#practice #外部服务采购

📌Key Patterns (click to reveal)
Keyword Answer
Service Master (AC01) Central record for services with number, short text, unit of measure, and valuation
Item Category D Service item — used in PO for external services
Service Entry Sheet (ML81N) Records actual services performed; replaces GR for services
Unplanned Services Services not in the original PO service specification; allowed up to a configured limit
Material Document for Services Posted at service entry sheet acceptance, not at a traditional GR

Question 1 - Creating Service Master Record [recall]

What transaction is used to create a service master record, and what information does it contain?

📌Show Answer
Transaction: AC01 (Create Service Master Record)

Related transactions:

  • AC01 — Create
  • AC02 — Change
  • AC03 — Display

Information contained in a service master record:

  • Service number — Unique identifier for the service
  • Short text / Long text — Description of the service
  • Base unit of measure — How the service is quantified (e.g., hours, days, pieces)
  • Material group — Categorization for the service
  • Valuation — Service category and valuation class for accounting determination
  • Service category — Grouping for reporting and selection

The service master serves as a centralized catalog that can be referenced across multiple purchase orders, ensuring consistency and efficiency in service procurement.

Question 2 - PO Item Category for Services [recall]

What PO item category is used for procuring external services?

📌Show Answer
Item Category D (Service Item) is used for procuring external services.

Key characteristics of item category D:

  • The item does not have a material number (it references service master records instead)
  • A service specification (outline) is maintained at the item level
  • The specification contains individual service lines with quantities and prices
  • No traditional goods receipt — services are confirmed via service entry sheets instead
  • Account assignment is mandatory (services are always consumed directly)
  • Supports both planned services (listed in the specification) and unplanned services (added during entry)
  • The value of the item is the sum of all service lines

Question 3 - Unplanned Services in Service PO [application]

A service PO needs to allow unplanned services up to a maximum of $2,000. How is this configured in the purchase order?

📌Show Answer
Configuration steps for unplanned services:

  1. In the PO item (Item Category D):

    • Create the service specification with the planned service lines
    • Enter the planned services with their quantities and prices

  2. Set the limit for unplanned services:

    • In the PO item detail, specify the limit value of $2,000 for unplanned services
    • This is entered in the “Limits” section of the service item
    • The system uses this as the maximum allowable amount for services NOT listed in the original specification

  3. When creating the service entry sheet:

    • The service provider can enter unplanned services (services not in the original PO specification)
    • The total value of unplanned services cannot exceed the configured $2,000 limit
    • The system validates against this limit and issues warnings/errors if exceeded

  4. Total PO value = Planned services value + Unplanned services limit

This approach provides flexibility while maintaining cost control over service procurement.

Question 4 - Service Entry Sheet Process [recall]

Describe the service entry sheet process and its purpose in external service procurement.

📌Show Answer
Service Entry Sheet (SES) Process:

The service entry sheet replaces the traditional goods receipt for services, since services are intangible and cannot be physically received into a warehouse.

Process steps:

  1. Creation — The service provider or internal person creates a service entry sheet referencing the PO
  2. Service entry — Actual services performed are recorded with quantities and values
    • Planned services from the PO specification are listed
    • Unplanned services can be added (up to the configured limit)
  3. Review — The entry sheet is reviewed for accuracy
  4. Approval/Acceptance — An authorized person accepts (approves) the service entry sheet
    • This triggers the material document posting (and accounting document if applicable)
    • Acceptance can be a single-step or multi-step process depending on configuration
  5. Invoice verification — The vendor invoice is verified against the accepted service entry sheet

Purpose:

  • Confirms that services were actually performed
  • Provides the basis for vendor payment
  • Creates the equivalent of a goods receipt for financial posting
  • Enables tracking and approval of service costs before payment

Question 5 - External Service vs Material Procurement Comparison [analysis]

Compare external service procurement with standard material procurement. What are the key differences in PO structure, goods receipt process, and invoice verification?

