--- Comment #13 from Katrin Fischer  ---
Rereading this I wondered:

Maybe we should keep the first issue as is, but rename it "Start issue" or
similar and have a new and different field, perhaps linked to subscription
history, for the first issue published/available in the library if there is a
need for having this information? 

My use case was this:

The subscription start date could have been at the beginning of the year or
even years ago (most here are renewed automatically) and I don't really care
about this date for the predictions.

The "Start issue" would be the one I start predicting with.

The "historical" first issue  would be the first one in my library's
collection.

... and now I wonder if this isn't what the subscription history fields are
already supposed to be used for:

- Check manual history
- Go to the subscription
- Edit the manual history
- Change the subscription start date.

It won't change the start date when editing the subscription, as these fields
are all stored separately in the database. So maybe the solution is ultimately
to make the history more accessible and maybe add any additionally needed
information there?

 Status|Patch doesn't apply |Failed QA

--- Comment #12 from Myka Kennedy Stephens

I like Nick's solution. Give the user a choice (radio button) to generate
issues based on date of first issue or subscription date.

Scenario: A library acquires a run of a serial that started in 2000. The back
issues are already bound together and ready to be added as items. The library
also starts a subscription to continue receiving new items beginning on January
1, 2020. The library wants to preserve the information that the first issue was
published on January 1, 2000 but the predicted issues only need to be generated
from January 1, 2020 and on.

In this scenario, it makes more sense to base a prediction on the subscription
start instead of the date of first issue. Our library workflow would use
acquisitions or simply add the back issues as items to the biblio instead of
receiving them through the serials module -- especially if they were already
bound together as volumes. 

(I'm also going to change the status to 'failed QA' since I incorrectly used
'patch doesn't apply' when I tested this back in October.)

Sounds good to me! I'd also be interested in being able to compare to
understand the differences pointed out here better

I think the issue here has been for bringing in subscriptions from another
system, so you are setting the first issue to the first one held, but then
adding the start date and wanting to see the issues from that date forward?

Either way, maybe a better solution is to preserve existing behaviour and add
an option (radio button) to select generating from the sub start date instead
of first issue?

Hi Myka, 

I think there might be some possible misunderstanding there:

>The expected/desired behavior is for Koha to start the prediction pattern 
>based on the subscription start date, listing the number of issues based on 
>the subscription length value. Koha will need to calculate the issue number 
>based on the numbering pattern and the first issue publication date.

In Koha, it was always documented: "In ‘First issue publication date’ you want
to enter the date of the issue you have in your hand, the date from which the
prediction pattern will start". See:
https://koha-community.org/manual/19.11/en/html/serials.html?highlight=first%20publication

So I wonder how changing that would affect libraries already using
subscriptions for a long time. At the moment, it could look something like this
for a lot of libraries:

Subscription start date: January 1st
First issue publication: March 15th (the first issue that was tracked when
starting to use the serials module)

It's possible to start in the middle of a prediction pattern - if you give me
an example that you are not sure about, I'd be happy to help and see if we can
make it work.

--- Comment #8 from Fridolin SOMERS  ---
Look at serials/subscription-add.pl _guess_enddate() :

} elsif($frequency->{'unit'} eq 'month') {
($year, $month, $day) = Add_Delta_YM(split(/-/, $startdate_iso), 0,
$numberlength * $frequency->{'unitsperissue'} / $frequency->{'issuesperunit'});

It is called by :

if($subtype eq "issues") {
$enddate = _guess_enddate($firstacquidate, $periodicity,
$numberlength, $weeklength, $monthlength)
} else {
$enddate = _guess_enddate($startdate, $periodicity, $numberlength,
$weeklength, $monthlength)
}

You see subscription start date is used.

 Status|Needs Signoff   |Patch doesn't apply

--- Comment #7 from Myka Kennedy Stephens  ---
Patch does not apply.

Here is the behavior I'm seeing in my test:

On master, without the patches from this bug applied:
1. Create a new serial subscription
2. Set the first publication date to a date in 2016
3. Set the subscription start date to a recent date in 2019
4. Set subscription length to 104 issues
** Also set frequency to weekly, numbering pattern to number beginning with
number 1
5. Test prediction pattern
** This results in a pattern that is for numbers 1-104 beginning with the date
of the first issue. The subscription start date is not included in the
predictions listed because it is beyond the 104 issues.
6. Apply patch
* Repeat steps 1-5
7. Test prediction pattern
** The results match the prediction pattern prior to applying the patch. When
you save the subscription, the issue expected is Issue No. 1 from 2016, not the
issue that corresponds with the subscription start date.

The expected/desired behavior is for Koha to start the prediction pattern based
on the subscription start date, listing the number of issues based on the
subscription length value. Koha will need to calculate the issue number based
on the numbering pattern and the first issue publication date. 

What is presently happening is the prediction pattern is based on the first
date of publication and length of subscription. This is a problem for libraries
that start a new subscription in the middle of a publication, need to predict
issues from the starting point of their subscription, and want to preserve the
first date of publication in Koha.

Hm, I am not sure this is right.

We always say that the date of the first issue matters, so if you set that to
15th and the subscription start date to 1st, the pattern should still use the
15th for calculating. That's how it always worked, it looks like this might
change that?

I think in JS "from" should be before the "to". They mean start and end dates.

During test plan, you may refresh browser cache (Ctrl+F5) after applying patch
to refresh JavaScript file.

Also, are you sure step 5 of your test plan is correct ? When I did it, I had
all 104 results in the prediction. The problem is that the issues' dates start
in 2016 (first publication) instead of 2019 (subscription start)
