how to make mandate a line level item field on a sales order?

AI generated answer (using internal Slack threads):

To make a line level item field mandatory on a Sales Order, you can use either a Workflow or a Client Script (CS). If you choose to use a Workflow, you can set it up to apply only to the Sales Order record type. This way, the field will be mandatory only for Sales Orders and not for other record types. However, keep in mind that using a Workflow might slow down the Sales Order processing if it has to check every item. If you choose to use a Client Script, you can write a script that checks if the field is filled in before the record is saved. This script would be triggered on the 'saveRecord' event. If the field you want to make mandatory is a custom field, you could also use the 'mandatory' checkbox in the field setup. However, this would make the field mandatory universally, across all record types where it is used, not just Sales Orders. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
