Basically, what is a template.....a set of object frames 
placed in a way that suits most of the requirements of day 
to day office work.

To create a template, u can either develop a variation from 
the existing templates of the Crystal reports Suite or open 
a saved report, , in the new report u r creating, click on 
the template expert and choose template from existing file.
the template, that is the object frames and not the data 
will be copied to the new report u r developing.
even , now u have the liberty to make changes, and save 
them for future use as template!
So u can literally create as many differnt types of 
templates as u like through all the templates already 
available or the reports u created from teh scratch.

A section expert is used for the entire section, it could 
be the details section or the header section. Once you 
change the settings in the section expert it can be seen 
through out the section. if we want to make sure that a 
specific data has to be displayed in the entire setion , 
then you can write a formula for that in the section expert 
which will work good for all the sections.

Group: To change the group using chang group option. or 
goto the group expert we can change the group.

Parameter: To set the parameter order. To change the

There are two types of subreports
 a.Unlinked Subreport
       ie the subreport doesn't depend on the main report 
at all.
 
 b.Linked subreport

  A linked subreport is handy when we need to display 
related data elements from more than one database table on  
a report.

There are three types of subreports

c.On-Demand Subreport

If your report has a section that handles a large number of 
records, you can put that section into an on-demand 
subreport. An on-demand subreport appears as a hyperlink in 
the primary report. When you open the primary report, no 
data is retrieved for the on-demand subreport until you 
drill down on the hyperlink.

You cannot insert any subreport in a subreport

No. in Sub Report we cann't insert subReport.

Subreport is like the main report however the values from 
the subreport can be passsed to the main report. If we wish 
to link the subreport to the main rport then it is called 
as a 'Linked Sub report' else it is a 'Un linked Sub 
report'. Any number of sub reports ca be placed in a main 
report. However the maximum number being 256. In practise 
you would never have so many sub - reports in a main 
report.

You can create report types like

1.Form/Layout
2.Summary
3.Listing Reports

Moreover you can create your own report format and make it 
as template for your other reports in Crystal.

1.Form/Layout
2.Summary
3.Listing Reports
4.mail
5.drilldown

Use the OLAP Grid command to insert an OLAP Grid into your
report. When you choose the OLAP Grid command, the OLAP

forms of OLAP (Online Analytical Processing) and
multi-dimensional data storage and access systems.

Advantage of having Crystal report:
   Say if you have billions of data and you need to 
group/sum the data then Crystal reports is the tool
to use to do the calculations and other business login in
easy and professional way.
  You can provide drilldown options, hyperlinks to the 
data, alert the user based on the data, pictorial view of 
the data using Graphs and all these thing you can do it on 
fly.

Disadvantage of using ur own reports:
   You need to code for each and everything in your report
and which needs more time.
