I need to transform a sales order to return authorization with specific line items, not will all line items available on the sales order. Let’s say I have a sales order created with 3 items

• Item one with qty 2
• Item two with qty 1
• Item three with qty 4

this order fulfilled completely and billed. Now, the customer wanted to return Item two with qty 1 and Item three with qty 2, I want to transform (using suite script 2.0) my sales order to return authorization with only return items, I don’t want to include items that are not returned.

Returned items are available in an array;

const returned_items = [{ item: 'item two', qty: 1 }, { item: 'item three', qty: 2 }];
var returnAuthorizationRecord = record.transform({ 
fromType: record.Type.SALES_ORDER, 
fromId: orderId, 
toType: record.Type.RETURN_AUTHORIZATION,
isDynamic: true,
defaultValues: { 
customform: CUSTOM_FORMS_RMA.CREDIT 
} 
});
const lineCount = returnAuthorizationRecord.getLineCount({ sublistId: 'item' }); 
for (var i = 0; i < lineCount; i++) { 
returnAuthorizationRecord.selectLine({ sublistId: 'item', line: i });
// Do I need to first remove all line items and then add retuned items available in array 
returnAuthorizationRecord.removeLine({ sublistId: 'item', line: 3, ignoreRecalc: true });
// Or loop through each line and match with item, if item matches then update accordingly if not then remove from the list? }
returnAuthorizationRecord.save();
