The flowchart illustrates the Break-Down Maintenance Order process for Internal/External Service within an SAP system, covering integrated modules like PM (Plant Maintenance), MM (Materials Management), and FICO (Financial Accounting & Controlling). Below is a detailed breakdown of the flowchart’s steps:

🛠️ Plant Maintenance (PM) Activities

• Create Malfunction Notification (Transaction Code: IW21): A malfunction notification is created to document the breakdown.
• Analyze the Break-Down Issue & Update Mal-fun Start Date: The maintenance team analyzes the breakdown and updates the malfunction start date.
• Attend the Machine & Check the Break-Down Condition: Technicians physically inspect the machine to assess the breakdown condition.
• If Any Services Required? (Yes/No): A decision is made on whether services are needed:
  • Yes: Proceed to create a break-down maintenance order.
  • No: If no services are required, the notification downtime is updated, and the notification is closed.
• Create Break-Down Maintenance Order (Transaction Code: IW31): A break-down maintenance order is created based on the analysis.
• Assign Work Permits if Required: If necessary, work permits are assigned to the maintenance order.
• Plan Services for Break-Down Order: Planning for the required services begins.
• If Internal/External? (Yes/No): A decision is made on whether the service will be internal or external:
  • Yes (Internal): A Confirmation Number for Internal Services is generated.
  • No (External): A Purchase Requisition for External Service is created.
• Time Confirmation for Operations (Transaction: IW41): Work time is recorded and confirmed for task completion.
• Update the Malfunction End Date (TECHO) for Order: The malfunction end date is updated, marking the technical completion of the order.

📦 Materials Management (MM) Actions

• Create PO against External Service PR (Transaction Code: ME21N): A purchase order is created based on the purchase requisition for external services.
• Service Entry Sheet (Transaction Code: ML81N): A service entry sheet is created to record the services provided by the external vendor.

💰 Finance/Controlling (FICO) Steps

• Invoice Verification (Transaction: MIRO): Process vendor invoices for services provided.
• Business Completion for Order: Finalize the order from a business perspective.
• Settlement for Order (Transaction: KO88): Settle costs associated with the maintenance order.

🔗 Key Integration Points:

• PM to MM: Service requirements trigger purchase requisition and order processes for external services.
• MM to FICO: Service entries and purchases initiate financial transactions.
• PM to FICO: Completed maintenance orders are settled in the controlling module.
