What is supported by ExtendInsights?
Updating matrix items
It is possible to edit standard and custom fields for matrix items in the same way you edit them for standard inventory items.
Simply create an item template (inventory or non-inventory), load the items via data filter, saved search, or refresh, and then make changes to the fields. When complete push the data back to NetSuite via update.
Using Matrix Items on Transactions
When adding a matrix item to a transaction simply add the child item.
For instance, if you are selling a blue sweatshirt you would add the actual child item to the transaction, ie sweatshirt - blue.
