Here's some thoughts:
- G/L Journal Entries were made directly to the G/L Inventory account(s), independent of your subsidiary modules (e.g., I/M, S/O, P/O, etc.).
- Something was posted in the future.
- Valuation changes were made in the I/M module but no related G/L entries occurred.
- Dug up this old FAQ: Why is the Inventory Valuation Report total different from the General Ledger Detail Report total for the Inventory account number?
The Inventory Valuation Report is a real time report. It includes all the transactions that have been entered into the Inventory Management system as of the moment the report is printed.
The General Ledger Detail Report prints transactions based on the posting dates. Normally the General Ledger Detail Report will be printed as of a specific date and it will only include transactions posted up to that date.
You can not print the Inventory Valuation Report as of a specific date because it will always include all transactions entered into the Inventory Management system. As an alternate to the Inventory Valuation Report, the Inventory Trial Balance Report can be used to reconcile the current period of the Inventory Management Module to the General Ledger Module.
