AI generated answer (using internal Slack threads):

Based on the conversations, it seems that you are encountering an issue with Fixed Asset Management (FAM) in NetSuite. The error you're experiencing might be due to the asset having a non-zero value. If the asset is considered "worthless" because you've already taken the whole cost as an expense, the entry just takes the asset and accumulated depreciation off your books. If you're trying to edit midlife assets, please note that certain fields are not designed to be edited. They can be updated via CSV if the asset has not started depreciating. If you have not started depreciating them, changes can generally be uploaded via CSV. If you're re-importing the assets, make sure to check the 'Run SuiteScripts' box during the import process. This is crucial for the correct setup of the assets. If you're not importing any depreciation history records, it's not mandatory, but it's recommended to run the 'Precompute Depreciation Values' script in the system setup. This script will create depreciation history "in the future". If you do not have any errors under 'Background Processions > Status', then your setup should be correct. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
