Report Template is a specimen for your future reports.
You create a report from scratch, say make it Master-Detail Report with charts, put your company logo, add some default colors(something like same colors your company uses for its documents, webpages etc.) & then save it as BO Report Template file.
Next time when you are creating new reports, & select use Templates option, your report saved as template will be listed in the box. If you select it, your new report will automatically use all color formats, & table-chart structures, logo....whatever you used in your template report file.
Advantage : 1 time devaelopment of display & structure format, for multiple reports use. i.e. Time Saving. No need of formatting for all standard reports.

We can do this in three ways:
1.alphabetical order-prompts will appear in alphabetical order
2.numeric order-prefix number and they will appear in numeric order
3.date order-prompts will appear date wise
it depends on the type we choose in prompt syntax
Cartesian product is getting incorrect results.
for instance if we have a cham trap or a fan trap n we din't solve them after checking the integrity also we get duplicate results of the same record ie nothing but cartesian product.
we have customer,orders,loans classes
orders for one product if the product_price is 150$ it will appear twice in the report due to traps bcoz of the cartesian product thats why to solve the cham trap we create context and in order to solve fan trap we create alias table.
Bo XI R2 versions is used in the BO dashboard work.
The difference between union and group is as follows:
★ Take two tables t1 and t2.
★ In t1 we have columns like a,b,c,d. and t2 has a,d,e,f.
★ Ao union means t1 union t2 i.e getting result from both tables i.e a,b,c,d,e.,f
★ Where as group performs on a individual column in a particular table.

As far as i know we schedule the reports through broadcast agent.
The DENSE_RANK function computes the rank of a row in an ordered group of rows. The ranks are consecutive integers beginning with 1. The largest rank value is the number of unique values returned by the query. Rank values are not skipped in the event of ties. Rows with equal values for the ranking criteria receive the same rank.
The DENSE_RANK function does not skip numbers and will assign the same number to those rows with the same value. Hence, after the result set is built in the inline view, we can simply select all of the rows with a dense rank of three or less, this gives us everyone who makes the top three salaries by department number.
Give me the set of sales people who make the top 3 salaries - that is, find the set of distinct salary amounts, sort them, take the largest three, and give me everyone who makes one of those values.
SELECT * FROM (
SELECT deptno, ename, sal,
PARTITION BY deptno ORDER BY sal desc
) TopN FROM emp
WHERE TopN <= 3
ORDER BY deptno, sal DESC
DEPTNO ENAME SAL TOPN
