Planned Calendar : Delivery Date error

Folks,

I have run into a dead end and I need your assistance ...

The scenario is

1. For 'material A', I am maintain a planning calendar in MRP2 view(in this case let us say '001:Monday') with a Planned Delivery time of 6 days in the same MRP2 view

2. I run a 'md03' for that material ( I would say I am doing a MRP run for material A)

3. I save and check my Purchase Requisition and my delivery date is showing the 6 days afer today, i.e.the the day MRP is run.

The delivery date needs to pick up Monday as the delivery date.Can someone please provide a solution?

Cheers,

C
