How can I set a field mandatory before load?

@battk thanks, but it didn't work beforeLoad and if you set it in client script it will ignore it.

you can try sharing your code, but you dont have any other choice in the beforeLoad

It's a custrecord field

you can try sharing enough so that i can recreate whatever you are doing

@battk const rate = ctx.newRecord.getField({fieldId: ""}) rate.isMandatory = true

go though the documentation i linked

Not view only?

in more technical terms, the serverWidget's isMandatory has a setter function associated with it

Thanks

so the working way was?:

scriptContext.form.getField({fieldId:"the_field"}).isMandatory = true;

True
