6.0.1 account_voucher - supplier vouchers - tax issue

[Vadim - Enapps LTD]

account_voucher > supplier vouchers - changing the calculated tax and total will not work properly and will give an error upon validation.

To replicate:

1 - create a new voucher.
2 - add a new expense line - lets say for EUR 100
3 - choose a tax code
4 - click on compute tax
5 - change the calculated tax amount (deduct 0.01)
6 - change the total (deduct 0.01)

Try to validate and it wont work.

The normal invoices work properly - you can change the calculated tax as you wish and you can validate, so I believe this should be updated to follow the same logic.

Hello,

Thanks for your suggestion!

Here you are changing the base amount directly from the voucher instead of tax object. So it did not allow you to validate the voucher as the value is computed from original tax object.

But this trouble can be prevented by putting constraint on modification of such amount, So I am confirming this bug.

Thanks.

Hello Vadim,

You are chaining the calculated amount of tax and total on voucher. So we can not change it manually. We can put it readonly on these two fields.
So when you try to validate voucher it raise error for non-balanced entry.

And for invoices we can not change the tax amount on it because its readonly for user.

So i agree with you and we will try to fix it in next version.

Thanks,
mra

Hi Mustufa,
> And for invoices we can not change the tax amount on it because its readonly for user.

you CAN change the tax on invoices, and it will be ideal if you can apply the exatly same logic on purchase/sales vouchers.
