Total Requirements (SAP Library - Material Requirements Planning (PP-MRP))

Total Requirements

Use

For industries such as the automotive industry, in which large numbers of sales orders for finished products with very many components are planned every day, the performance of the material requirements planning run can be improved greatly by generating total requirements for the components.

Prerequisites

Finished Product

You must be able to produce the finished product through repetitive manufacturing.

You have set the Repetitive manufacturing indicator in the material master (MRP 4 view) and entered a repetitive manufacturing profile.
You have selected the indicator for the generation of collective requirements in the repetitive manufacturing profile that you have entered.
If you want to assign costs to the material and not the sales order, you have created a production cost collector for the material.

Components

You have set the indicator 2 for Collective requirements in the Individual/collective field in the material master (view MRP 4).

Collective requirements are not the same as total requirements. In the case of collective requirements the individual requirements are still displayed with their pegged requirements. The system can display these collective requirements combined in a single line or completely expanded in the MRP list and the stock/requirements list. With regards to planning, collective requirements, like total requirements, allow all the requirements to be covered collectively using one procurement element.

Features

The system does not generate individual requirements for each pegged requirement. It does, however, generate a total requirement for each component, which contains the daily cumulated quantity of all dependent requirements for this component. For example, if 1000 sales orders are planned for one day, the system does not create 1000 individual requirements for the dependent requirement of a particular component, but creates a single total requirement (requirement quantity multiplied by 1000).

An individual requirement for components is generated in addition to the total requirement:

if the availability check is allowed for the material in the material master
if you have set the indicator 0 (zero) for the generation of total and individual requirements for the components in the Requirements grouping field in the material master (view MRP 4)
if the components in the planned order are firmed

You may not generate total requirements for components that are produced using make-to-order-production. You therefore enter the indicator 1 for Individual requirements in the Individual/collective field in the material master (view MRP 4) for the components.

Displaying the Total Requirements

The total requirements are displayed as an individual MRP element (TotReq) in MRP evaluations. You cannot access pegged requirements for these total requirements.

You can access the components, for which only total requirements have been generated, in a special list in the planned order. To do this, you select Total requirements in the header of the planned order. (This function is only provided if total requirements are available.) In the standard component list, the system only displays the components, for which individual requirements are presented.
