Anyone know if there is a way to mass update or script to update subsidiary for child matrix items? It appears you can only do via UI but we have too many parent SKUs to update as such. Thanks in advance for any help/feedback.

Have you tried a CSV update? You (should) be able to Update with INternal ID and the new subsidiary structure. If you have transactions in a Sub you will have to retain that as one of the Subs.

@Netsuite Tragic yes, we have tried CSV & with scripting but it does not update the children subsidiary. There are no transactions as this is new but a change to subsidiary after initial setup. Its over 1100 parents that have children so doing via UI would not be efficient. Thank you for your response 🙂
