PO quantities & prices

Hi all.

A serious problem...

We try to print PO layout with few quantities and prices base on decimal format which was defined to user master data (or vendor's land).

There is a problem with the format of these fields from different sites (Germany & Switz are decimals ',' and US is '.', for example).

Is there any function in SAP std to convert from format to another ? Any note ? Is this a BUG of SAP std?

Thanks all,

Rebeka
