what's the process to add a promotion to an item/sales order for orders created thru scripts in non dynamic mode?

AI generated answer (using internal Slack threads):

To add a promotion to an item/sales order for orders created through scripts in non-dynamic mode, you would need to use the

record.submitFields

method. This method allows you to update specific fields on a record without loading the entire record into memory. Here is a sample code snippet:

javascript
var salesOrderId = '123456'; // replace with your sales order internal id
var promotionId = '78910'; // replace with your promotion internal id

var id = record.submitFields({
    type: record.Type.SALES_ORDER,
    id: salesOrderId,
    values: {
        'promocode': promotionId
    },
    options: {
        enableSourcing: false,
        ignoreMandatoryFields : true
    }
});

This code will update the 'promocode' field on the sales order with the internal id of the promotion. Please note that this method will not trigger any business rules that would normally run when the record is edited in the UI. If you need to trigger these rules, you will need to load the record, make the changes, and then save the record. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
