When I end a workflow with the “Data to Report” node to access or create the reports workflow editor how do I create multiply graphics and reports. Add additional “Data to Report” nodes?
You can only build one report per workflow using BIRT. But you can create all you need in a single report and then split the report e.g. use this free online tool to split PDF:
If you want multiple reports from a single workflow, then the other option is a workaround whereby you call a second ‘slave’ workflow which generates a report from the main workflow.
There are a few topics on the forum where this is mentioned, in particular this one has an example:
OK, attached are two workflows. Save them in the same folder in your KNIME workspace.
Report_Workflow.knwf (12.3 KB) generates the report (in this case, a very very simple report!), and is called by executing the second workflow:
Report_Name.knwf (9.6 KB), which runs it, and saves the report to whatever location you put in the Table Creator node in it.
If you are running on a KNIME Server, then replace the Call Local Workflow with a Call Remote Workflow node
Also, this one might be useful:
I have a large dataset with has countries and accompanying data. I am trying to dynamically get KNIME to create individual reports for each country.
Based on looking at past posts, I have deduced that the system should look like this but I can’t quite make it work:
Loop to filter by country
Use call remote workflow to run the report and extract it onto .xls
I can’t seem to find the right filter that will run the filter through the unique values in the country column
