Call transaction process is synchronous that is why it
returns SY-SUBRC, where as Sessions methods process is
asynchronous, so it will not return SY-SUBRC.

Answer / hitesh g

Session method doesnt return sy-subrc means, the records
that are uploaded are not saved in database, but are
temporarily residing in Session. Once u process the
session, then only, the data will be stored in database.
Where as in Call Transaction, after the execution of Call
Transactin method, the records will be update into database
according to Synchronous/Asynchronous method.

in session method it should not a return value . because of
the while u transfer the data from the legacy system to sap
system it sholud not check the values.but in the call
transaction method compalsory check the values
mandatory.and also the in the call trasaction method its a
function so compalsory sholud return the value.

Answer / mahender achhe

In both the case we can use "SY_SUBRC". It is system
defined object. "SY_SUBRC" is mainly used in BDC Call
Transaction and BDC Session. The "SY_SUBRC" object is used
whether the records are Successfully Inserted or not, for
that we can use "SY_SUBRC".

IF SY_SUBRC=0 -->Successfully Insert/Updated the records in
table.
IF SY_SUBRC=4 --->Not Inseterd.Updated the records in table.

In call transaction return the "SY_SUBRC",because records
are dump at a time. but where as Session not return.why,
because if any error occurs in the program it will not open
the first. i.e (BDC_OPEN_GROUP) so that it can't be read
the data from the table.

The main thing is initially it can't be open the table.
