In NPrinting 17.x, all filters are associated with a connection.
You can associate as many filters as you want with a single user and a filter can be associated with as many users as you like.
The filters will be applied to the objects in any report corresponding to the data source based on the connection specified in the filter.
In the Excel file used to import users and filters, in the Filters tab, Column C is used to specify the App name and Column E is used to specify the Connection name.
In the Users tab, Column N is used to specify filters associated with a user. Multiple filter names must be comma separated.
I think if your using global filter then as per my knowledge I don't think we have an option to specific the connection to choose for the filters/connection
I would suggest to implement the filters at individual chart level and try once .
The better approach is to handle all the complex logic in the Qlikview and just import the chart in NPrinting for representation
Sometimes it’s very hard to work with reports for several purposes and filters. I use some times the option the import user option. I only update the user filters. So I will run first my update user task. Afterwards I use the task to send the report based on the new users filters.
