I have created workflow_1 to do calculations, which contains ‘Data to Report’ and ‘Image to Report’ nodes. Workflow_2 uses ‘Call Local Workflow (Row Based)’ to create workflow_1’s report via ‘Binary Objects to Files’. Nothing special so far.
I have be asked to expand workflow_2 to be able to create as much reports via workflow_1 as an input file contains ids. So I would like to separate the ids in workflow_2, send each id to workflow_1 to create a report with this id, and merge all reports in one pdf file.
Do you have any idea how to help me? I am limited to KNIME Analytics Platform without access to KNIME Server.
Probably Group Loop Start node will help to separate ids. Here is topic you can check which include example:
If you create multiple reports (multiple PDFs) I’m not sure you’ll be able to merge them in KNIME into a single PDF report so seems you should send all data into wf1, do separation there (same calculation for different ids within loop) and send that data (after loop end) to report to have only one PDF.
