Dear
Distribution Resource Planning
Distribution resource planning provides a framework for determining the need to replenish
inventory by:
Linking market requirements with manufacturing and demand management
Relating current inventory positions and demand forecasts to production scheduling
Matching material supply to manufacturing demand, and customer demand to product
supply
Process Flow
1. You define all nodes in the network including plants, distribution centers (DCs),
warehouses, and stock transfer points using the Distribution Network tool.
2. You set up the material master record for each node. In MRP 4 of the material master
record, you must define the deployment strategy for each material (the fair and push
distribution options) as well as deployment horizon (push horizon). For the push horizon,
enter the number of days for which the system considers the ATD quantity and any
additional quantity produced. Any quantity produced beyond the push horizon is not
considered in the deployment calculation.
3. To calculate an available to deploy (ATD) quantity, use the availability check rule, DE, in
Customizing, u2018Carry out control for availability check.u2019 The availability check and the
deployment checking rule, determine the MRP elements that are used to calculate the
ATD quantity.
4. You create a forecast for each DC; for example, a sales forecast.
5. You transfer the forecasted data to Demand Management. The system creates
independent requirements.
6. You perform a DRP run in each DC and in each supplying plant. The DRP run considers
the quota arrangements defined in the network, available stock, sales orders, and
independent requirements.
The DRP run in the DCs creates releases for stock transport requisitions in the
supplying plants.
The DRP run in the supplying plants creates planned orders for production.
7. You convert planned orders into production orders for manufacturing.
You run deployment to produce stock transport orders for distribution of stock from the supplying
plants to the DCs.
Distribution Requirement Planning :
Generates stock transport requisitions between locations.
Accounts for time-dependent safety stocks when the replenishment stock is calculated.
Initiates planning runs in a net change procedure or in a regenerative planning mode
Deployment
When demand is greater than supply, deployment calculates a fair share quantity based on the available-to-deploy (ATD) quantity and requirements in the distribution centers to be supplied.
When supply is greater than demand, deployment calculates distribution of stock using pull or push logic within the distribution network according to planned requirements.
Generates stock transport orders from suggested orders in the DRP plan.
Prioritizes quantities supplied based on requirements types (customer order, forecast, and safety stock).
Multi-Sourcing Using Quota Arrangements
Lets multiple plants supply a percentage of the material required by a single location, which makes it possible to prioritize the deliveries made by plants and to specify maximum delivery quantities for particular time periods.
Represents simple capacity constraints, and combines the percentage-based and maximum quantity approaches.
Lets you establish minimum, maximum, and rounding profiles for lot sizing within the network.
Lets you change the distribution network at future dates.
Lets you offset delivery times for specific items from the sourcing location to the replenishment location.
Single-Sourcing Using Special Procurement Keys
Hope this above details will be useful for your requirement .
