Set default value of line field to be the applied to transaction link

AI generated answer (using internal Slack threads):

Based on the conversations, it seems that you want to set a default value for a custom transaction line field to be equivalent to the quantity in base units. However, a default value might not be able to accomplish this as it is set during the record load process and at that point your line items won’t be entered so NetSuite has nothing to calculate. You would need to add a script or workflow that calculates the quantity into the base quantity during the item entry or record submit process (so after they click save). A workflow might be able to do this but would have to test if we can do a units join to get the conversion rate. A script should be fairly quick and easy to put together. Also, if you want a transaction line field’s default value to refer to an item custom field, you can do so by going to Transaction Line Field > Sourcing & Filtering > Source List = Item > Source From = Item Field. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
