Hi
BDC (Batch Data Communication) works based on the data in the Internal table of structure "BDCDATA", and some of the very important lines with information (in sequence) Dynpro, Cursor-field and Data Fields, then call Transaction / Session Creation Logic.
In Call Transaction method of BDC, the Message is handled manually using the structure "BDCMSGCOLL" and by refering to messages in "T100" Table. [Refer the standard Include BECRECX1 for more information.
BDC can be created by Recording tool or my scracth creating a new program. Use transaction code 'SHDB'.
A sample code by using the Recording method (Here both Call transaction and Session Method of BDC will be created by standard Recording tool [this you can find in include BDCRECX1])
Code Only the Program, withoug Include BDCRECX1 (This std, inclu you can find)

Refer this link as an example:
<b>http://www.sap-img.com/abap/bdc-example-using-table-control-in-bdc.htm</b>
Alternatively, Press the Item To Top Button(The 4th from left)Under the Item Table control, every time you want to enter item details,
This would bring the item to the top of the table control every time.
Record the transaction this way, and code for your BDC.
Another alternative is to use a bapi:
<b>BAPI_SALESORDER_CREATEFROMDAT2</b>
