How To Fix KB502 - Statistical key figures of different types cannot be added together

SAP Error Message - Details

• Message type: E = Error

• Message class: KB - Controlling: Reporting

• Message number: 502

• Message text: Statistical key figures of different types cannot be added together

What causes this issue?

You have tried to add together statistical key figures of different
types. Fixed value key figures, such as employees, cannot be added
cumulatively over the fiscal year. Other statistical key figures, such
as telephone units, are added to form a total for the year. If only one
of these key figure types exist, you can create a total for the year
provided the units are the same.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Since you cannot create a total in this report, you must suppress
totalsformation for statistical key figures.
There are two ways to do so.
Change the definition of the report. In the "Environment" menu, use the
function "Define reports". Here you must select "Report" and then
"Change". You can now access the the row definition directly. You
suppress totals formation for rows with statistical key figures. To do
so, set the totals level to 1-.
In general set maintenance, you can delimit the row with the
statistical key figure. Instead of the definition "Display all stat.
key figures", you can change the definition to "Display statistical key
figures Employees 1 and Employees 2". Totalling then takes place
through these two key figures only. The definition in general set
maintenance must afterwards be assigned to the report.

• What is the cause and solution for SAP error message KB502 - Statistical key figures of different types cannot be added together ?

  The SAP error message "KB502 Statistical key figures of different types cannot be added together" typically occurs in the context of cost center accounting or internal order accounting when you attempt to aggregate or sum statistical key figures that are of different types. Statistical key figures are used in SAP to represent non-monetary values, such as headcount, machine hours, or other metrics that can be used for allocation purposes.
  Cause:
  The error arises when you try to add or aggregate statistical key figures that are not compatible. For example, if you have one statistical key figure representing headcount and another representing machine hours, SAP will not allow you to sum these figures because they represent different types of data.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Key Figures: Review the statistical key figures you are trying to add together. Ensure that they are of the same type and represent similar metrics. If they are different, you will need to handle them separately.
  
  
  Use Appropriate Aggregation: If you need to perform calculations or aggregations, ensure that you are only aggregating key figures of the same type. For example, sum all headcount figures together and all machine hours together, but do not mix them.
  
  
  Adjust Your Reporting or Input: If you are generating a report or inputting data, ensure that the statistical key figures you are using are compatible. You may need to adjust your data entry or reporting criteria to avoid mixing different types.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more information on statistical key figures and their usage. This can provide insights into how to properly configure and use these figures in your reports or calculations.
  
  
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal SAP team for assistance. They may have additional insights or solutions based on your specific configuration and usage.
