• What is the cause and solution for SAP error message KH012 - You selected the function "&". The characteristic cannot be summarized. ?

  The SAP error message KH012 indicates that a characteristic cannot be summarized in the context of the function you are trying to execute. This typically occurs in the context of reporting or analysis in SAP, particularly when dealing with characteristics in a data model or when trying to aggregate data in a report.
  Cause:
  The error can arise due to several reasons:
  
  Incompatible Characteristics: The characteristic you are trying to summarize may not be compatible with the aggregation function you are using. For example, certain characteristics may not support summarization due to their data type or the way they are defined in the system.
  Missing Aggregation Settings: The characteristic may not have been set up to allow for summarization in the configuration settings of the InfoObject or the data model.
  Data Model Constraints: The data model may have constraints that prevent certain characteristics from being summarized together.
  Incorrect Function Usage: The function you are trying to use may not be appropriate for the selected characteristic.
  
  Solution:
  To resolve the KH012 error, you can take the following steps:
  
  
  Check Characteristic Settings:
  
  Go to the InfoObject maintenance in SAP and check the settings for the characteristic in question. Ensure that it is set up to allow summarization.
