What is Planned Independent Requirement(PIR)?

Planned Independent Requirements (PIR) are used to perform Demand Management functions.

A Planned Independent Requirement contains one planned quantity and one date for a material, or one planned quantity split over time according to dates.

  • PIR version "00" has an active indicator, which specifies that requirements would be considered in Material Requirement Planning (MRP).
  • If you want to maintain a number of versions of planned independent requirements, but do not want to include all versions in the material requirement planning run, you can set some versions to active and others to inactive, which could be used for simulations in Long term Planning.
  • PIR's are associated with requirement type which is driven from planning strategies in the material master, which determines methods of planning – Make to Stock or Make to Order.
  • PIR's are displayed in stock requirement list so that Planner can see and plan the production based on it.
  • PIR's are generally used in Make to stock environment where business wants to build the stock based on the forecast and not on sales orders.

Impact of Planning Strategies

  • Planning strategies are broadly categorized into Make to Stock (MTS) and Make to Order (MTO).

Make to Stock

  • Make-to-stock production is implemented if you produce stock without waiting for sales orders to arrive because you want to deliver your customers immediately with materials from that stock later on. You might even want to build stock without having sales orders, if you predict that there might be customer demand in the near future.
  • Make-to-stock strategies are usually associated with a lot-size key or a rounding value. For example, you may want to produce the entire amount for the whole month once in a month only, or you may want to produce for the exact PIR quantity.
  • In Planning Strategy 10, only PIR quantity is considered for MRP run and sales orders are completely ignored. PIR is reduced when you deliver the stock to the customer. PIR has requirement type LSF.
  • In Planning Strategy 40, Max of 2 (PIR and sales orders) are considered for MRP and PIR is reduced as soon as sales orders are entered. PIR has requirement type VSF.

Make to Order

  • You do not want to produce finished products until you receive a sales order from the customer.
  • PIR are not considered in MTO, and only sales orders are considered in MRP.
  • You produce sales order stock and can deliver to the specific customer only unlike in MTS scenario.
  • Planning strategy (20) is widely used for make to order process and strategy 25 is used for MTO with variant where customer asks for variants in products.

Troubleshooting

  • There might be the case wherein material master record does not exist. For this, you need to create the material master for the material before creating PIR.
  • Ensure right planning strategy is in place in material master which drives the requirement type of PIR and based on that PIR is considered in MRP run.
