Netsuite return from Sales order doesn't remove or negate the lines

AI generated answer (using internal Slack threads):

In NetSuite, when creating a sales order, the line numbers may appear to skip around due to various factors. One of these factors could be the inclusion of tax lines in your search. If your search has 'tax line is false' in the criteria, it may cause the line numbers to skip. Additionally, if you are dealing with drop shipments, the line numbers may appear off. This is because NetSuite handles Item Fulfillments in a specific way. When you fulfill a quantity of 1, it is actually subtracting it. Depending on the filters you have, you may see multiple lines as NetSuite is taking in from one account and out from another. When setting lines on a sales order from a suitelet, it's important to use the

forceSyncSourcing

option with

CurrentRecord.setCurrentSublistValue(options)

. This is because

setCurrentSublistValue

is asynchronous, meaning it doesn't wait for the previous operation to complete before moving on to the next one. If you commit lines before they are done updating, it can cause the first line to be overridden with the second line. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
