Changing field display, but not value

Hello Everone,

I'm trying to use the my UDO Lines Matrix columns for Price Field with a change from what they really need to be saved on the DBDataSource.

In the "Price" Column i want to display the price including the currency, but i need them to be saved in serperated fields (just like in the Sales Documents). I think that in the Sales Documents there is a use in a neutral UserDataSource for these columns. Is that the solution? if yes, is there any way to connect them automaticly to a DBDataSource field, or do i need to do that manually?

Thanks & Regards

Mosh
