Hi Ekow,
This is a bit intentional.
Many units like “ml”, “teaspoon” etc, which a medical practitioner uses while ordering a medicine, cannot be directly converted to units in which pharmacy sells the medicine . e.g Let say doctor orders 5 ml of Syrup, twice daily for 7 days i.e. 70ml of syrup, but pharmacy sells the syrup in “Bottle of 100ml” unit only. So while syncing drug order from OpenMRS to ERP, we add “70ml” in comments section with quantity as “1” and unit as “Bottle of 100ml”. Billing Clerk/Pharmacist will manually check before confirming the sales quotation.
Now for units like “Tablets, Capsules etc”, its easy to sync the quantity directly. So there is a setting in ERP to enable the quantity sync for such units. Goto “Sales > Units to be Synced” > Create > (Enter unit name) > Save" . This should sync correct quantity for configured units.
