Shared component inventory across competing bundles
Last updated: 2026-07-31
Written and reviewed by Seller Profit Guard Editorial Team.
A declared plan allocates 60 of 140 shared units to 30 Bundle X units. Eighty shared units remain. Bundle Y also has 80 usable unique units and requires one of each, so it can support 80 units. This is one ordered allocation—not proof that the mix maximizes margin, demand coverage, or service.
Reconcile shared pool
160 minus 10 reserved minus 10 unreflected commitments equals 140. The competing-bundle workpaper records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a traceable Scenario B allocation.
Use one state. At checkpoint 1, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.
Calculate independent X capacity
At two shared units each, X independently supports 70. The competing-bundle workpaper records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a traceable Scenario B allocation.
This is a feasibility ceiling. At checkpoint 2, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.
Apply priority X plan
Thirty X units consume 60 shared units. The competing-bundle workpaper records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a traceable Scenario B allocation.
Record the owner. At checkpoint 3, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.
Calculate remaining shared
140 minus 60 leaves 80. The competing-bundle workpaper records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a traceable Scenario B allocation.
Negative results review. At checkpoint 4, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.
Reconcile unique Y
90 minus 5 minus 5 leaves 80. The competing-bundle workpaper records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a traceable Scenario B allocation.
One per Y supports 80. At checkpoint 5, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.
Calculate Y shared capacity
Eighty shared units at one each support 80 Y. The competing-bundle workpaper records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a traceable Scenario B allocation.
Round down. At checkpoint 6, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.
Select Y minimum
Minimum shared and unique capacities equals 80. The competing-bundle workpaper records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a traceable Scenario B allocation.
Both are tied. At checkpoint 7, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.
Test alternative priority
Increasing X by one reduces shared Y capacity by two. The competing-bundle workpaper records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a traceable Scenario B allocation.
Mix changes are nonlinear. At checkpoint 8, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.
Reject optimality claim
One sequence does not maximize margin or demand coverage. The competing-bundle workpaper records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a traceable Scenario B allocation.
Use a separate optimization model. At checkpoint 9, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.
Preserve allocation evidence
Record reason, approver, order horizon, and rollback. The competing-bundle workpaper records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a traceable Scenario B allocation.
Priority is reversible. At checkpoint 10, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.

Public private data is prohibited. Apply it while keeping Available, additional reservations, unreflected commitments, recipes, fixed capacity, competing allocation, thresholds, and operational authority separate.
Reconcile shared pool: component lab 1
Recalculate the relevant outputs from both fixtures. 160 minus 10 reserved minus 10 unreflected commitments equals 140. Change one input only, preserve the remaining inventory-state and recipe assumptions, and record allocatable units, component quotients, maximum bundles, tied bottlenecks, shared consumption, remaining capacity, and status.

Evidence boundary for a traceable Scenario B allocation
The fixed-bundle fixture uses three compatible components at one location. After additional reservations and commitments, A has 100 allocatable units and requires two, B has 70 and requires one, and C has 200 and requires four. Capacities are 50, 70, and 50, so maximum complete bundles equal 50 and A plus C are tied bottlenecks. The result is 10 bundles above the default 40-bundle control. The competing-bundle fixture starts with 140 allocatable shared units. Thirty priority Bundle X units consume 60 shared units because X requires two each, or 42.86 percent of the shared pool. The remaining 80 shared units and 80 allocatable unique-Y units each support 80 Bundle Y units, creating a tied bottleneck. The allocation stays 17.14 percentage points below the default 60 percent priority-utilization ceiling, and both 60-day evidence windows are 15 days above the default 45-day evidence floor.
The packet demonstrates entered complete-set arithmetic and one priority allocation under a dated policy. It cannot prove demand, optimal mix, compatible future receipts, correct safety stock, purchase quantity, fulfillment eligibility, accounting treatment, customer outcome, or the correct business action.
Release, monitor, and restore the competing-bundle workpaper
Block non-finite or invalid quantities, recipes, dates, confirmations, scope, compatibility, privacy, copied scenarios, or conflicts, and mask every derived output. Review insufficient evidence, overcommitment, infeasible priority, excessive shared-component utilization, or capacity below threshold. Ready clears only the entered worksheet.
Before indexing or operational use, preserve evidence and rollback artifacts; run typecheck, unit, integration, build, content, similarity, SEO, image, link, mobile, strict-route, deployment, and live checks; then compare actual component consumption without claiming same-period causality.
