NPrinting Pixel Perfect report preview fails when columns are changed or removed

[Frank_S]

Pixel Perfect report is no longer previewing normally after modified source application QVW or QVF field columns and a preview error is generated

Note to object in the preview error as this will provide insight as to which chart to check for missing/removed/updated source app field columns.

Environment:

• Qlik NPrinting 

Configuration related:

• NPrinting reports do not automatically update according to these changes. Manual interventions is needed. Ideally your Qlik Sense app developer will have documented chart object changes including updated/removed columns.

Resolution:

1. Reload your NPrinting metadata connection used with this report before proceeding. This will ensure that the latest source QVF or QVW changes are cached in the NP connection.
2. Open the NPrinting PxP report
3. Navigate to the report field you have determined to have been changed 
4. Click the data binding dropdown in the field that needs to be changed and select the correct field mapping
5. Note: If the field has been removed from the source QVF or QVW app, remove this field from the report template entirely
