SAP Error Message - Details

• Message type: E = Error

• Message class: KG - CO-PA Planning

• Message number: 076

• Message text: Quantities with different units cannot be added together

What causes this issue?

This error occurs in the following situations:
Quantities in different units already exist for a profitability
segment.
The unit of the quantities already planned differs from that found by
derivation (usually the unit in the material master, if you are
planning a material).
You tried to aggregate values with different values in the unit field.
This happens in the following situations:
The unit field was not entered in the general data selection or in the
rows or columns of the planning layout. (The unit as an attribute is
not sufficient!)
You selected "Summarize" for the characteristic "Unit of measure" on
the "Processing Rules" screen in automatic planning.

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?

Add the characteristic "Unit of measure" to your planning layout.
In automatic planning, choose "Retain" for the characteristic "Unit of
measure.

• What is the cause and solution for SAP error message KG076 - Quantities with different units cannot be added together ?

  The SAP error message KG076, which states "Quantities with different units cannot be added together," typically occurs in the context of inventory management, production planning, or any module where quantities are being processed. This error indicates that there is an attempt to perform an operation (like addition) on quantities that are expressed in different units of measure (UoM), which is not allowed.
  Cause:
  
  Different Units of Measure: The most common cause is that the quantities being processed are in different units (e.g., kilograms vs. grams, liters vs. milliliters).
  Configuration Issues: There may be a configuration issue in the material master data where the base unit of measure is not set correctly.
  Data Entry Errors: Manual data entry errors can lead to inconsistencies in the units of measure.
  Conversion Factors: If the conversion factors between different units are not defined or are incorrect, this can lead to the error.
  
  Solution:
  
  Check Units of Measure: Verify the units of measure for the quantities involved in the operation. Ensure that they are the same or can be converted to a common unit.
  Convert Units: If the quantities are in different units, convert them to a common unit before performing the operation. This can often be done using conversion factors defined in the material master.
  Review Material Master Data: Check the material master records for the items involved to ensure that the base unit of measure and alternative units of measure are correctly defined.
  Adjust Configuration: If necessary, adjust the configuration settings in SAP to ensure that the units of measure are set up correctly for the materials being processed.
  Data Validation: Implement validation checks in data entry processes to prevent the entry of quantities in different units.
  
  Related Information:
  
  Material Master: The material master in SAP contains information about the materials used in the organization, including their units of measure.
  Unit of Measure Conversion: SAP allows for the definition of conversion factors between different units of measure, which can be set up in the material master.
  Transaction Codes: You can use transaction codes like MM03 (Display Material), MM02 (Change Material), or MM01 (Create Material) to check and modify material master data.
  Documentation: Refer to SAP documentation or help files for more detailed information on units of measure and how to manage them within the system.
  
  By following these steps, you should be able to resolve the KG076 error and ensure that quantities are correctly processed in SAP.
