Error: Both left and right inputs must have connections

[Alteryx_KB]

Environment Details

• Alteryx Designer
  • All Versions
• Join tool
  • AMP error text: Missing Incoming Connection, Both left and right inputs must have connections.

Cause

One of the input data streams to the Join tool is missing, after a successful run; i.e. the tool was previously configured and contains the metadata from each input stream, yet the data stream is now disconnected. 

Resolution

Reconnect the data stream to the empty input anchor.

Hi, I am trying to implement a workflow , where multiple attributes are validated and final data is displayed in a single o/p file. I have broken down comparison of every attribute to its own individual workflow(Inside a tool container) based on requirement, but i run into error if i try to disable any of tool containers (my project has 19 attributes so 19 tool containers). Is it possible to implement a solution around this. I want to give end user option to choose attributes to be validated.

I tried using dynamic select but haven't figured out the solution yet.

Thanks in advance!
