Unit of measures
This module is probably the most frequently installed, but the least frequently required. It is uploaded via the warehouse, using the “Units of Measure” setting. The description clearly and unambiguously states, „sale and purchase of products in different units of measure“. And therein, exactly, lies the rub: this module is required only if the unit of measure in purchase is different from the unit of measure in sales (e.g. gallons vs. liters, roll vs. square meter).
Even if we see this time and again, the module is definitely not intended for displaying the unit of measure of a product in quotations, order confirmations or delivery notes.
This, of course, leads to the question, how else do you identify a difference in units of measure, if not via this module? The answer is simple: you file this information directly in the product description or create a dedicated field for information on the product, which then gets inserted and displayed in the respective customized document templates (this procedure, however, would run under the heading „adjustment“).
Account_cancel: „Cancel Journal Entries“
This module is probably an even worse candidate, since it allows any operator to cancel records that have already been booked! Any accountant worth his salt would throw up his hands in disgust, since such a procedure would completely undermine revision safety of bookings. After all, a posting record, once booked, may only be cancelled by an off-setting entry.
This, of course, occurs most frequently during invoicing, due to incorrect invoicing addresses or changes made in incorrect invoicing addresses, incorrect discounts, incorrect product text, incorrect quantity or incorrect accounts. A number of reasons are conceivable here.
This is why some admins will certainly consult the Odoo App Store and find this questionable module. After all, its description seems to fit the issue exactly.
However, the correct procedure should be:
