Hi,
The financial amount of $29050 in inventory seems to be made up of the transactions posted on accounts 140211, 140231 and 140251.
This leaves the $400 on account 140221 and the -$550 in the inventory transactions.
Can you check whether all transactions for those items are properly posted, meaning that the transactions have been transferred to the GL and are not included in the subledger voucher not yet transferred form?
In addition, check account 140221 to verify that no manual postings have been made against this account.
What you should check in addition is that there is no ledger account that you missed in the selection of the total account that summarizes the balance at the end of your report.
Best regards,
Ludwig
