Creation of new field

Hi Alll,

Can you give me some help in this area---

Requirement is 5 decimals in amot which i cant go with std sap------(Ie. I cant go with chnages in global settings)

I want chnage the field KONP-KBERT) as with 5 decimal

if its not possible can we make one new field instead og KBERT like ZBERT with 5 decimal and we also should be ale to display only ZBERT not KBERT
