    "name": {
        "familyName": "TryAddClaims",

    },
    "userName": "rest11@test.com",

        "organization": "rest_organization",
        "inn": "inn"
    }
}

response:

{
    "emails": [
        {
            "type": "home",
            "value": "rest11@test.com"
        },
        "rest11@test.com"
    ],
    "meta": {
        "created": "2022-09-12T07:43:20.474255Z",
        "location": "my-host/scim2/Users/1d64942c-ce24-48cf-ad47-665f4f9c37f8",
        "lastModified": "2022-09-12T07:43:20.474255Z",
        "resourceType": "User"
    },
    "schemas": [
        "urn:ietf:params:scim:schemas:core:2.0:User",
        "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User"
    ],
    "roles": [
        {
            "type": "default",
            "value": "Internal/everyone"
        },
        {
            "display": "everyone"
        }
    ],
    "name": {
        "givenName": "rest11@test.com",
        "familyName": "TryAddClaims"
    },
    "id": "1d64942c-ce24-48cf-ad47-665f4f9c37f8",
    "userName": "rest11@test.com",
    "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User": {
        "organization": "rest_organization"
    }
}

why inn not present in the response, but organization with same config is present? In wso2 admin panel inn also empty for this user.
