PS 202 · EXECUTE
How does PS connect work, materials, and external services?
Combine confirmations, activity allocation, material components, reservations, requisitions, project stock, direct procurement, external processing, and services.
READ THE CAPABILITY
Connect project work to the supply path that can execute it
PS can collect internal work, material demand, external processing, and services against project structures or their executable activities. The assignment determines where the commitment, receipt, confirmation, consumption, and cost evidence belong.
The project object does not replace purchasing, inventory, or service controls. It provides the accountable work boundary that lets those disciplines explain why the requirement exists and how its cost contributes to delivery.
WORKING FLOW
From business decision to controlled evidence
Follow the capability through the records and decisions that make the result explainable.
Define the requirement
Translate the activity or WBS scope into material, internal-capacity, external-processing, or service demand.
Choose the supply route
Select project stock, reservation, requisition, purchase order, internal activity, or approved service path.
Receive and consume
Record goods receipt, service acceptance, confirmation, issue, or other execution evidence against the accountable object.
Reconcile the result
Compare requirement, commitment, delivery, actual cost, remaining need, and project forecast before closure.
DIAGNOSTIC EVIDENCE
What should be traceable?
When the result looks wrong, start with the last trusted record and follow the owning boundary.
WBS or activity assignment, component, service scope, quantity, required date, and responsible owner.
Reservation or requisition, purchase order, supplier, account assignment, project stock, and delivery status.
Goods receipt, service acceptance, confirmation, material issue, invoice, actual cost, and remaining balance.
SCENARIO
A project needs a specialist service and controlled material
The material is reserved and issued to the accountable work package while the specialist work follows an external-service purchase path. Receipt and acceptance remain separate evidence, so the project can distinguish delivered material, performed service, and invoiced cost.
- Business rule and accountable owner are explicit
- SAP object and source evidence remain connected
- Exception or outcome is reconciled before closure
CORE MODEL
Three questions to resolve
A sound design makes ownership, control, and evidence explicit before configuration.
Internal resources and confirmations
Define the rule, responsible object, required master data, resulting document or posting, and proof.
