Handline #Multivalue Error in SAP BO Webi report

This error occurs when your formula returns more than one value and WebI report doesn't know how to aggregate those values. The #MULTIVALUE error can appear in several scenarios −

• #multivalue in aggregation − When a formula returns multiple values without proper aggregation
• #multivalue in breaks header or footer − When break sections contain non-aggregated multi-value data
• #multivalue in section level − When section calculations encounter multiple values

Understanding the #MULTIVALUE Error

The error occurs because WebI cannot determine which value to display when multiple values exist for a single cell. This typically happens when there's a one-to-many relationship in your data that hasn't been properly handled.

Example Scenario

Consider an account number that is associated with multiple order numbers. When you try to display order numbers at the account level without aggregation, WebI throws the #MULTIVALUE error because it doesn't know which specific order number to show −

#MULTIVALUE "Multiple Order Numbers for the same account number"

Solutions to Handle #MULTIVALUE Error

You can resolve this error by using appropriate aggregation functions based on your business requirements −

• Max() − Returns the maximum value from multiple values
• Min() − Returns the minimum value from multiple values
• Sum() − Calculates the total of all values (for numeric data)
• Count() − Counts the number of values
• Avg() − Calculates the average of multiple values

Example Solution

Instead of using the dimension directly, wrap it with an aggregation function −

=Max([Order Number])
=Count([Order Number])
=Sum([Order Amount])

Choose the aggregation function that best suits your reporting needs. The #MULTIVALUE error will be resolved once WebI knows how to handle multiple values through proper aggregation.
