NPrinting reports include outdated data until connection metadata is refreshed

• NPrinting 17 and 18

• You have NPrinting reports retrieving data from a QlikView or Qlik Sense document.
• You reload the source document on QMS or QMC
• When you run the NPrinting reports, old data is still displayed.

Qlik NPrinting automatically uploads metadata when a new connection is created. However please note that NPrinting Metadata must also be updated whenever you change the data structure or content of QlikView documents or Qlik Sense apps connected to Qlik NPrinting. This ensures that Qlik NPrinting is aware of these changes. This is documented under the Help site under Reloading connection metadata.

When column data is removed or added to a chart, this must also be reflected and updated in your NPrinting Report Template editor. In this case you would need to manually update any tables in the NP template editor by right clicking on each one individually and click 'update' from the context menu.

When NPrinting ends a schedule, some connections to the QlikView documents used in the last execution are kept open in order to optimize the next executions. The idea is that it will be not necessary to re-open the QlikView document to import the data, and this saves time.
Unfortunately, changes in the applications are not detected if this is not closed and re-open, so you can get old data.

There are four possible solutions:

• Reload the NPrinting metadata (manually or using an NPrinting schedule trigger on the NP connection) after every QMC and or QMS qvw or sense app reload. This will refresh the connections.
• If using QlikView, use a QVP connection as it is described in the document attached.
• Use the workaround attached to this article QlikView Only ( .pptx file that can be retrieved when logged in to the Support Portal)
• Upgrade to NP 17.4 June 2017 or higher in order to leverage the schedule trigger on each connection to schedule metadata reloads as needed. (NOTE: this feature is only available in NP 17.4 June 2017 release and following versions going forward).
