for specific nested attributes values from any particular source system. For example, if Source System A has previously loaded 10 phone numbers and as part of the single update request, this source system wants to update one of the 10 phone numbers and add a new one. Currently, there is no way for you to do this without a full reload of 10 phone numbers plus one new phone number for Source System A. If you use the partial override bypassing two phone numbers, this is one to update and another to add, Then, as per the current behavior, the existing 10 phones numbers are wiped out, and two new phones numbers are added to the profile.

Note: Partial override of nested attributes is only for the first level of sub-nested attributes.

To append a row for some existing nested attributes, a new parameter is available on the physical configuration level enableNestedPartialOverride. This parameter changes the current default behavior instead of wiping out existing nested values and will start appending new nested values for a partial override.

You should set this option on a tenant physical configuration level and accept true/false as possible values; for example:

{
  "tenantId": "YourTenantId",
   ...
  "enableNestedPartialOverride": true
}

Use Cases

Note: Where appropriate, changed values are underlined in the examples.

This is an example of a Nested attribute phone:

Table 1. Example: Nested Attribute Phone
Name	Phone Type	Phone Country	Phone Number
John Smith	Business	USA	347-534-8234
John Smith	Home	USA	244-344-5931
John Smith	Personal	USA	513-879-4208

Append

The following is an example of adding a row to the nested attribute phone. There, you must set up enableNestedPartialOverride in the physical configuration.

POST /entities?options=partialOverride
BODY

Table 2. Example: Adding a Row to Nested Attribute
Name	Phone Type	Phone Country	Phone Number
John Smith	Travel	USA	347-534-8234

The result should be:

Table 3. Example: Result of Adding a Row to Nested Attribute
Name	Phone Type	Phone Country	Phone Number
John Smith	Business	USA	347-534-8234
John Smith	Home	USA	244-344-5931
John Smith	Personal	USA	513-879-4208
John Smith	Travel	USA	347-534-8234

Update

Case 1

Update an existing row in your nested attribute.

First, you need to set up enableNestedPartialOverride in the physical configuration, and then you need to setup keyAttributeURIs in the business configuration:

          "keyAttributeURIs": [
            "configuration/entityTypes/Person/attributes/Phone/attributes/Name",
            "configuration/entityTypes/Person/attributes/Phone/attributes/PhoneType"
          ]

POST /entities?options=partialOverride with nested URI
BODY

Table 4. Example: Updating an Existing Row in Nested Attribute
Name	Phone Type	Phone Country	Phone Number
John Smith	Business	Germany	555-555-5555

In this case, an exact row with two fields for Name and Phone Type are located and updated, as shown in this example:

Table 5. Example: Updated Fields for an Existing Row in Nested Attribute
Name	Phone Type	Phone Country	Phone Number
John Smith	Business	Germany	555-555-5555
John Smith	Home	USA	244-344-5931
John Smith	Personal	USA	513-879-4208

Case 2

You can create a hidden attribute to use it as a primary key and manage its values.

Table 6. Example: Creating Hidden Attribute to Use as Primary Key
ID	Name	Phone Type	Phone Country	Phone Number
1	John Smith	Business	USA	347-534-8234
2	John Smith	Home	USA	244-344-5931
3	John Smith	Personal	USA	513-879-4208

This is an example for keyAttributeURIs:


          "keyAttributeURIs": [
            "configuration/entityTypes/Person/attributes/Phone/attributes/ID"
          ]

POST /entities?options=partialOverride with nested URI
BODY

Table 7. Example: Hidden Attribute Created to Use as Primary Key
ID	Name	Phone Type	Phone Country	Phone Number
2	John A Smith	Home Mobile	USA	777-777-7777

In this case, there is an exact row by ID for which an update can be made, as shown in the following:

Table 8. Example: Updated Exact Row by ID
ID	Name	Phone Type	Phone Country	Phone Number
1	John Smith	Business	USA	347-534-8234
2	John A Smith	Home Mobile	USA	777-777-7777
3	John Smith	Personal	USA	513-879-4208

Full Row Update

POST /entities?options=partialOverride&preserveURIs
BODY

BODY is with a URI such as "entities/0001L5U/attributes/Person/1n5QlE/Phone/9Bkdgy", which points to the first row.

Table 9. Example: Row to Create for Updating Full Row
Name	Phone Type	Phone Country	Phone Number
John A Smith	Business Mobile	Germany	999-999-9999

These results replace all values in the selected row by URI.

Table 10. Example: Updated Full Row
Name	Phone Type	Phone Country	Phone Number
John A Smith	Business Mobile	Germany	999-999-9999
John Smith	Home	USA	244-344-5931
John Smith	Personal	USA	513-879-4208

Table 11. Parameters
Parameter	Default	Description
`enableNestedPartialOverride`	`False` (null)	If set to `true`, turn ON the append logic for a partial override of nested values.

Important: This option works only in the case of updating an entity together with using the partialOverride option in the Rest API request.

Common Behavior

When the parameter enableNestedPartialOverride is true and you execute a partial override, then input nested attribute values are added to existing values (old values are not removed). As a result, nested attributes will have all values which they previously had before the update plus values which were passed as inputs.

Examples

Existing Entity

An entity with some nested attribute, for example, entity type HCP with the nested attribute License.

`preserveURIs`

You can use enableNestedPartialOverride=true logic with the preserveURIs option.

In the request (with the partialOverride option), if you include the preserveURIs option and set the uri of the nested attribute and its sub-attribute, then a partial override is performed of this nested attribute by its uri.

Example

Individual entity with two AlternateName nested attributes values.

The second nested attribute value is updated, as follows:

change only some specific sub-attributes of the nested attribute, for example, the value of the LastName sub-attribute,
do not change another attribute but send it at the request, for example, the value of the FirstName sub-attribute,
do not change anther attribute in any way, and you do not send it at the request, for example, the value of the Type sub-attribute,

For the example above, these changes occur:

the value of the sub-attribute LastName is overwritten and an update occurs at the singleAttributeUpdateDates section for the proper crosswalk.
the value of sub-attribute FirstName is NOT changed, but an update occurs at the singleAttributeUpdateDates section for the proper crosswalk (similar to the behavior when enableNestedPartialOverride=false).
the value of the sub-attribute Type is NOT changed in any way.

At the update request, if you do not set uris of nested values, as shown in the following example:

Overwrite With the partialOverride and preserveURIs Optionss

    ]
  }
]

Then, you will see three nested values, because the uri of sub-attributes without the uri of nested values are ignored, as shown in the following example:

Reference Entity

Note: Currently, refRelation attributes are affected by the append logic of enableNestedPartialOverride from requests in the /entities endpoint.

The current behavior can be shown via the following case:

When two entities are created that are related by relation (HCP, Location, HasAddress).

HCP has the reference attribute Address with nested sub-attribute Phone, which is an attribute of the relation type HasAddress.
