Answer / babu
Traps are recives inacuurate data in report level, we need
to trace it by Manually.
A.Fan trap
B.Chasam TRap
A .If tables are joined as A(1:M)-->B(1:M)-->C we will get
more results than expected. through Alaias or Agg Awarenees
we can resolve. this is called as Fan trap.
tables B holds the Aggarigated values from A table then
only we will encounter fan trap is occured.
B. if tables are joined like B(m:1)<--A-->(1:m)C. This
CHASM trap can be resolved by executing separate query for
each measure and then merging the results.Use detect
context automatic tool to detect possible context in
universe and use them in order to avoid CHASM traps.
