How To Fix KH618 - Function is only permitted with a uniform currency or unit of measure

SAP Error Message - Details

• Message type: E = Error

• Message class: KH - CO-PA Reporting

• Message number: 618

• Message text: Function is only permitted with a uniform currency or unit of measure

What causes this issue?

You tried to call up the function "&V1&". However, it only makes sense
to call up this function for columns that share the same currency or
unit of measure. In this case, the column you have selected does not
meet this criterion and hence the function is not permitted.
This column has a unit that is dependent on a characteristic. You can
tell this from one of the following:
The characteristic that the unit is dependent on is the current
drilldown characteristic.
In this case, the units are generally changed per row.
Alternatively, the characteristic that determines the unit is defined
in the list header.
In this case, the unit is generally changed when you scroll down to a
different characteristic value.

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

System Response

You cannot perform function "&V1&" for this column.

How to fix this error?

If the column is currency-related, you first need to translate the
currency of its units into a uniform currency before calling up the
function again.

• What is the cause and solution for SAP error message KH618 - Function is only permitted with a uniform currency or unit of measure ?

  The SAP error message KH618 ("Function is only permitted with a uniform currency or unit of measure") typically occurs in the context of cost planning or cost allocation processes within SAP. This error indicates that the system has detected a mismatch in the currencies or units of measure being used in a particular transaction or operation. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Currency Mismatch: The error often arises when you are trying to perform calculations or operations that involve multiple currencies, and the system requires all values to be in the same currency.
  Unit of Measure Mismatch: Similar to currency, if you are working with quantities that have different units of measure (e.g., kilograms vs. pounds), the system will not be able to process the request.
  Data Entry Errors: Incorrect data entry or configuration in master data (like cost centers, internal orders, etc.) can lead to this error.
  Inconsistent Master Data: If the master data for materials, cost centers, or other relevant entities is not consistent in terms of currency or unit of measure, it can trigger this error.
  
  Solutions:
  
  Check Currency Settings: Ensure that all relevant documents, master data, and transactions are using the same currency. If necessary, convert currencies to a common one before processing.
  Standardize Units of Measure: Make sure that all quantities involved in the transaction are expressed in the same unit of measure. If you need to convert units, do so before proceeding with the operation.
  Review Master Data: Check the master data for cost centers, internal orders, and other relevant entities to ensure that they are set up correctly and consistently.
  Use Currency Conversion: If you are dealing with multiple currencies, consider using SAP's currency conversion functions to convert all amounts to a single currency before processing.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling currency and unit of measure issues in your version of SAP.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes that may help in troubleshooting, such as CK11N (Create Cost Estimate), CK40N (Costing Run), or KSB1 (Cost Centers: Actual Line Items).
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  User Roles and Authorizations: Ensure that the user has the necessary authorizations to perform the operations, as sometimes restrictions can lead to unexpected errors.
  
  By addressing the underlying causes of the KH618 error, you should be able to resolve the issue and proceed with your cost planning or allocation tasks in SAP.
