What is serial number in material master
Serial numbers are used to uniquely identify material and
technical objects. The serial number profile defines how and when serial
numbers are assigned to material and technical objects.
A serial number can be assigned to a material
only after a serial number profile is created.
It is important to solidify the business
processes pertaining to serialization prior to creating the serial number
profile. The following issues should be
discussed:
·
What materials will be
tracked?
·
When will serialization
occur? (Which business transaction?)
·
Who will be responsible for
serialization? (Which end user?)
·
Will serial numbers be
internally or externally assigned?
The serial number profile documents these
decisions and is then assigned to a material's master record. Later, this material serial number is
assigned to an equipment master allowing access to the complete order processing
and maintenance history functionality.
Create Serial Number Profile
A serial number profile
defines the conditions and transactions governing the assignment of serial
numbers to technical objects. This group
of configuration data is represented by a four digit code
which must be entered in the material master
record before a technical object can be assigned a serial number. The serial number profile is defined in
Customizing for Plant Maintenance.
The serial number profile contains important
serial number creation and assignment rules.
Serialization can occur in different components such as SD - Sales and
Distribution, MM - Materials Management and QM - Quality Management. The serial number profile establishes the
business transactions for which serialization:
·
Will not be carried out
·
Can be carried out
·
Must be carried out
·
Automatically is carried
out
In addition, the serial number profile specifies
whether or not an equipment record is automatically created when a serial
number is created or specified during a business transaction.
The serial number profile also defines the
prerequisites for serialization during certain business transactions. For example:
·
Material serial numbers do
not need to originate from material masters
·
Material serial numbers
must originate from material masters
It determines the type of material number being
created by the equipment category specified in the serial number profile. Equipment categories group like technical
objects according to their use and are used here to classify the technical
object being serialized. If no equipment
category is specified then the technical object is classified under a default
category.
Since serialization functionality crosses into
several different SAP modules it is important to coordinate the design of the
various integration points before configuring.
Assign Serial Number Profile to Material Master
A material master record contains all the data
required to describe and manage a material.
However, it does not allow differentiation between the individual items
of the technical object. If a company
services and maintains large numbers of similar objects, for example personal
computers, identifying individual pieces of the material are important for
tracking quality issues, maintenance history, etc.
To establish a material's uniqueness it is
assigned a serial number. In order to
create a material serial number combination in the system a serial number
profile is assigned to the particular material's master record. The material serial number combination, when
assigned to an equipment master, allows end users access to the complete order
processing and maintenance history functionality.