📌Show Answer
Key Differences:
Aspect Material Procurement Service Procurement
PO Item Category Standard (blank) or consignment Item Category D (Service)
Material Reference Material master record Service master record (AC01)
PO Structure Item-level quantity and price Service specification with multiple service lines at item level
Goods Receipt Physical GR via MIGO (movement type 101) Service Entry Sheet via ML81N (no physical GR)
GR Document Material document + Accounting document Material document posted at SES acceptance
Unplanned Items Generally not supported (PO defines items) Unplanned services allowed with limit
Quantity Tracking Tracked in inventory (if stock material) No inventory tracking; direct consumption
Account Assignment Optional (for stock) or mandatory (for consumables) Always mandatory — services are always consumed
Delivery Physical delivery to warehouse or point of use No physical delivery; service performance confirmed
Invoice Reference PO and GR document PO and Service Entry Sheet
Valuation Based on material valuation Based on service line prices in specification

Summary: The fundamental difference is that material procurement deals with tangible goods tracked in inventory, while service procurement manages intangible deliverables confirmed through service entry sheets. The PO structure for services is more complex (multi-line specification) to accommodate the detailed breakdown of service activities.

Question 6 - Service Entry Sheet Transaction [recall]

What transaction is used to create and manage service entry sheets?

📌Show Answer
Transaction ML81N — Service Entry Sheet (centralized transaction)

Related transactions:

  • ML81N — Integrated service entry sheet (create, change, display, accept)
  • ML81 — Create service entry sheet (older version)

Key functions in ML81N:

  • Create new service entry sheets referencing a PO
  • Enter actual service quantities performed
  • Add unplanned services (if allowed by the PO)
  • Submit for approval
  • Accept (approve) service entry sheets
  • Display and review existing entry sheets
  • The transaction supports the full lifecycle from creation through acceptance

Question 7 - Service Entry Sheet with Planned and Unplanned Services [application]

A service PO contains 3 planned services and allows unplanned services. Describe the steps to create, complete, and accept a service entry sheet for this PO.

📌Show Answer
Steps to complete and accept the service entry sheet:

Step 1: Create Service Entry Sheet (ML81N)

  • Enter the PO number as reference
  • The system automatically loads the 3 planned service lines from the PO specification

Step 2: Enter Actual Quantities for Planned Services

  • For each of the 3 planned service lines, enter the actual quantity performed
  • The system calculates the value based on the agreed prices in the PO
  • Example:
    • Service 1: Planned 100 hours → Actual 95 hours
    • Service 2: Planned 50 units → Actual 50 units
    • Service 3: Planned 10 days → Actual 12 days

Step 3: Add Unplanned Services (if needed)

  • Navigate to the unplanned services section
  • Enter additional services not in the original specification
  • Provide description, quantity, unit, and price for each unplanned service
  • The system checks the total against the configured limit

Step 4: Review and Save

  • Review all entries for accuracy
  • Save the service entry sheet (status: “In Preparation” or “Submitted”)

Step 5: Accept (Approve)

  • An authorized approver opens the entry sheet
  • Reviews the services and values
  • Clicks “Accept” to approve
  • System automatically posts the material document upon acceptance
  • If account assignment is valuated, an accounting document is also posted

Step 6: Invoice Verification

  • The vendor submits an invoice
  • Reference the PO and/or service entry sheet number
  • The system matches invoice against the accepted service entry sheet

Question 8 - Material Document Posting in Service Procurement [analysis]

At what point does the material document get posted in service procurement? Why is this different from the material goods receipt process?

📌Show Answer
When the material document is posted:
The material document is posted at the moment of service entry sheet acceptance (approval), not at the time of creation.

Why this differs from material GR:

  1. No physical goods to receive:

    • In material procurement, goods physically arrive and the GR is recorded immediately (MIGO)
    • Services are intangible — there is no physical delivery event to trigger receipt

  2. Service confirmation requires validation:

    • The service entry sheet first needs to be created (describing what was performed)
    • Then it must be reviewed and formally accepted by an authorized person
    • Only upon acceptance is the posting triggered — this ensures proper authorization before financial commitment

  3. Approval workflow:

    • Material GR can often be posted by warehouse staff upon delivery
    • Service entry sheets require explicit acceptance, which may involve multiple approval levels
    • This additional step provides financial control over service costs

  4. Posting logic:

    • At SES acceptance: Material document is posted (recording the service “receipt”)
    • If valuated: Accounting document also posted (charging the cost object, crediting GR/IR)
    • At invoice: GR/IR clearing is debited, vendor is credited

In summary: The posting occurs at SES acceptance rather than at a traditional GR because services require formal confirmation and approval of performance before financial recognition, unlike physical goods which are immediately verifiable upon delivery.
