Regarding Bill series

You can Raised Bill in two different no 

For First Premises Bill No Start PR1/01

For Second Premises Bill No Start PR2/01 

so now onwards i will start generating bills as below mentioned


A/001 TO WHEREVER IT GOES UPTO MAX IT WILL REACH 300


and for second branch

B/501 TO WHEREVER IT REACHES UPTO..


the method you provided is correct but i want the invoice number series also different so that no confusion whenever a client give a refernce of particular invoice number then we just have to search that invoice in respective premises..
so if i am anywhere wrong then do correct me
