With TraceLink’s OPUS Platform and B2N Integrate-Once™ architecture, this transaction works in conjunction with Enterprise Serialization Management (ESM) systems and enables secure, standards-based updates to EPCIS 1.2-compliant serialization records, ensuring that all trading partners and systems reference the most current and accurate lot information. ### Key Use Cases - Correct or update lot-level attributes (e.g., expiration date, GTIN, or batch number) for serialized products. - Ensure accurate lot data is available for risk evaluation and product release. - Maintain regulatory compliance by updating DSCSA and global track and trace product information. - Synchronize serialization data across internal systems and external trading partners. - Support downstream verification, traceability, and product recall readiness. - Enable real-time updates without reissuing full EPCIS event history. ### Data Elements Included An EPCIS 1.2 – SOM ESM Update Lot Information transaction includes: - **Transaction Type:** SOM ESM Update Lot Information. - **Lot Number:** Unique identifier for the batch or lot being updated. - **Updated Attributes:** GTIN, expiration date, manufacturing date, or other product metadata. - **Associated EPCs:** Serialized product identifiers (SGTINs) linked to the lot. - **Business Location:** Facility or region where the update originates. - **Timestamp:** Date and time the update was submitted. - **Reason Code or Comments:** Explanation for the update (e.g., correction, regulatory requirement). - **Digital Signature (optional):** For secure, auditable confirmation. - **Sender/Receiver Identifiers:** GLNs or partner codes for traceability. ### Benefits of EPCIS 1.2 – SOM ESM Update Lot Information - Ensures data accuracy across serialization, and regulatory systems. - Enables real-time updates to lot-level information without reprocessing full shipments. - Supports DSCSA and global track and trace compliance by maintaining accurate product metadata. - Improves inventory and shipment decision-making with the most up-to-date lot attributes. - Enhances traceability and verification by aligning EPCIS records with current lot data. ### How TraceLink Supports EPCIS 1.2 SOM ESM Update Lot Information TraceLink’s OPUS Platform, powered by B2N Integrate-Once™, enables secure, compliant, and efficient lot data updates by: - Centralizes lot data updates by integrating with master data, serialization, and compliance systems. - Synchronizes updated lot attributes (e.g., GTIN, expiration date, batch number) across all connected partners and internal platforms. - Validates lot-level changes before applying updates to ensure data integrity and regulatory compliance. - Distributes real-time updates to downstream systems without requiring reprocessing of full EPCIS event files. - Maintains a full audit trail of all lot modifications for traceability, compliance, and quality control. - Supports global partner alignment by ensuring consistent lot data across all serialization workflows. ### Explore More Serialization & Compliance Capabilities - [**EPCIS Serialization**](/orchestration-integration-transactions/accelerate-digital-supply-chain-collboration-with-b2b-integration/epcis-12-serialization): Record and share commissioning events at unit, case, or pallet level for regulatory compliance. - [**SOM End of Batch**](/orchestration-integration-transactions/accelerate-digital-supply-chain-collboration-with-b2b-integration/epcis-12-som-end-batch): Close a serialized batch and validate lot data before downstream use. - [**DSCSA ASN**](/orchestration-integration-transactions/accelerate-digital-supply-chain-collboration-with-b2b-integration/epcis-12-dscsa-advance-ship-notice): Share serialized shipment data with downstream partners. - [**SOM Product Release**](/orchestration-integration-transactions/accelerate-digital-supply-chain-collboration-with-b2b-integration/tl-xml-som-product-release): Authorize serialized units for shipment, requiring validated lot details. - [**SOM Receipt**](/orchestration-integration-transactions/accelerate-digital-supply-chain-collboration-with-b2b-integration/tl-xml-som-receipt): Confirm receipt of serialized shipments.
