I have sales invoice No i need to modify in sales invoice header and line
Ex
Sales Inoice No in sales invoice header table(No field)
inv-002
inv-003
inv-004
inv-005
I want to modify this values as following :

Sales Inoice No in sales invoice header table(No field)

inv-0012
inv-0013
inv-0014
inv-0015
but when it modify it will not effect in any values in database (meaning from inv-0012 to
inv-0015) not found in any place in database
How i do that by writing code if possible

Because i make integration between two databases and I replaced this or i need to modify this no to not make duplicate or conflict in primary key when transferred.
database A
No customer
inv-002 ahmed
Database B
No customer
inv-002 ali
when transferred done
inv-002 ali will found in sales invoice header and
inv-002 ahmed will be removed
so that i change no by writing code are this possible by setrange
thanks
