Bahmni drug dosage form vs openerp drug UOM

I imported all kind of drugs to openmrs and they get synced fine with OpenERP. However I notice that the drug form in OpenMRS is different than the one in OpenERP.

Do I need to update drug UOM manually one by one in OpenERP (for instance "Puff, ml,g) ? Currently the UoM of all drugs is “Unit” in OpenERP.

Am I missing some steps here ? Any feedback on this is very much appreciated.
