Check Special
Procurement Types
In this step, you define the special
procurement keys which as well as the procurement type control the procurement
and storage of a material. The special procurement type always refers to a
procurement type.
You can now, also define how the system treats
the material as a component during the BOM explosion using control
indicators.
Example 1
(special procurement keys without other indicators)
The procurement type "external procurement" is
defined for raw materials. If a material is to be procured via a consignment
order, you assign the special procurement type "consignment" to the material
in the material master record.
Example 2
(special procurement keys with other indicators)
A material appears in several BOMs as a
component because it is assembled in finished products in in-house production.
It is procured from an alternative plant if no dependent requirements exist
for the material.
The same material, on the other hand, is also
sold from stock to customers, who need the material as a replacement part, for
example. In this case, the material can be procured by stock transfer because
with planned independent requirements (customer requirements, in this case),
procurement you cannot use withdrawal from an alternative plant.
You can do this by creating a special
procurement key using the stock transfer special procurement type and by
selecting the indicator for withdrawal from alternative plant. You assign this
special procurement key to the appropriate material in the material master
record.
Default
Settings
The following special procurement types are
defined in the SAP standard system:
For the procurement type, "in-house
production"
A phantom assembly
is a logical grouping of materials. These materials are grouped and managed
together for a certain reason (for example, from the engineering point of
view). However, a phantom assembly is not actually produced. Therefore,
phantom assemblies pass the dependent requirements directly to the lower BOM
level.
- Production in another
plant
In this type of
special procurement, material components are produced in a plant other than
the planning plant.
If you want to use
this special procurement type, you must maintain a special procurement key by
choosing 'planning plant -> production plant' for each
relationship.
- Withdrawal in alternative
plant
In this type of
special procurement, the material components are withdrawn in a different
plant to the planning plant.
If you want to use
this special procurement type, you must maintain a special procurement key per
'planning plant -> withdrawal plant' relationship.
This special
procurement key is used to displace the stocking level of a BOM. If you use
the planning strategy "planning without final assembly", the system only
assemblies the assemblies that lie one BOM level below the finished product
before any sales order has been received. If you want the stocking level to be
even further down the BOM structure, the components receive the special
procurement key "Phantom in planning". Assemblies with this special
procurement key are not assemblies until sales orders at finished product
level actually exist.
For the procurement type "External
procurement".
You use this special
procurement key to carry out consignment processing for a material.
Consignment is a business process in which the vendor provides material at the
customer. The costs are incurred by the vendor.
You use this special
procurement type to carry out subcontracting with a material.
In subcontracting,
components are staged at an external vendor and are used to produce the
required assemblies.
Here, materials are
ordered from the receiving plant and are delivered by the delivering plant.
The requirement is determined in the receiving plant.
If you want to use
this special procurement type, you must maintain a special procurement key per
'receiving plant -> delivering plant' relationship.
- Withdrawal in an alternative
plant
In this type of
special procurement, material components are withdrawn from a different plant
to the planning plant.
If you want to use
this special procurement type, you must maintain a special procurement key per
"planning plant -> withdrawal plant" relationship.
Actions
Checking the special procurement key
If you want to procure a material that is a BOM
component in a way other than those in the standard special procurement types,
you can define a special procurement type by selecting the following
fields:
- If you select Phantom item,
the system uses a phantom assembly in the BOM explosion for a material that is
used as a component in a BOM, regardless of which type of special procurement
has been set. The phantom assembly characteristics can be combined with any
other special procurement type.
- If you select Direct
production,the system uses direct productionin the planning run for a
material that is used as a component in a BOM. Direct production can be
combined with the special procurement type, production in an alternative
plant.
- If you select Withdrawal from an
alternative plant, the system procures a material that is used as a
component in a BOM by withdrawing it from an alternative plant. This only
occurs if dependent requirements exist and is not dependent on the special
procurement type defined.
If you use storage location MRP and production
or procurement is carried out directly for the storage location, you must
create the following special procurement key:
- in-house production (procurement type 'E',
special procurement 'E')
- external procurement (procurement type 'F',
special procurement blank)
Further
notes
The special procurement type is assigned in the
material master record per material.
The
procurement type is defined in Customizing for the material
master record, in the type. This means that every material is assigned the
appropriate procurement type when creating its material master
record.
If you have selected the Phantom item field or
direct production field for a special procurement key but you want to switch
off this procurement type for a certain BOM item, select the appropriate key
in the BOM item in the explosion type field. To maintain the explosion type in
Customizing for the Bill of Material, choose Item Data -> Define explosion
types.
Activities for
Costing
If you want to cost a material as an
externally procured material by ignoring its quantity structure,
you have the following options:
- In the material master record, go to the
MRP view and enter the procurement type
F and enter no special procurement type
(neither in the MRP view nor in the
Costing view).
- In Customizing for special procurement types,
create a new special procurement type (procurement type:
F and special procurement type: empty) and enter that special
procurement type in the Costing view of the
material.
If you want to cost a material by ignoring its
BOM but including its routing, you must create a new special procurement type
in Customizing for special procurement types (procurement type:
E and special procurement type: E) and
enter that special procurement type in the Costing
view of the material's master record.
