a reason to do it by category would be: stock unit = kg, purchase unit = pce. Therefor you would define 'pce' in category 'weight' as well....

To avoid confusion and inconsistent data, the name of the unit should be unique (per category). This is, among other usages, quite neccessary for external unit conversion e.g. programs contacting OpenERP via xmlrpc. _______________________________________________ Mailing list: https://launchpad.net/~c2c-oerpscenario Post to : [email protected] Unsubscribe : https://launchpad.net/~c2c-oerpscenario More help : https://help.launchpad.net/ListHelp
