Hello everybody,  
I tried to modify my invoice numbers in my LibreOffice template to

> RE {yy}-{0000}

but always get just the figure eg. “4” (instead of “RE 20-0004”). Variants like

> RE\_{yy}-{0000}  
> {0000}

etc. didnt work either.  
I tried all of these variables:

> {object\_id}  
> {object\_ref}  
> {object\_ref\_ext}  
> {object\_ref\_customer}  
> {object\_ref\_supplier}  
> {object\_note\_private}  
> {object\_note\_public}  
> {object\_note}

but none works, all are only showing the plain number. Is it a bug? Help would be highly appreciated.

Cheers,  
Wolf

Hello,

You should define invoice number at invoice module customization and enable it.  
After that you should use {object\_ref} on your odt template.
