SAP BusinessByDesign

1. Go to Purchase Requests and Orders work center
2. Select Common Task New Purchase Order
3. Enter all necessary details
4. Under Item Details, enter Delivery date as 31.12.9999
5. Error: End date must be after start date. Enter a new date for the delivery date, service period, or expense period for the selected item

When a Delivery Date(mapped to Start Date) is entered by user, we derive the Delivery End Date by adding 1 day to it(Considering
 the Delivery Period of 24 Hrs).

In the reported usecase, since the Start Date itself is selected as 31.12.9999, the End Date calculation value is discarded, and the said error is thrown on Check.

Enter a realistic date. Maximum date can be 30.12.9999
