Answer / nareshkumar
A loop is a set of joins that defines a closed path through
a set of tables in a schema. Loops occur when joins form
multiple paths between lookup tables.
Loops can be solved by using aliases or contexts.

Answer / srikanth
Loop is one of the join path problem that arise when
designing the universe.While setting up joins between
tables,a closed path may occur between set of joins.This
scenario is called Loop.Because of this you will get
incorrect results in report.
You can avoid this problem by creating alias table or
Centext(define path for set of joins to follow)
