Hi Guys, I am trying to understand when a line unique key changes on a line in transaction? We were using line unique keys to map data from netsuite to external system and it seems like some operations update line unique keys of the line can someone explain what triggers an update on line unique keys or point me in the right direction? Also similar question for Line Id do they ever get updated? Is it better to use a combination of transaction internal ID and Line ID to keep things unique and updated?

line ids and line unique keys dont change

@battk Thank you! Are line Unique keys unique across Netsuite or say a LUK in JE could be repeated in INvoices?

line unique keys are unique, they will not repeat
