RE: How to set a script parameter?
There is a way to set a script parameter in suitescript that is not documented.
Does anyone know about this?
Script Deployment is a documented record type : https://system.netsuite.com/help/helpcenter/en_US/srbrowser/Browser2019_2/script/record/scriptdeployment.html
You can set the script parameter values just using standard N/record operations if that is what you are looking for.
(Assuming the script parameter is set up to Store Value)
