What if a cartesian product pop up block appears when running a report. Does it give wrong values? How to solve this issue?

Answer:

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.

ex:-
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.
