Delivery document date

Hi All,

I have one question related to Delivery Date. Is it possible to have “Delivery document date” or “Actual GI date” as “Planned GI date”. For example, Delivery document# 1801 was created on 5^th March 2012. Planned GI date is coming as 15^th March 2012 after considering the Delivery Scheduling & predefined time estimates for delivery activities such as picking and packing).

So my question is: can we change the Plnned GI date as 5^th March? System is not allowing to change it manually. Please let me know if you need further informations.

Regards,

Mayank
