Hi,
as in the title if you active experimental HRM module, on Establishment tab you will get a ‘label’ column is missing error on Postgresql database, i did not tried on mysql or mariadb. here is the script you should run on you db if you want to test or use the module;
ALTER TABLE IF EXISTS public.llx_establishment
ADD COLUMN label character varying(50);
ALTER TABLE IF EXISTS public.llx_establishment
ADD CONSTRAINT llx_establishment_label UNIQUE (label);
Ps: this is not an official approach this is just me trying to figure it out to test the Module.
good luck.
