TRX is an abbreviation of the term Transaction Processing. When sales orders are shipped, a transaction is recorded for each item on the shipment. Purchase order receipts create transactions showing the receipt of items. Work orders, projects, and point of sale transactions also create item transactions within the Inventory module. These transactions include the date, document (sales order number, purchase order number, etc.) quantity, cost, etc. of the transactions. All of these transactions get recorded in TRX and saved for audit trail purposes.
