"Call workflow action" functionality

KNIME Business Hub
1

Hello KNIME Community,

We recently migrated from KNIME Server to KNIME Business Hub and are experiencing issues with the “Call workflow action” functionality.

In KNIME Server, we could configure scheduled jobs to execute additional workflows based on the execution result (success or failure) through the “Call workflow action” option. This was configured in KNIME Analytics Platform by selecting “Edit Schedule” for a workflow, which opened the “Server Execution Options” window.

After migrating to KNIME Business Hub, we’ve noticed the following issues:

  1. While the “Call workflow action” option is still visible in the KNIME Analytics Platform interface, it doesn’t appear in the Business Hub web interface when configuring scheduled deployments.

  2. If we modify any schedule configuration parameters through the Business Hub web interface, any previously configured “Call workflow action” settings disappear from the KNIME Analytics Platform interface.

I’ve found documentation stating that “Call Workflow actions cannot be migrated to the Hub” and “require manual configuration”, but there’s no clear guidance on how to implement this functionality in Business Hub.

Is this functionality supported in KNIME Business Hub? If so, how can we properly configure it to ensure workflow chains execute reliably? If not, what alternatives are available to achieve similar functionality?

Thank you for your assistance.

Hi @jricgar ,
First of all, thank you for noting these.
Point 1. has been noted internally as an improvement.
Point 2. has been reported as a product malfunction and it will be evaluated for fixing in a future version.

In our documentation, the call workflow actions manual configuration just refers to configuring them manually in the Analytics Platform by editing the call workflow actions. This will also be noted as an improvment in our docs.

Aside from this, what could be worth checking out is deploying workflows as services on Business Hub, and calling them in other workflows by their endpoints.
We have a few examples of utilizing this in our Business Hub Deployments Guide.
