Problems SBO 2005 A PL 16

Hi Experts,

We're using SBO2005 A PL 16, have any problem:

1. If we filled sales A/R, why is delivery date able to fillthe date before field document date (e.g: delivery date is 27 Dec 2007 and document date is 28 Dec 2007). Why is happened?

2. If we use drag n realate, why is the date of filter not appear fully date. It just appear some dates (e.g appear date between 1 - 15 dec 2007)

3. What can we develope add on use by Delphi 7 ?

Please somebody help us about this matter.

Regards,

Adriant
