in the related records of an assembly, i see two assembly build one in positive and another one in negative

AI generated answer (using internal Slack threads):

In NetSuite, when you see two assembly builds for the same item, one in positive and another one in negative, it usually indicates that an assembly item was built and then unbuilt or disassembled. When an assembly build transaction is created, it increases the quantity of the assembly item and decreases the quantity of the component items. If you later decide to unbuild or disassemble the assembly item, NetSuite creates another assembly build transaction but with negative quantities. This is to increase the quantity of the component items and decrease the quantity of the assembly item. This is a standard behavior in NetSuite and is designed to maintain accurate inventory levels. If you see a negative quantity in the "Used in Build" line field in an assembly build, it could be due to the disassembly of the assembly item. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
