Answer 1

Hi,
   call transaction method returns sy-subrc value
   but session will not return subrc value.
   error records can
   be again reprocessed in session method using
   session name.
   Using call transaction If any error occurs you
   can store the recorss in internal table and
   send this records to BDC session by
   calling BDC_open_group,BDC_insert,BDC_close_group
Error Analysis and Restart Capability
Unlike batch input methods using sessions, CALL TRANSACTION USING processing does not provide any special handling for incorrect transactions. There is no restart capability for transactions that contain errors or produce update failures.
You can handle incorrect transactions by using update mode S (synchronous updating) and checking the return code from CALL TRANSACTION USING. If the return code is anything other than 0, then you should do the following:
write out or save the message table
use the BDCDATA table that you generated for the CALL TRANSACTION USING to generate a batch input session for the faulty transaction. You can then analyze the faulty transaction and correct the error using the tools provided in the batch input management facility.
