Why row filter doesn't flow the variable to send email in KNIME?

Hi Team

Would like to know is row filter doesn’t flow with the variable ?

There is scenario where I have to add all the columns from DB query–>Row filer to send email and also there are few columns I need to add in HTML format .

Example 10 columns are there and 10 should flow to send email via Row filter variable and 5 should flow via html format to send email but I am not able to see them in send email though variable port .

Please let me know if you need any further details

It’s hard for me to understand the problem you’re having.

Most of the nodes in your screenshot haven’t been executed, so of course there are no flow variables created anywhere

You also haven’t showed us how the Row Filter node is configured, so we have no way of knowing what flow variables should be created by that node.

To add to @elsamuel words: as it’s currently configured, this only ensures that the Send Email node waits for the Row Filter to be executed.

Even if the Row Filter is configured in such a way that it generates the variable, the additional connection is not required since the variables are already part of the data pipeline and will also be available after the Table Row to Variable node.
