delivery schedule

Hi All,

Can anybody tell how to set default delivery date format( e.g Month or Day) in Delivery Schedule( T Code ME 38).

In me38 I have to express the delivery date data is in workdays, there I need to enter date category in the day format.

I have to enter the date like this

Delivery date in workdays -within 5 days

If I am selecting format as D or T and entering 5 (which is 5 work days), I am getting the following error

Date 5 period T is not valid

Message no. VD345

Diagnosis

The format of the date entered is invalid.

Procedure

Check the period indicator and the date entered and whether they match.

Please help and guide
