Some behavior of the crystal reports

Here are some of the behaviors of the crystal reports that can not be done by using it.

1.There is no option to display all the dates between the date ranges that passed through the parameters
2.If data is not available Bar chart will be empty, even axis will not be populated.
3.Cross tab reports is good choice for displaying categorized counts as vertical columns, but if any of the category is not present for a given time period, it will suppress the entire column even not leave a empty column and records marked as zero
For a case, we want how many applications received through internet and post .
we can get it as

Date       Internet      Post
01/01           5                2
02/01           3                6
03/01           8               12
04/01           6               10

if none of the dates having count under Post, the whole column will not be printed even the header
like this,
Date   Internet

01/01       5

02/01       3
03/01       8
04/01       6
4. Business objects enterprise repository server, There is an option to schedule the reports when to run(i mean the day,weekly, monthly), but there is no option for what date limts it has to fetch automatically.

That is weekly reports i can schedule to run on every sunday, but i can't specify the dates that monday to saturday data's it has to fetch.
