You can change the way the Referencing works by going to Settings 


Within Settings - select Reference generator



You can edit or change the reference to suit. 


I.e Property prefix is currently 


P%04d


P = prefix

04d = number of places 

 

This will result in 

 

P0001

 

You can change the Prefix by selecting edit next the reference you would like to change and simply replace the letter "P" with something more suitable to your requirements.

 

 


 

This will now generate the property reference to display as:

 

MP0001
