Document that Companies and Resources entities do not support
incremental sync in the Autotask API and automatically fall back
to full sync when incremental sync is requested.
This clarifies expected behavior and prevents confusion about why
these entities always perform full syncs even during incremental
sync operations.
Created detailed documentation covering:
- Sync types (Full, Incremental, Sync Selected)
- Date range filtering and entity-specific behaviors
- Database operations (UPSERT, soft deletes)
- Foreign key validation mechanisms
- Performance considerations and optimization tips
- Entity-specific filters and requirements
- Troubleshooting guide and best practices
- Workflow examples and API reference
This complements the existing SYNC_INTERFACE_GUIDE.md with
technical implementation details and behavioral specifications.
