Day end processing error while posting PO Receipt

Hi,

While posting PO Receipt getting this error message "Description: Purchase Order Audit Line  Invalid characters put to field 'Tax Recoverable Amount 2 Sum'.

Description: Day End Processing could not process all transactions."

There are 2 line items and the problem is only with this items. For other items PO receipts posting fine. Same error came while posting purchase order entry and I just removed UOM & Tax for this item master and then added back then tried posting it was ok, now again its repeating with its receipt. I tried DBSPY & RVSPY but couldn't figure out exactly what's the cause. Pls help
