rounding Setup or Default

Hi;

Please guide to understand what is the rounding setup defined in Procurement and Inventory module in keeping amount. I am facing problem in reconcilling PO and AP accrual values.

Received Inventory (stock) as per defined in PO (same quanity and amount) and in the same way recorded Invoice using matching option, but somehow difference in decimals is appearing in most of the cases (local currency and foreign currency). Please advice how to identify the problem so that it can be handled.

Regards

Mashood
