There are 3 sections for Writeback settings.

  • Destination contains configuration settings for writeback data output and writeback operations.
  • Audit Columns contains settings to enable and customise an audit trail.
  • Reload settings configure when writeback operations are performed. 

In this article we're going to focus on the properties for the Audit Columns, and Reload sections. If you need further information on the Destination section, you can find a link to the article here. You can also find more information on Writeback Operations in the article here.

Audit Columns

If you would like to build up a record of your input form changes, you can use the Audit Columns section to set this up. There is a Standard audit trail set as the default (Figure 2), or you can choose None to disable the function completely. 

You can select the Timestamp format which you'd like to use from the dropdown, or use the Qlik Sense expression editor to customise the Timestamp label and User label

Figure 2: Audit Columns

You can choose to customise the Timestamp format of your audit trail, by selecting the Custom option from the dropdown. The Timestamp custom format will be displayed, and you can use the Qlik Sense expression editor to enter the format you need. (Figure 3).

The Reload section (Figure 4) contains settings relating to when a reload action is performed on the writeback table. You can choose from 

  • No reload - No reload when writeback is called. 
  • Reload app (default) - The app is reloaded when writeback is called, overwriting any existing data. A potential use case would be before generating the latest version of a report. 
  • Partial App Reload - The app is partially reloaded when writeback is called, so new values are added without overwriting any existing values. A potential use case would be for refreshing or reloading data in dashboards. If you'd like to learn more about partial reload functionality, please see the article here
