Electronic components: connect NetSuite and Postgres revision-aware stock allocation

What this looks like in electrical and electronic components

An electronics business stocks two revisions of a component under related internal references. One customer assembly can use either revision, while another requires a specific approved version. A Postgres planning application currently aggregates the entire item family and marks both orders covered. The useful integration preserves the eligibility relationship and allocated quantity for each demand line. Planners can then see an actual shortage on the restricted order without treating unrelated stock as available or moving an existing allocation from another customer silently.

Records, ownership, and update rules

Work through the process

1. 01
   Define the eligibility question

   Select one assembly family and identify the approved component relationships it depends on. Have engineering explain whether revision and manufacturer restrictions apply. Avoid building an allocation rule from description similarity or an unreviewed catalog substitution.
2. 02
   Preserve the source identities

   Keep NetSuite record references separate from generated Postgres keys and engineering identifiers. Review existing cross-references before backfill. A shared SKU string may be insufficient when the business distinguishes manufacturer part and revision elsewhere.
3. 03
   Model allocation as a relationship

   Store which supply quantity covers each demand line, including units and applicable conditions. Reconcile allocation totals to available eligible stock. Do not repeat the full stock quantity for every joined demand row or count the same inventory twice.
4. 04
   Expose proposals separately from commitments

   A planning application can suggest a different allocation, but accepted changes must follow the responsible owner’s process. Preserve the current commitment while the proposal is reviewed. Any ERP update requires a verified operation and accepted destination response.
5. 05
   Test restricted and late-change cases

   Use two orders with different approved applicability and one component revision change. Confirm that the correct order becomes constrained. Then replay updates and reconcile the totals so the view remains stable after interruptions.

Handle the exceptions explicitly

A substitute is stocked but not approved

Show it as a candidate for engineering review, outside eligible coverage.

One supply quantity is proposed for two orders

Expose the conflict to planning and retain one accepted allocation rather than independently satisfying both demands.

A component reference is corrected

Review its affected relationships and preserve the correction history; do not reassign historical shipments by assumption.

What to verify before expanding

• Restricted demand cannot consume stock that lacks approved applicability.
• Accepted allocation totals do not exceed eligible supply in the same unit.
• Proposed reallocations remain separate from current commitments.
• The user can trace a readiness result to component identity and approval evidence.
