Master data is the set of data which
is commonly used across the entire organization and all business processes. Master
data is shared by different people for different purposes at the same time.
Information about material, customers, suppliers etc are not changing
frequently. Therefore if the users have to re-enter those information it will
be a huge waste of effort. Hence it’s efficient to keep this information in a
place which every user can access. SAP has defined master data for different
modules.
E.g.
Master data used in production
process
Bill of Material (BOM)
Work Center
Product Routings
Material Master
Production Resource Tools (PRT)
The importance of master data
definition of SAP is the introduction new management practices. For example some organizations have not
defined work centers in their manufacturing plants. Therefore SAP encourages
user to adopt best management practices across the industry. That’s why SAP is
not regarded as an ordinary software system.
SAP standard tables contain too
many fields. For example CRHD (Work Center Header) table contains 129 fields.
This is because SAP uses one work center header table across all modules of
SAP. Different people need different information about work center. LOART (Wage
Type) field is not important for production planners. It is important for the
FI or HR people who are responsible for salary making process. SAP provides
room for everyone to represent their data in a single work center header table.

Data redundancy and duplication
problems will not arise with the use of one database across the
enterprise. This will increase the system efficiency.
