Decimal space problem in Condition value of Import PO

Question

Dear All,
In PO the condition value found to be 0.00.
When the problem explored,we find only 2 decimal places appears for the value.
If the value is 0.0021,it appears as 0.00 only due to decimal space given in KOMV(structure) against KWERT field is 2 decimal space only.
Can we increase the decimal space?If we increase to 4,what will be the effect or NO effect?
Please advice.
Regards
