I can't find "sn_flow_designer.max_action_vars" and "sn_flow_designer.max_script_variables" .

Hi there!!

I am currently looking to set up more than 20 inputs in a custom action in the flow designer.

However, I have read on the net that to set more than 20 inputs, I have to change the value of

 "sn_flow_designer.max_action_vars" and "sn_flow_designer.max_script_variables".

(Location: System Properties [sys_properties] table)

I have searched for "sn_flow_designer.max_action_vars" and "sn_flow_designer.max_script_variables"

in PDI , but I can't find them.

Which "sn_flow_designer.max_action_vars" and "sn_flow_designer.max_script_variables" can be changed here?

Hi there,

That's correct, out-of-the-box these properties don't exist. The default used value though is 20.

If you want to change this value, then you would need to create these system properties. 

If my answer helped you in any way, please then mark it as helpful.

These are just system properties, you can just create them.

Name = sn_flow_designer.max_action_vars
Value = the value you are after
