Hi all, This is a paste from bug 17656: == The current irregularity feature works with saving internal fictive issue numbers in a text field irregularity. If you edited/shifted some dates in serial collection, you might be surprised what happens. You cannot view the saved irregularities in serial collection (I only see e.g. 2 issues on the Planning tab); they are only visible when editing the subscription and looking at the prediction pattern again. Bug 18365<https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=18365> and friends made it easier to handle discrepancies in the schedule. An occasional irregularity could be resolved that way. Would it be useful to define recurring irregularities in terms of the serial frequency chosen? If it is month, we could allow the user to select one or more months to skip? Same for weeks or days. (Year seems less interesting.) Doing this would replace selection of irregulars in the prediction pattern. If so, how should we handle 'special' frequencies like 1 per 3 months or 3 per month btw? Skip all in e.g. July or refine with skip second in July etc.? It seems to me that we should make the irregularity info more visible to the user too on Serial collection form. == If you are working on serials and have some thoughts about this, please share them on the Bugzilla report. https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=17656 Thanks, Marcel
