When setting up a 2x a week serial, the frequency of 2x a week does not allow for correct Unit/Issues set up. Setting up a 2x a week frequency, 1. Unit = Week 2 Issues per Unit = 2 3. Units per Issue =.5 However, Koha does not accept a value of less than 1. Due to this, the frequency cannot be used as it is intended, Koha will predict the wrong frequency.
I think this is a misunderstanding, one of the columns issuerperunit, or unitsperissue must always be 1. The value of 1 here implies that the other value is the control i.e. if 'Issues per unit' = 1 then we determine frequency based on 'Units per issue' and vice versa. To set up 2/week you would enter: Unit: weeks Issues per unit: 2 Units per issues: 1 (meaning ignore) It seems to work correctly in my testing, can you add a screenshot of the issue if I am missing something?
The issue here is a serial published on Tuesdays and Thursdays. There is no way to indicate that issues are expected on specific days of the week. Would also be helpful for a serial published every other Thursday or similar
