================================================= Variable quantity in contract recurrent invoicing ================================================= With this module, you will be able to define in recurring contracts some lines with variable quantity according a provided formula. Configuration ============= * Go to Sales > Configuration > Contracts > Formulas (quantity). * Define any formula based on Python code that stores at some moment a float/integer value of the quantity to invoice in the variable 'result'. You can use these variables to compute your formula: * *env*: Environment variable for getting other models. * *context*: Current context dictionary. * *user*: Current user. * *line*: Contract recurring invoice line that triggers this formula. * *contract*: Contract whose line belongs to. * *invoice*: Invoice (header) being created. Usage ===== To use this module, you need to: * Go to Sales -> Contracts and select or create a new contract. * Check *Generate recurring invoices automatically*. * Add a new recurring invoicing line. * Select "Variable quantity" in column "Qty. type". * Select one of the possible formulas to use (previously created).
