Hi Guru,
The basis for deciding which method to upload the master data can be considered on the following:
1. Customer Requirement.
2. Volume of the data.
3. How much effort is required.
4. Whether error handling is to be done explicitly or automatically.
The most preference order as follows:
1. LSMW
Latest tool and less effort/coding is required. It covers all the methods.
by standard Batch/ Direct input,
by Batch Input Recording,
by Buisness Object Method , and
IDoc ( Intermidiate Document) .
2. BAPI
BAPI is an abbreviation used for Business Application Programming Interface. These are interfaces within the business framework to link SAP components to one another and SAP components with third-party components.
The SAP Business Objects are an essential part of the Business Framework and the prerequisites for interoperability. SAP Business Objects cover a broad range of R/3 business data and processes and can be accessed using BAPIs. The SAP Business Objects and their BAPIs thus provide an object-oriented view of R/3 business functionality.
3. BDC
It can be done in two ways:
a) Session - it handles error implicitly .
Transaction: error handling is explicit.
b) Call transaction is 6 times faster than session .
c) Session can handle multiple transactions while, call transaction can handle one transaction at a time.
d) Session method is used to handle basically very lage amount of data .
