PTI : Plan to Inventory


Plan to Inventory (PTI), is another term used for inventory planning. In any organization or business, PTI in SAP refers to the entire supply chain-related inventory management process. This includes forecasting and estimating the optimal quantity and timing of inventory to align it with sales, fulfillment, and production capacity, to ensure higher customer satisfaction levels. Inventory planning focuses on optimizing a company’s cash flow and profits while contributing to an efficient supply chain. Thus, the PTI cycle in SAP helps to determine requisite product quantities to carry out future sales. 

An efficiently functioning plan to inventory process in SAP, needs an understanding of what products should be purchased and in what quantity, to maintain optimal stock levels. In the plan to inventory cycle in SAP, sales or demand forecasts for products are based on historical trends, therefore helping to eliminate inventory overstocking, stockouts, lost sales, and dissatisfied customers.

How does the Plan to Inventory cycle in SAP work?

To explain how a PTI process in SAP operates, here are the main components of an inventory management plan:

1. Demand planning: The first step in the plan to inventory cycle in SAP is to forecast and plan for future demand for products. This is typically implemented using SAP’s Demand Planning (DP) module, where historical sales data, market trends, and other relevant factors are analysed and used to create demand forecasts. These forecasts help determine the expected quantities of products that need to be produced or procured, thereby eliminating understocking, or overstocking of inventory.

That said, two key factors to consider when estimating demand are product scarcity and competition. For commodities that are hardly available, keeping backup supplies or stocks of the same would help meet demand spikes. Additionally, if product scarcity results in customers switching to competitors, the extra storage cost in retaining stocks is preferable to losing customers.

2. Materials requirements planning (MRP): Once the current & future demand is determined, the Materials Requirements Planning (MRP) process kicks in. MRP is used to calculate the materials required for the production or replenishment of inventory. It considers key elements like lead times, existing inventory levels, safety stock, and planned production quantity to generate procurement proposals and production orders.

3. Replenishment planning: A sound replenishment strategy goes hand in hand with materials requirements planning, helping to maintain smooth and steady production supplies. The reorder point (ROP) is a threshold that determines the opportune time to place orders with vendors. ROP is determined by the time needed for vendors to package and deliver products and prevent any potential supply issues. A replenishment strategy should consider regularly and scarcely demanded products. A just-in-time (JIT) inventory system works when the supply chain is consistent and steady.

4. Purchasing and procurement: In the case of externally procured items, purchase requisitions (PRs) or purchase orders (POs) are created based on the MRP proposals. These documents trigger the procurement mechanism and eventually lead to the receipt of goods in the warehouse.

5. Production planning: For internally manufactured items, the MRP proposals trigger production orders or planned orders. These orders are used to plan and implement the production of goods based on demand patterns and inventory requirements. SAP Production Planning (PP) modules support the planning and scheduling of production activities, ensuring efficient use of resources and meeting existing demand requirements.

6. Inventory planning: The warehouse should be able to store extra inventory during critical periods. Inventory planning software is used in conjunction with chosen inventory planning techniques to forecast inventory needs, and avoid stockouts, overstock, and deadstock.  Inventory planning software helps to automate and optimize complex and critical inventory processes, letting businesses know when they need to purchase or transfer inventory to support sales or demand across multiple channels.

7. Goods receipt (GR) and inventory management: When goods are received from vendors or after production is completed, the inventory is updated in SAP PTI through goods receipt transactions. The inventory levels are then adjusted accordingly, and the system reflects the changes in stock availability. SAP Inventory Management modules efficiently manage the tracking, valuation, and control of inventory levels at all times, ensuring accurate stock quantities and timely replenishment.

8. Inventory tracking, monitoring, and reporting: PTI in SAP provides various reports and tools to monitor and track inventory levels, stock movements, and other relevant parameters. This information helps organizations make informed decisions on inventory management and its various elements, like reordering, replenishment, or variability in production schedules.

The efficiency of any inventory management system depends on its robust tracking mechanisms. A point of sale (POS) system categorizes inventory and records changes in real time. The usage of barcode scanners also reduces errors in tracking and increases efficiency.

8. Adaptable and adjusting stock levels: Any inventory system needs to be monitored and adapted to meet present and future product demand. Agile monitoring systems help to forecast situations when sales are needed to dispose of stagnant inventory, or when it is time to stock up on certain items to meet growing demand.

9. Warehouse Management: SAP Warehouse Management (WM) modules support efficient warehouse operations and management, optimizing the storage, picking, and shipping of goods.

10. Logistics Execution & Goods tracking: SAP Logistics Execution (LE) modules integrate various logistics processes like shipping, transportation, and tracking of goods.
