Bug: Manuel copy of multiple series low to high freq

Postby rousing » Tue Sep 15, 2015 5:59 am

Hi

Even with the latest patch a bug appears to remain when coverting multiple series manually from low to high frequency.
For instance copy - paste special - Litterman - Sum - is not preserved after the copy is completed and has to be set manually for each series afterwards.

Best regards

Rasmus:

If I try to reproduce your issue, I see two things:

1. When I copy multiple series (by link) from low to high, the selected frequency conversion is properly saved in the "Link Spec" tab of the destination objects.
2. When I copy by value instead, the selected frequency conversion (Litterman/Sum in your case) does not get saved due to the option not being available in the "Frequency Conversion" tab. This is by design as it was decided that any conversion options that required a possible indicator/rho values would not be preserved.

Is this the behavior your objecting to or are you seeing something else?

I copy by link and then the conversion settings are not saved on my side.
maybe it matters as well that the original series are links to a local eviews database

Rasmus:

I found a small problem when copying a db linked series object from one workfile to another (destination object is created as a formula instead of an externally linked object), but I wasn't able to reproduce your issue.

If I copy a linked object from one workfile page to another page in the same workfile (which is what I'm assuming you are doing), the new destination object appears as a page link object and if I open it and go to Properties, the "Link Spec" tab shows the correct Littermam-Average upconversion value I chose.

Can you provide more details on how exactly you are performing the copy, and whether or not it is with the same workfile?

Hi Steve

It is within the same file.
I have created a new file file with series linking to the FRED db and the same thing happens.
In the weekly sheet "w" I select the 4 series - right-click - copy - go to daily sheet "d" - right-click - paste special - paste as: "link" - merge by: "date with frequency conversion" - low to high frequency method: Litterman - match: "sum" - ok to all.
When I then revisit one of the series - double-click - properties - link spec - is now set as litterman - First

Hope this helps.

Thanks a lot for looking into it.

Best regards
Rasmus

Found it -- it's a bug with the Paste Special dialog that happens if you click on Yes All instead of Yes.

We'll get a fix in place as soon as possible.

Ok, this has been fixed. It'll be available in the next patch (probably Monday of next week).

and also thank you for finding the link copy bug between files, because this one I had also identified - but I just fetched freshly when starting a new file instead of copying...
