is there any way out for copying a number of items at a time, in a BOM, while keeping the earlier items intact

say A BOM has

1,2,3 items

I want to copy 1,2, &3 at a time so that the BOM looks like

1,2,3,1,2,3

I am using ERP ln 6.1

Of course , you can do it by using programming logic or DBA Tools.
But you should be carefull by doing it .If you ask me HOW ?
search board and examine your structure.

Good luck !
