Class Name: OrderDeliveryGroupSummaryBatch¶

Last Updated: 2025-10-22

API Name: OrderDeliveryGroupSummaryBatch Type: Batch/Queueable/Schedulable Test Coverage: Unknown

Business Purpose¶

This batch class anonymizes delivery address information in OrderDeliveryGroupSummary records as part of AANP's GDPR compliance process. When accounts and their associated order summaries are anonymized, this batch ensures that delivery addresses are also properly obscured by replacing actual delivery information with billing city and postal code data, maintaining data privacy while preserving necessary business records.

Class Overview¶

Sharing Model: with sharing
Access Modifier: public
Interfaces Implemented: Database.Batchable, Database.Stateful

Key Responsibilities¶

Identifies OrderDeliveryGroupSummary records requiring anonymization based on related anonymized OrderSummary records
Replaces actual delivery addresses with anonymized data from OrderSummary billing information
Marks delivery group summaries as anonymized to prevent reprocessing
Maintains state across batch execution using Database.Stateful
Processes up to 50,000 OrderSummary records per batch execution

Public Methods¶

start¶

public Database.QueryLocator start(Database.BatchableContext bc)

Purpose: Initializes the batch by identifying OrderDeliveryGroupSummary records that need anonymization based on related anonymized OrderSummary records.

Parameters: - bc (Database.BatchableContext): Batch context provided by the platform

Returns: - Database.QueryLocator: Query locator for OrderDeliveryGroupSummary records to process, or empty query if no records match criteria

Business Logic: - Queries OrderSummary records where Anonymized__c = true and AccountId is NOT in non-anonymized accounts - Limits initial query to 50,000 OrderSummary records - Builds set of qualifying OrderSummary IDs - Returns QueryLocator for OrderDeliveryGroupSummary records where Anonymized__c = false and OrderSummaryId matches the qualifying set - Returns empty result set (WHERE Id = null) if no qualifying OrderSummary records found

execute¶

public void execute(Database.BatchableContext bc, List<OrderDeliveryGroupSummary> scope)

Purpose: Processes each batch of OrderDeliveryGroupSummary records by replacing delivery address fields with anonymized billing data from related OrderSummary records.

Parameters: - bc (Database.BatchableContext): Batch context provided by the platform - scope (List): List of OrderDeliveryGroupSummary records to anonymize

Business Logic: - Extracts OrderSummaryId from each record in scope - Queries related OrderSummary records to retrieve billing city and postal code - For each OrderDeliveryGroupSummary record: - Sets DeliverToCity = OrderSummary.BillingCity - Sets DeliverToStreet = OrderSummary.BillingCity (NOTE: Logic error - should use proper anonymized value) - Sets DeliverToPostalCode = OrderSummary.BillingPostalCode - Sets Anonymized__c = true - Performs DML update with allOrNone = false to allow partial success

finish¶

public void finish(Database.BatchableContext bc)

Purpose: Completes batch execution with minimal logging.

Parameters: - bc (Database.BatchableContext): Batch context provided by the platform

Business Logic: - Outputs debug statement indicating batch completion - No additional processing or error handling

Private/Helper Methods¶

This class contains no private helper methods. All logic is contained within the three required batch interface methods.

Dependencies¶

Apex Classes¶

None - standalone batch class

Salesforce Objects¶

OrderDeliveryGroupSummary: Target object for anonymization (Fields: DeliverToCity, DeliverToPostalCode, DeliverToStreet, Anonymized__c, OrderSummaryId)
OrderSummary: Source for billing data (Fields: BillingCity, BillingPostalCode, Anonymized__c, AccountId)
Account: Used for filtering anonymized accounts (Field: Anonymized__c)

Custom Settings/Metadata¶

None

External Services¶

None

Design Patterns¶

Batch Processing Pattern: Implements Database.Batchable interface for processing large data volumes
Stateful Pattern: Uses Database.Stateful to maintain state across batch chunks (though no instance variables are used)
Two-Stage Query Pattern: Initial query identifies qualifying parent records, then builds scope from related child records

Governor Limits Considerations¶

SOQL Queries: - Start method: 2 queries (1 for OrderSummary, 1 for QueryLocator) - Execute method: 1 query per batch chunk for OrderSummary data - Total: 3 queries per batch chunk

