BDCmeans batch communication data. transferring the data
from Legacy system to sap system,means from non sap system
to sap system. it is unidirectional,means uploading the data
from non sap to sap system.Let u know one difference to bdc
and lsmw. lsmw is bi directional, means transferring the
data from non-sap system(legacy) to sap system and sap
system to non sapsystem.but where as in bdc uni directional
only.
In BDC there is 3 types.
Call Transaction-Transferring data to sap system directly.
Session Method-Transferring data to sap system through sessions
Direct Input- directly entering the data.
Mainly Call Transaction and Session Method are important
