Dynamics Ax 2012 - AIF - Number of decimals

Hi,

I have an outbound port defined on AIF and I have realiced that all my real values are with 2 decimals. It was ok until the customer required 3 decimals for a qty field.

How can I generate the output XML for the value with 3 decimals? The EDT of the field has a number of decimals with automatic value and I dont want to modify this value on the EDT because is a standard QTY field as SalesQty or PurchQty.

Thanks