DML Operations: - Execute method: 1 DML statement per batch chunk (updates OrderDeliveryGroupSummary records)

CPU Time: Low - simple field assignments with no complex calculations

Heap Size: - Limited by 50,000 record query in start method - Each batch chunk processes default 200 records unless batch size configured differently

Bulkification: Yes - processes records in batches with bulk DML operations

Async Processing: Yes - runs as asynchronous batch job

Error Handling¶

Strategy: Minimal error handling - Uses Database.update(records, false) to allow partial success - Failed record updates are not logged or reported

Logging: - Only debug statement in finish method - No error logging for failed updates - No tracking of anonymization progress or completion

User Notifications: None - no error notifications or completion alerts

Security Considerations¶

Sharing Rules: Respects sharing rules (with sharing keyword)

Field-Level Security: - No WITH SECURITY_ENFORCED clause used in queries - May bypass FLS restrictions in batch context

CRUD Permissions: - No explicit CRUD permission checks - Relies on running user's permissions

Input Validation: - No validation of billing data before assignment - No null checks on OrderSummary relationship or billing fields - Allows potentially invalid address combinations

Changes & History¶

Initial implementation for GDPR compliance anonymization workflow
Part of broader Account and Order anonymization process

Pre-Go-Live Concerns¶

CRITICAL - Fix Before Go-Live¶

Logic Error on Line 50: DeliverToStreet is set to BillingCity instead of an appropriate anonymized value. This creates invalid address data and may fail validation rules.
No Error Handling: Failed updates are silently ignored with Database.update(records, false). Critical anonymization failures could go undetected, creating compliance gaps.
Missing Null Checks: No validation that related OrderSummary exists or has billing data. NullPointerExceptions could occur if relationships are missing.
Incomplete Anonymization: Only updates three delivery address fields (City, Street, PostalCode). Other address fields (State, Country, etc.) may contain PII and are not anonymized.

HIGH - Address Soon After Go-Live¶

Hard-coded 50,000 Limit: The LIMIT 50000 in start method may not scale with data growth and could leave records unprocessed.
No Validation of Source Data: Does not verify that OrderSummary.Anonymized__c = true before using billing data. Could propagate non-anonymized data.
Missing Monitoring: No logging of records processed, failed, or skipped. Difficult to verify complete anonymization.
Questionable Anonymization Method: Using BillingCity for multiple fields may not provide adequate anonymization. Legal review needed.

MEDIUM - Future Enhancement¶

No Batch Chaining: Batch does not automatically chain to next step in anonymization workflow. Manual scheduling required.
Empty Stateful Implementation: Implements Database.Stateful but maintains no state variables. Unclear why interface is included.
No Rollback Capability: Anonymization is irreversible without proper backup processes documented.
Query Optimization: Could benefit from selective field queries and indexed fields for performance.

LOW - Monitor¶

Minimal Finish Method: Only debug logging provides limited operational insight into batch completion.
No Performance Metrics: Processing time, throughput, and success rates not tracked.
Two-Query Start Pattern: Initial query for OrderSummary could be optimized into single query with subquery.

Maintenance Notes¶

Complexity: Medium Recommended Review Schedule: Quarterly

Key Maintainer Notes: - CRITICAL BUG: Line 50 sets DeliverToStreet = BillingCity. This must be fixed before deployment to production. Consider using a standardized anonymized value or leaving the field blank. - This batch is part of a critical GDPR compliance workflow. Any failures in anonymization create legal liability. - The batch must run AFTER OrderSummary anonymization is complete. Document and enforce this dependency. - Consider implementing comprehensive error handling with Platform Events or Custom Objects to track anonymization progress. - The 50,000 record limit should be reviewed against actual data volumes. Consider implementing batch chaining if limit is regularly exceeded. - Coordinate with legal team to confirm that replacing delivery addresses with billing city/postal code provides adequate anonymization under GDPR. - Test thoroughly with all possible address field combinations and null scenarios. - Consider adding audit trail fields (Anonymized_Date__c, Anonymized_By__c) to support compliance reporting.

Areas that need careful testing when modified: - Relationship chains between OrderDeliveryGroupSummary, OrderSummary, and Account - All address field combinations and null handling - Coordination with other anonymization batches in the workflow - Validation rules on OrderDeliveryGroupSummary that might reject anonymized address data
