Set Select Box variable value in onChange script

[dp11]

Below is a screenshot of an onChange script where I am attempting to set the value of a Select Box type variable based on value selected in a Multiple Choice type variable.

Desiring the below:

1) When osc_node_res_action (Multiple Choice type) value is 'new'
        osc_node_res_magnetic_flag (Select Box type) should be set to 'Yes'

2) When osc_node_res_action (Multiple Choice type) value is 'modify'
        osc_node_res_magnetic_flag (Select Box type) should be set to 'No Change'

I tried using the setValue method first but that had no effect. Then I tried the addOption method which works on the catalog form. But after item submission if I simply refresh the RITM form, there is an alert indicating 

"Changes you made may not be saved" with choices to Leave or Cancel.

Also, the value of osc_node_res_magnetic_flag (Select Box type) in the RITM's Variable tab does not change as desired.

NOTE: I have experimented with unchecking the "Applies on Requested Items" and "Applies on Catalog tasks" checkboxes and still the above two behaviors are the same

Or is there any other way I can effect the desired value changes?

Thanks!

Hi @dp 

I think we can achieve through Catalog UI policies,

Have you tried it ?

Thanks,

Well, found out that the issue was due to a conflict of the onChange script with a UI Policy on the same field. Now, am setting the value using the Script field in the UI Policy itself instead of in the onClient script and that  works
