Regarding Table comtrols in BDC...

Normally all the screns with table controls will have buttons to add(Insert) a Row, Delete a Row etc..
After adding data to 1st Row (it will have index 1)... press that insert button so a new Row is inserted again at 1st row..so this will have index 1.
So in this way you can hard code the index to one.
The advantage is that if there are many rows then you will not have to keep a track of how many rows are inserted and when to press the page down button.
I am giving a small example.... Just copy paste this example and run it in all mode...
Run it in all mode so that you can see what I am trying to do...

Note : this is an relatively easy method.. not the only method to do...

Bdc Approach is Screen and function code interface.
When enter the screen we required enter multiple Data
same screen.
example va01. at enter qty and material fields. if system allowed only Limited entries. after press enter system allocated some entries. finally save button.
This logic recorded in SHDB Transaction.
loop at it_vbap into wa_vbap.
concatenate 'VBAP-AMTNR(' V1 ')' Into field.
perform sub_fld v1 wa_vbap-matnr.
" we assum system allowed 5 entries after enter data again 5 fields allowed.
v1 = v1 + 1.
if v1 = 6.
v1 = 1.
perform sub USING 'BDC_OKCODE. '00/'.
PERFORM SUB1 USING 'SAPMV45A' '4100' 'X'.
perform sub USING 'BDC_OKCODE. '00/'.
endloop.

ABOVE CODE FOR SAMPLE .
