UOM Changeable Flag to Yes DACSAUCOE

SOLVED

Hello,

Im working with different UOM on Stock and Sales levels. I have done the UOM conversions but the sales invoice does not allow me to use a UOM different to the default on the Product Master. Could it be the Changeable flag on the Product Master UOM Tab which is not ticked ?

I tried to set this field DACSAUCOE to yes but the system would not allow this. Is this flag controlled by parameter ?

Thanks as always
