CAN ANY ONE TELL ME What is the use of fallowing structures
1)BDCDATA
2)BDCMSGCOLL

Answer

BDCDATA standard structure contains following parameters.

program :name of the module pool programm.
dynpro :screen number
dynbegin:it indicates for the new screen
fnam :name of the fields in database
fval :fields values are assinged with the fields

by defineing that structure bdcdata as it_bdcdata and work
area wa_bdcdata and we can pass above values.

ex: wa_bdcdata-program = name of the module pool program.

and

BDCMSGCOLL this is the structure to keep the errors while we
are using call transaction method in bdc.

ex syntax:

call transaction 'va01' using it_bdcdata mode a/n/e update
s/a messages into it_bdcmsgcoll.
