Hello, I use delibarr since 2-3 years. I update my version will stable versions. I have an issue with the mercure numbering module after upgrade to 2.7 from 2.6.x In the configuration screens, I selected the Mercure numbering with : FA{yyyy}-{0000@1} NC{yyyy}-{0000@1} This display as example FA2010-0001 for the next number… but when I create an invoice I have the terre version applied FA0501-0001… which is note the default one. Can you tell how I can solve this? I cant do invoice at the moment :unhappy: Baris ---

Go into table llx\_const and run the sql command delete from llx\_const where name = ‘FACTURE\_ADDON’ the go on dolibarr and rechoose mercure as numbering module. It should works after that. Other solution, try with 2.7.1 (bugs seems fixed with 2.7.1). ---
