This is used to help in making collaborative forecasts and agreements.

SC coordination

This component in Supply Chain is used to coordinate the exchange of data and information between different business units.

Q6. What are the key benefits of using Supply Chain process in an organization?

Ans: Organizations can achieve following benefits in a distributed environment −

To reduce accounts receivable collections with better visibility into the AR process, aging and extension of credit, and help to reduce day’s sales outstanding using SCM process.
To effectively manage forecasting and handling sudden changes in demand and supply process.
To effectively use Net Fixed assets NFA like plants and equipment.
To meet customer demands, you can smartly plan and manage Supply chain Management process in an organization.
Proper inventory optimization, order fulfillment and shipping of the goods.
Distribution of the key information to all the stake holders spread across the network.
Improved communication and collaboration between different business lines to manage demand and supply process in an organization.
To improve production efficiency and reduction in production quality issues and hence reduce cost of goods sold.
To reduce transportation duties and taxes, and increase rebates and incentives. It also helps to reduce transportation errors.

Q7. Explain demand planning and management process you have handled as part of Supply Chain?

Ans: Demand management is used to forecast, manage and plan the demands of goods and has defined set of processes and capabilities to produce goods. This component is used to improve the demand planning by utilizing promotions.

Based on historical sales data, you can handle demand for every store, product from different customers and hence you can see customer responses as per change in pricing policies, and profit for a particular product in the organization.

You use demand models to predict consumers’ reaction with price change. As per organization goals like - increase profit, revenue, etc. you can define selling strategies for the products.

Q8. What is PIR Planned Independent Requirement?

Ans: Demand management is performed by Planned Independent requirement PIR. Planned Independent requirement provides input for production planning. A PIR contains one planned quantity of product and one date for material or a Planned Quantity is split over a span of time period.

Q9. What is MTS and MTO Planning strategy under Supply Chain?

Ans: Make to Stock Planning strategy (MTS)

This is planning strategy where stock is produced without sales order. It is used to meet customer demands in future.

Make to Order planning strategy (MTO)

In this planning strategy, finish products are not produced until you receive sales order from a customer. For MRP run, you only consider Sales order.

In MTO strategy, you only produce sales order stock and products are delivered as per sales orders from specific customer.

Q10. What is Planning strategy you select to perform MTS and MTO?

Ans: When you use Planning strategy 10, only PIR quantity is considered for MRP run and sales order are completely ignored. In this PIR requirement type LSF and is reduced when you deliver stock to customer.

When you use Planning strategy 40, for MRP run maximum of 2 PIR and Sales order can be considered and PIR is reduced when enter the Sales order. PIR requirement type is VSF in this case.

You use Planning strategy 20 for make to order MTO process and planning strategy 25 is used to produce product variants when there is request for variant products from customer.

Q11. What is the use of MRP run or planning run?

Ans: MRP run or planning run is an engine which is used to fill demand and supply gap. Issues & Receipts are called MRP Elements. Issues include PIRs, Dependent Requirements, Order Reservations, Sales Orders, Issuing Stock Transfer Orders, etc. and receipts include Production Orders, Purchase Requisitions, Purchase Orders, Open Production Orders, Receiving Stock Transfer Order, Schedule lines, etc.

Q12. What are the different types of MRP run?

Ans: NetChange

In this run system consider those material which has undergone some changes from the previous MRP run.

NetChange in planning horizon

This run considers the requirement in predefined planning horizon and not like net change which check the future requirements.

In this run, system consider only those material which has undergone some changes from their last MRP run.

Regenerative Planning

In this run, system consider all the material irrespective of changes and it is time consuming and not common in Production planning.

Q13. Explain the difference between basic scheduling and lead time scheduling?

Ans: Basic Scheduling

It only calculates basic dates for orders in MRP run and in house production time for material master in use.

Lead time Scheduling

In this MRP, production dates are defined by lead time scheduling for planned orders.

Q14. What is Bill Of material master data and what information it contains?

Ans: Bills of material master data is related to material requirement planning and provides the list of components to produce the product.

Q15. What is the use of super BOM?

Ans: To produce a product with different variants, you can create super Bills of Material that has list of components to manufacture different variants of a product and selection of component depends on details mentioned in planning order. You can create up to 99 Bills of Material.

Q16. How do you transfer data from SAP ERP system to SCM system?

Ans: To transfer master and transaction data from ERP system to SCM system, you need to define an integration model. When you create an integration model, system automatically generates a new version of this model.

Q17. Is it possible to keep multiple versions of integration model active at the same time?

Ans: No, you can create as many versions of an integration model as you want however only one version is active at a time.

Q18. What is Good issue process? What is movement type for Goods issue?

