Syntax error: As the name indicates, check the syntax of 
the formula used.

Multivalue error: Use some aggregate functions such as Max
(), Min(), Sum(), etc... (but that mainly depends on the 
requirement)

#Error: This can be solved by checking the formula. For 
e.g. If one has a UserResponse function like this.
UserRepsonse("DP1","Enter a date") and if the date format 
id mm/dd/yyyy, then the following formula will lead to 
#Error.

ToDate(UserRepsonse("DP1","Enter a date"),"dd/mm/yyyy")

This can be solved by using "mm/dd/yyyy" instead 
of "dd/mm/yyyy"

Computation error: This error occurs if we don't have a 
required object in the block. Sometimes we don't want a 
particular object to be visible. In that case, to avoid 
computation error, just include that object in the block 
and hide it.

Objects not compatible: In this case, try creating detail 
objects and associate them with the necessary dimensions 
and instead of placing the objects, place the newly created 
detail objects.

Multivalue Error: while connecting from dimension to fact 
it should always be one-to-many only, if this logice is 
handled improperly we may come across this error.

Objects are not compatible: This error occurs when 
connecting more than one dataprovider,datatypes of both the 
objects(dimensions) to be joined or linked to produce a 
single report should be same.
