Tax/Service Date on Voucher/Invoice

Hi,

currently we are not managing the Service Date (DSVJ), so basically this is always equal to the GL Date.

What the customer want is to have the payment terms to be calculated based on the DRQJ coming from the Sales Order / Purchase Order.

We are thinking to customize the valorization of Service Date on F0411/F03B11/F0911 using a date calculated base on the Requeste Date (DRQJ) of Sales or Purchase Order.

There's any constrain to use the Service/Tax Date? There's any impact on the GL / Invoice / Voucher?

There's any validation on the Service/Tax Date?

Thanks
