Executive Business Development Question:
Explain fantrap in Business Objects?
Answer:
Actually FAN TRAP is a problem that occurs in Universe Level. Loop occurs while we design the universe.
Two Types of Loop Problem:
1) FANTRAP PROBLEM solved by ALIAS METHOD:
Definition: Two One-to-many table link eachother is in turn linked another one-to-many table.
2) CHASM TRAP PROBLEM solved by CONTEXT METHOD:
Definition: Two Many-to-one table converges on one single lookup table.
Loop can be detected while INTEGRITY CHECK is done. An option is there as "Check for LOOPS" available. By "Detect Loop" we can choose what to be applied for solving the loop.
FanTrap: resolved by alias. Two one-to-many joined table linked each other and in turn linked to one-to-many table.
