Some of the answers posted are good, but the real things to
do in order to improve the performance of the crystal
reports are:
- Server Side processing should be done.This can be achieved
by using the option PERFORM GROUPING ON SERVER.
-Using Indexes for faster data retrieval also improves the
performance of the reports.This can be achieved by using the
option USE INDEXES FOR SPEED.
- Instead of using the Formula Fields the other option
provided is SQL Expression Fields to improve the
performance. Using Stored Procedures is also very good
option since they are pre-compiled sql statements which are
permanently stored in the database where syntax checking
will not be done for each individual query.
-If you are using Sub Reports, then you can use the ON
DEMAND SUB REPORTS instead of normal sub reports. Since
using the normal sub reports will be a cost factor to
retrieve the data from the data source.
-Using Linked Tables with Indexes is the better option
instead of sub reports. Again it depends upon your requirement.
-Instead of retrieving all the records, its always
recommended to fetch only the necessary records using the
where condition.
They are still many points to be noted....as far as for
interview point.....providing these answers will surely
place you in a right position.

How many sub-reports can report can have?
Kindly Help for this Below Scenario, I am going to implement Power BI into our internal software. I’m familiar with the fact that each user can pay $9.99 a month to build and view reports but what I need to know is how can we embed Power BI into our application so that any users that log into our application can see the reports without the monthly fee. I’ve researched enough that it can be done. What I am not familiar with is how to do it or the pricing of embedding it into an application. I think they do pricing on how many renders you do or something. Would you be able to look into how we could embed it into our software and the cost?
