SAI / 01Purchase vs. transfer planning
Decide where inventory should come from.
A replenishment requirement is only half the answer. SOBERAN checks internal availability before purchasing and creates a traceable recommendation for the right source mix.

02 / The sourcing decision
Buying is not the default when the network already holds stock.
The source decision should happen after the requirement is calculated and before the order is created. That sequence reveals internal inventory, reduces avoidable purchase proposals, and gives the planner one place to approve the final mix.
03 / Operating flow
A decision gate before every purchase proposal
- 01
Calculate net requirement
Start with consumption, coverage, safety stock, current stock, pending customer orders, and in-transit inventory.
- 02
Check safe internal surplus
Search other warehouses for the same SKU and identify only the quantity that can move safely.
- 03
Build the source mix
Recommend a transfer, a purchase, or a split with quantities assigned to each source.
- 04
Record the execution
Preserve the original recommendation, approval, edits, outbound request, ERP response, document number, owner, and timestamp.
04 / Decision logic
The buy-or-move decision, made explicit
Every branch ends in an action the planner can review and the ERP can execute.
05 / Evidence
From recommendation to ERP document
For Sumatec, approved recommendations become grouped purchase orders and warehouse transfers in the ERP. The system retains the recommendation, planner edits, response, document number, responsible person, and submission time.

Questions for evaluating fit.
When should inventory be transferred instead of purchased?
A transfer is appropriate when another warehouse has enough safe surplus to cover some or all of the destination requirement without putting its own service level at risk.
What is a split replenishment recommendation?
It assigns part of the required quantity to one or more internal warehouse transfers and leaves the remaining quantity for an external purchase.
Can planners override the recommendation?
Yes. The operating workflow supports review and manual adjustments while preserving the original recommendation, approval state, responsible person, timestamps, and ERP response.
