How To Fix KE0C137 - &3 can only be summarized together with &1 -> Save not possible

SAP Error Message - Details

• Message type: E = Error

• Message class: KE0C - CO-PA: Customizing checks

• Message number: 137

• Message text: &3 can only be summarized together with &1 -> Save not possible

What causes this issue?

Characteristic "&V3&" ("&V4&") is dependent on characteristic "&V1&" ("
&V2&"). It does not make sense just to exclude the higher-level
characteristic "&V1&" alone from the segment-level characteristics
because the characteristic values of the dependent characteristics are
only unique when together with the higher-level characteristic.

System Response

Your settings could not be saved because they would cause the data to
be inconsistent.

How to fix this error?

Exclude the dependent characteristic "&V3&" as well from the
segment-level characteristics.

• What is the cause and solution for SAP error message KE0C137 - &3 can only be summarized together with &1 -> Save not possible ?

  The SAP error message KE0C137 indicates that a certain condition has not been met for saving a particular document or entry in the Controlling (CO) module. Specifically, the message states that the object (e.g., a cost center, internal order, or project) identified by &3 can only be summarized together with another object identified by &1, which means that the system is enforcing a rule regarding how these objects can be processed together.
  Cause:
  
  Summarization Rules: The error typically arises when there are summarization rules in place that dictate how certain cost objects can be grouped or summarized. If the system detects that the objects are not compatible for summarization, it will prevent the save operation.
  Data Inconsistency: There may be inconsistencies in the data that prevent the system from processing the entries as intended.
  Configuration Issues: The configuration settings in the Controlling module may not be set up correctly, leading to this restriction.
  
  Solution:
  
  Check Configuration: Review the configuration settings in the Controlling module to ensure that the summarization rules are set up correctly. This may involve checking the settings for cost centers, internal orders, or other relevant objects.
  Review Object Relationships: Investigate the relationships between the objects involved (&1 and &3). Ensure that they are compatible for summarization as per the business rules defined in your organization.
  Data Validation: Validate the data being entered to ensure that it meets the necessary criteria for summarization. This may involve checking for missing or incorrect entries.
  Consult Documentation: Refer to SAP documentation or help resources for specific details on the summarization rules applicable to your scenario.
  Contact Support: If the issue persists, consider reaching out to your SAP support team or consulting with an SAP expert who can provide more tailored assistance based on your system configuration and business processes.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in the CO module, such as KSB1 (Cost Centers: Actual Line Items) or KOB1 (Orders: Actual Line Items), to analyze the data related to the error.
  SAP Notes: Check for any SAP Notes related to this error message, as they may provide additional insights or patches that could resolve the issue.
  User Exits and BAdIs: If custom logic is implemented in your SAP system, review any user exits or Business Add-Ins (BAdIs) that might affect the summarization process.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
