1. Introduction:In this document we will learn more about Production Planning and MRP. So stay tuned. 1. Planning Related configuration The following three are the important planning methods in SAP: MRP Consumption based planning SOP & Flexible planning Let us now try to understand MRP and Consumption Based Planning thoroughly. In this step of MRP & Consumption Based Planning we will have to configure the following related steps: ü Configuration of Plant parameter ü Configuration of MRP type ü Configuration of Planning Strategy ü Configuration of Requirement type ü Configuration of Requirement Class ü Configuration of Lot size procedure
2. MRP Related configuration settings 2.1 Define Number Ranges for Planning run BACKGROUND This configuration setting enables to define the number Range interval for planned order, purchase requisition. Number range interval has to be defined for both planning run and for Manual process. MRP run will consider the number range interval for planning run and in turn it is assigned in the plant parameter. Manual number range interval will be used when creating the planned order or purchase requisition manually. This will help to assign the different number range series for different document type.

This is then used for dispatching the planned orders in the graphic planning table. ..more explanation given below (***) Type of scheduling. Whether Backward, forward or only capacity requirements. Select backward to automatically determine the start date. Leave the entries as it is.
** Adjust Dates:In backward scheduling the system adjusts the basic start date if necessary, in the case of forward scheduling the basic finish date. The basic finish date is not adjusted in planned orders. There are the following possibilities:
• The basic dates are adjusted and the dependent requirements are scheduled for the start dates of the relevant operations. • The basic dates are not adjusted and the dependent requirements are scheduled for the start dates of the relevant operations. • The basic dates are adjusted and the dependent requirements are scheduled for the order basic start date. • The basic dates are not adjusted and the dependent requirements are scheduled for the order basic start date. How the system adjusts the basic start date in backward scheduling is described below. During scheduling, it starts at the basic finish date and redetermines the production dates and the basic start date. If the new basic start date differs from the old date in the order, the system copies the new basic start date to the order. If the new production start date is before the old basic start date in the order, the system reduces the lead time - if you have set reduction up- before it adjusts the basic start date. It tries to reduce the lead time sufficiently so that the production dates are within the old order basic dates. In the case of forward planning, the system correspondingly - apart from planned orders. *** Capacity Scheduling
procees
• The basic dates are always adjusted and the dependent requirements dates of the components are always set to the start dates of the operations. • The basic dates are always adjusted and the dependent requirements dates of the components are set to the order start date of the planned order. • The basic dates are only adjusted if a delay occurs (for example, if the dates gave to be postponed meaning that the delivery date be adhered to), and the dependent requirements dates of the components are set to the start dates of the operations. • The basic dates are only adjusted if a delay occurs and the dependent requirements dates of the components are set to the order start dates of the planned order. When dispatching the planned order in the planning table, the order finish date is also adjusted. Click Save

INSTRUCTION Follow the Menu Path: IMGàProductionàMaterial Requirement Planning àPlant parameters à carryout over all maintenance of plant parameters Click Click Enter Plant IND6 Click Click
Update the Following fields Field Rescheduling Horizon
Description It is the total number of working days during which the procurement proposals are rescheduled. Starting from the end of the replenishment lead time (the system calculates the end of the replenishment lead time by the planning date + number of days for the replenishment lead time), in which the system checks in the net requirements calculation whether firmed or fixed receipt elements (purchase orders, production orders, firmed planned orders, and so on) should be rescheduled in. The rescheduling horizon is calculated in workdays. ..more explanation given
Tolerance value forward
Tolerance value backward
below The system compares this value with the number of days which results from calculating the difference between the requirements date and the delivery/order finish date. If the difference is greater than the comparison value, the system provides the receipt elements in question with an exception message and a rescheduling proposal that is based on the requirements date. The system compares this value with the number of days which results from calculating the difference between the delivery/order finish date and the requirements date. If the difference is greater than the comparison value, the system provides the receipt elements in question with an exception message and a rescheduling proposal that is based on the requirements date.
Use of rescheduling Horizon:-
In this period, rescheduling proposals are created by the system for firmed or fixed receipt elements if this receipt element can cover the requirement and if the tolerance values for rescheduling in have been exceeded. In this case, no new order proposal is created - instead the system includes this fixed receipt in the net requirements calculation with the rescheduled date. Firmed elements
