#Incompatible and #Context: Occurs if you try to include objects from 2 Queries/contexts which does not have any relationship or tables which are not linked then #Context appears in case of measures and #Incompatible appears in case of dimensions because it has a non-existent calculation context.
#Incompatible in case of single data provider: may be having multiple sql queries in one data provider that is if you include objects from different contexts.
How do you resolve #Incompatible? By creating a detailed variable for the incompatible dimension and associating it with the merged dimension, and using this variable in the report.
#Computation: Occurs when a slicing dimension specified in the Relative Value () function is no longer available in the calculation context. I.e. object might be deleted or renamed.
#Div/0: Occurs when a formula tried to divide a number by zero.
#Multivalue: Occurs when you place a formula that returns more than one value in a cell that outputs. Or if a single cell is trying to display multiple values. Or occurs when you don’t set sql aggregate functions for a measure object in universe designer.
Ex: [Revenue] ForEach ([Country]) returns #Multivalue because country might have multiple countries like India; US.one cell cannot display revenue for 2 countries.
If report is broken into section on country the formula is correct.
#Overflow: Occurs when a calculation returns a value that is too large for Web I to handle.
#Partial Result: Occurs when we set Query controls in universe designer.
#ToRefresh: Occurs if the measure object has projected function “Database delegated”.
#Syntax: Occurs when a formula references an object that no longer exists in the report.
