what is the transaction types used to calculate inventory opening balance

AI generated answer (using internal Slack threads):

The transaction types used to calculate inventory opening balance in NetSuite are typically Inventory Receipt (IR), Inventory Adjustment (IA), and Inventory Transfer (IT). These transactions directly impact the inventory asset account and are used to track the inflow and outflow of inventory items. However, it's important to note that any transaction that posts directly to the inventory asset account without an item reference, such as Journal Entries (JEs), can also affect the inventory balance. This is often seen when vendor bills are entered with the inventory asset account on the expense line but no items. This is generally not recommended as it can lead to discrepancies between the balance sheet inventory asset and the inventory valuation summary report. In addition, sales transactions like invoices can also affect the inventory balance. These transactions typically debit the Cost of Goods Sold (COGS) account and credit the inventory account. To accurately calculate the inventory opening balance, you should sum up the quantity of all posting transactions from the inventory GL account for each item up until the date you're calculating the opening balance for. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
