SAP ERP Manufacturing - ProductionPlanning (SAP PP): Different types of Scrapsin SAP

Document on Scrap

The following are the various scraps that are maintained

1. Assembly Scrap2. Component Scrap3. Operation Scrap

2.0 Assembly ScrapScrap that results from the production of an assembly.

-You have to maintain the assembly scrap in the material master (MRP 1 view) as a

percentage in the Assembly scrap field for the assembly header material.-The system

automatically increases the quantity to be produced by the percentage of scrap.Note:

Assembly scrap increases the order quantity of the assembly and subsequently increases

the order quantity for corresponding components. The dependent requirements of the

material components are therefore increased correspondingly.Dependency:

The system increases the quantity to be produced for all of the assembly's components accordingly.

Component Scrap: scrap of a component that may break during production of an assembly.

-You can enter values for calculating component scrap in the material master or the BOM

in the BOM on the Item Detail Screen General Data (data block for quantity data). This

component scrap is only relevant for the individual BOM.-In the material master (view

MRP 4) in the Component scrap field. This component scrap is relevant for all BOMs.-The component scrap quantity maintained for a material component in the BOM has the

higher priority.Note: Component scrap increases the dependent requirements quantity of

the component.In the BOM on the Item detail screen: basic data under Quantity data. This

component scrap is only relevant to the individual BOM.

In the material master record on the MRP 4 screen under Requirements explosion. If

the same component scrap applies to a material in a number of BOMs, then it can be

maintained in the material master record.

Component scrap is used in material requirements planning (MRP) to determine thequantities of components required. When exploding the bill of material (BOM), the system

increases the required quantities of the components by the calculated scrap quantity

Component Scrap - Dependencies

Component scrap maintained for a material component in a BOM overrides the

component scrap maintained in the material master record.

If there is also assembly scrap for a higher-level assembly, the system adds together

the two types of scrap

BOM Item detail screen: Basic data

If the component scrap is only relevant to the individual BOM, then it can be maintained in the BOM

Item detail screen

Operation Scrap: Before high-value components are built into an assembly, the system

carries out a quality control check of the assembly, if necessary. Faulty materials that were

taken into account in assembly scrap are not passed on to the next operation. They are

removed. Therefore, for a high-value component, you plan using operation scrap instead

of generalassembly scrap.-You can maintain the operation scrap in the BOM, on the Items

Detail Screen: General Data, under quantity data. You must also set the operations scrap

net indicator at the same time.-This scrap quantity refers to the quantity of one component

that is to be processed in an operation meaning that the planning run is more exact and

you can determine service and quantity consumption more precisely.-If the component is

contained in an assembly, for which an assembly scrap quantity has been maintained, the

system only takes the operation scrap into account.-The net indicator instructs the system

to calculate the component operation scrap without taking assembly scrap into account

(net usage scrap).Note : You should also set the net indicator, if operation scrap has not

been maintained and assembly scrap has been entered. The assembly scrap should not,

however, be taken into account.

Assembly scrap - maintained in MRP-1 view2. Component scrap - Maintained in MRP-4 &BOM, BOM will be the first priority3. Operation scrap - maintained in BOM level.

Thanks Srini for sharing ur knowledge on types of Scrap. This is a ready reference to know

on Scrap. Thanks again.
