An Attribute Set Instance (ASI)<\/strong> represents the actual physical batch of a product. It stores real values like lot number and expiry date, recording what truly exists in inventory. Every traceable stock movement ultimately points to the Attribute Set Instance as the batch-level source of truth.<\/p>\n\n\n\n

Role of Attribute Set Instance in the Overall Flow<\/strong><\/h2>\n\n\n\n

The Attribute Set Instance sits at the execution layer<\/strong> of traceability.<\/p>\n\n\n\n

In the complete lifecycle:<\/p>\n\n\n\n

    \n
  • Attributes describe characteristics<\/li>\n\n\n\n
  • Attribute Sets enforce rules<\/li>\n\n\n\n
  • ASIs store real batch data created during transactions<\/strong><\/li>\n<\/ul>\n\n\n\n

    Without ASIs, traceability remains theoretical.
    With ASIs, traceability becomes operational and auditable.<\/p>\n\n\n\n

    How an Attribute Set Instance Is Created<\/strong><\/h2>\n\n\n\n

    Attribute Set Instances are not created as master data.
    They are created or selected during transactions<\/strong>, exactly when physical stock enters or moves within the system.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    During Material Receipt<\/strong>, the system prompts for Attribute Set Instance creation based on Attribute Set rules:<\/p>\n\n\n\n

      \n
    • Lot number<\/strong> is auto-generated or entered<\/li>\n\n\n\n
    • Expiry (Guarantee) date<\/strong> is entered<\/li>\n\n\n\n
    • Instance-level attributes (such as Flavor) are applied<\/li>\n\n\n\n
    • The Attribute Set Instance is saved along with the received quantity<\/li>\n<\/ul>\n\n\n\n

      Once created, the Attribute Set Instance becomes a permanent identity for that batch.<\/p>\n\n\n\n

      Meaning of \u201cSame Quality Bar\u201d<\/strong><\/h2>\n\n\n\n

      The term same quality bar<\/strong> means that multiple quantities belong to the same ASI<\/strong>.
      This is true only when all attribute values match exactly<\/strong>.<\/p>\n\n\n\n

      A same quality bar requires:<\/p>\n\n\n\n

        \n
      • Same Attribute Set<\/strong><\/li>\n\n\n\n
      • Same Lot number<\/strong><\/li>\n\n\n\n
      • Same Expiry date<\/strong><\/li>\n\n\n\n
      • Same instance-level attribute values (e.g., Flavor)<\/li>\n<\/ul>\n\n\n\n

        If even one value differs, iDempiere treats the stock as a different ASI<\/strong>, even if the product is the same. This rule prevents quality mixing and preserves batch integrity.<\/p>\n\n\n\n

        How Attribute Set Instance Flows Across Transactions<\/strong><\/h2>\n\n\n\n

        Once created, the Attribute Set Instance flows unchanged across all downstream processes. The system never recalculates or modifies Attribute Set Instance data.<\/p>\n\n\n\n

        Across the business flow:<\/p>\n\n\n\n

          \n
        • Inventory movements<\/strong> transfer the same ASI between locators<\/li>\n\n\n\n
        • Customer shipments<\/strong> deduct stock from the exact ASI<\/li>\n\n\n\n
        • Invoices<\/strong> carry ASI details into financial records<\/li>\n\n\n\n
        • Reports<\/strong> show quantity, location, and expiry by ASI<\/li>\n<\/ul>\n\n\n\n
          \"\"<\/figure>\n\n\n\n


          This ensures physical stock, operational documents, and accounting always reference the same batch identity.<\/p>\n\n\n\n

          Attribute Set Instance Traceability and History<\/strong><\/h2>\n\n\n\n

          Each Attribute Set Instance maintains a complete transaction history.
          Lower tabs in the Attribute Set Instance window show how that batch was received, moved, shipped, and invoiced.<\/p>\n\n\n\n

          These views answer critical questions such as:<\/p>\n\n\n\n

            \n
          • Where did this batch come from?<\/li>\n\n\n\n
          • Where is it stored now?<\/li>\n\n\n\n
          • Which customer received it?<\/li>\n\n\n\n
          • Which documents referenced it?<\/li>\n<\/ul>\n\n\n\n

            This makes the Attribute Set Instance a powerful audit and quality-control tool.<\/p>\n\n\n\n

            Purpose<\/strong><\/h2>\n\n\n\n

            The Attribute Set Instance exists to track reality, not assumptions<\/strong>.
            It ensures that every unit of stock can be traced back to its origin and forward to its destination.<\/p>\n\n\n\n

            This is essential for:<\/p>\n\n\n\n

              \n
            • Batch recalls<\/li>\n\n\n\n
            • Expiry-based picking (FEFO)<\/li>\n\n\n\n
            • Quality investigations<\/li>\n\n\n\n
            • Regulatory audits<\/li>\n<\/ul>\n\n\n\n

              Attribute Set Instance-level control is what turns compliance requirements into standard system behavior.<\/p>\n\n\n\n

              Key Capabilities Enabled by Attribute Set Instance<\/strong><\/h2>\n\n\n\n
                \n
              • True batch-level inventory visibility<\/strong><\/li>\n\n\n\n
              • Preservation of quality identity across movements<\/li>\n\n\n\n
              • End-to-end traceability from receipt to customer<\/li>\n\n\n\n
              • Accurate reporting by lot and expiry<\/li>\n\n\n\n
              • Seamless integration with sales and finance<\/li>\n<\/ul>\n\n\n\n

                Outcome<\/strong><\/h2>\n\n\n\n

                With Attribute Set Instances in place, iDempiere delivers:<\/p>\n\n\n\n

                  \n
                • Production-grade batch traceability<\/strong><\/li>\n\n\n\n
                • Accurate stock control by lot and expiry<\/strong><\/li>\n\n\n\n
                • Clean alignment between inventory, operations, and accounting<\/strong><\/li>\n\n\n\n
                • Audit-ready data without manual tracking<\/strong><\/li>\n<\/ul>\n\n\n\n

                  Attribute Set Instance completes the traceability framework by capturing what actually happens on the warehouse floor and carrying that truth across the entire system.<\/p>\n","protected":false},"excerpt":{"rendered":"
