payment term end of month

[lists.j...@symetrie.com]

Hello,


Following https://bugs.tryton.org/issue2320
I should use value 31 in day field of PaymentTermLine
to obtain the end of the month.

I created a PaymentTerm thirty days + end of month
with the line
Remainder, days=30, day=31

Testing in 4.2 with the wizard TestPaymentTermView
I get March 2 for a date of January 2
where I expect to get February 28.

Is it a bug or did I misuse?

A misuse. The order of operations is important when using absolute and
relative in the same line.
See http://labix.org/python-dateutil#head-72c4689ec5608067d118b9143cef6bdffb6dad4e

So in your case what happens is:

January 2nd -> day=31 -> January 31 -> days=30 -> March 2nd

You must have 2 lines:

1) days=30
2) day=31

January 2nd -> days=30 -> February 1st -> day=31 -> February 28th