Ans: Goods issue is done when raw material is consumed to produce material as per Production order. When goods are issued, system decreases the inventory of components at the storage location in Production Planning system.

Movement type 261 is used for goods issue.

Q19. How do you manage cancelled goods issue for an order in SCM process?

Ans: Goods issue reversal is used when you cancel the goods issue for an order. Goods issue can be cancelled till order status is confirmed CNF in system.

Movement type is 262 in Goods issue reversal.

To perform goods issue reversal, use T-code: MB1A or go to Logistics → Production → Production Control → Goods Movement → Goods Issue

Q20. What is planned order creation? Can you convert a planned order to production order, how?

Ans: In SAP system, you can create a planned order request during planning run for a plant to trigger the procurement of material with the certain quantity for a specific time period.

Planned orders are created as result of shortage of materials that are set to internal procurement will create planned orders and you can convert planned orders to production orders using T-Code: CO40/CO41.

Q21. Is it possible to create a Planned Order manually, how?

Ans: You can create a planned order manually using T-Code: MD11.

How do you evaluate MRP run in SCM system?

This is used to see current stock and planned receipts. Use T-code: MD04

Q22. What is Material Requirement Planning MRP list?

Ans: MRP List is used to generate static report that contains planning run material wise and it displays time of MRP run at the top.

Q23. What is Production Order in Supply Chain?

Ans: A Production order is used to define the material to be produced, plant location where production has to be done, date and time of production, quantity of goods required. A Production Order also defines which components and sequence of operations are to be used and how the order costs are to be settled.

During creation of production order, where do you get the details of list of components and operational data in the order?

BOM and routing data of the materials are copied into the Production order which determines the list of components and operational data in the order.

Q24. What are the steps performed when you convert a planned order to Production Order?

Ans: First step is to convert a planned order to production order. When you create a Production Order, type is defined in SAP PP system.

To start the production process, it is necessary to issue Production order. Till a production order is not released, execution of production process is not started.

Issuing goods is required for providing the goods to execute the Production order. Once goods are issues, document number can be updated in the system.

All the sub processes are executed in accordance with required operations to confirm the production as per Production order.

Q25. While creating an integration model if you don’t select a restriction what happens?

Ans: When you don’t select a restriction, it prompts that a very long run time is expected if you select execute.

When an integration model is deactivated, it deletes all the objects that are transferred in SCM system?

No, when you deactivate an integration model, it doesn’t mean that all the objects that are transferred will be deleted in SCM system.

Q26. What is BOM usage type for Production?

Ans: 1

Q27. What are common Supply Chain master data types?

Ans:

BOM
Work Center
Material Master
Routing

Single-Mixed and Multi mixed Resources
Line Resource

Single-Activity and Multi activity Resource

In Single activity resource, one activity can be carried out at a time. In multi activity resource, several activities can be carried out at one time.

Single-Mixed and Multi mixed Resources

In SAP SCM, you use mixed resources to perform Production Planning SAP PP and Detailed Scheduling both the activities.

Now single mixed resources means that a single activity resources in Production planning PP and in Detailed Scheduling DS and multi-mixed resources allow multi activity resources.

Line Resource

It defines working time and rates of line. A line resource is created in APO for each line you create in DI system.

Provide some examples of manually created resource type in SCM system?

Vehicle Resource
Bucket Resource
Transportation Resource

Q31. What is Production Data Structure generated from R/3 system?

Q32. What are different types of Production Data Structure?

PDS for Production and Detailed Planning
PDS for Supply Network Planning
PDS for Demand Planning
PDS for CTM Planning
Template PDS for industry specific optimizer

Q33. What is the use of Core interface in generating Production Data Structure PDS?

Ans: SAP APO Core Interface (CIF) is known as interface that allows you to exchange data between SAP APO and ERP system.

You can perform the following functions using CIF −

Source and target system determination within complex system environments
Supply of SAP APO with the master and transaction data relevant to planning
Transfer of changes to transaction data.
Return of planning results from SAP APO

Q34. How do you change PDS data in Supply Chain process?

Q37. Explain Model and version management in SCM?

Ans: In SAP SCM, you use supply chain model for the planning. SAP system considers the master data that is assigned to a model for the planning purpose. You can assign the master data to a model either in the Supply Chain Engineer or in master data. Maintenance transaction.

It is also possible to assign one or more planning versions to a model. All the master data released for the planning must be assigned to the active model and the active planning version- model 000 and planning version 000 respectively. In production system all master data that you transfer from SAP R/3 is automatically assigned to the active model and the active planning version.

Q38. Is it possible to create multiple versions under a model in SCM?

Ans: Yes

Q39. When you delete a model, all the planning version remains available in system?
