Currently, there is a "quota" limitation on spreadsheet data sources. I believe you start getting "quota exceeded" errors if a spreadsheet is larger than 25mb. I am aware that this limit can be changed via the API, but I would like to suggest that this limitation should be allowed to be altered by an administrator in the QMC.
I had a support case for the issue, and it's not related to the message size quota. It's an actual file size limitation, but it only seems to throw an error when you try to duplicate an application that contains a data file (spreadsheet) larger than 25 mb.
I'm in the US. I did speak to Qlik support about this, and they verified that there is a limit of 25mb for spreadsheets and it will throw an error "quota exceeded" when you try to duplicate an application that contains spreadsheets larger than 25mb.
Sorry my bad, I meant duplicate, the duplicate app will do the same thing at the file level, the duplicate is then
placed in your My Work stream, as I say I have move big apps around Export/Publish/Duplicate, this really sounds like a server admin issue that I cannot put my finger on, I'm not on site at present so cannot check this out.
Is this a production app you are trying to duplicate ? I was going to suggest if it was not a prod app, then do a limited load to reduce the size of the app then duplicate it. Or try an export and then import it which will be the long way round to a duplicate, not ideal but it will get you over the line until your admins sort the issue out.
As I say, what have Qlik said to you , usually they are pretty quick to respond to these types of server issues.
