Dear Poncho
I really appreciate your time for help ...
I create new inventory location ...and also tried with point of sale and even i create new sales areas ...
the problem is how can i link this with the reference number ?

Dear Poncho
So thanks
But my question is: Is it possible to use the Prefix automatically without user selection ...I specify many prefix for the same sales invoice as example ...i e RYD and JED ...but the problem is the user has to select between these prefix ...
Is it possible to make this prefix automatic comes with each user without his selection ?
Or is there any way that i can link the user with specific Prefix ?

i am trying to use the Prefix with each specific area for our branches ...i.e JED , RYD
Is it possible to make the Prefix comes automatically without user selection when they issues the transaction ..?

Dear Apmuthu

Dear Apmuthu
So thanks for help
I tried to include that in transaction reference but i get this error
Missing numeric placeholder. If you want to use template based references, you have to define numeric placeholder too.

Dear Ponocho
I appreciate your feedback ...but my question is how can i use {UU} ...is it some thing that i have to change in the
