Error message
Failed to export into SAP S/4 HANA. Either the WBS element or the internal order needs to be empty or statistical.Affected ERP integrations
SAP S/4HANA®
Cause
When exporting an expense, you may encounter an error indicating that multiple true account assignments have been entered.
In SAP S/4HANA, your setup may allow you to enter more than one cost assignment object on an expense, for example, combining a Cost Center with a Project to track both department and project budgets. However, SAP S/4HANA may require that only one of these objects acts as the true (real) financial destination absorbing the actual cost. Any additional objects must be statistical - meaning they are used purely for reporting and background tracking.
This error happens because SAP S/4HANA received both a WBS element and an Internal Order marked as true destinations for the exact same expense line. Since SAP S/4HANA cannot split the actual financial ownership between these two specific objects, the transaction is rejected.
Solution
Before changing anything in SAP S/4HANA, look at how the expense is coded in Payhawk:
Log in to the Payhawk Web Portal.
Navigate to the Expenses app.
Open the affected expense by clicking on it and review the tracking fields.
Check if both an Internal Order and a Project/WBS Element have been selected together.
If your specific company setup does not require tracking both for this expense type, simply clear out the unnecessary field so that only one remains.
If your organization workflow does require you to enter both fields together to capture reporting data, you must configure one of them, usually the Internal Order, as a statistical object in SAP S/4HANA so they can coexist without a conflict.
SAP S/4HANA Public Cloud Edition
To resolve the issue in SAP S/4HANA Public Cloud Edition:
Log into your SAP Fiori launchpad and open the Manage Internal Orders app.
Search for the Internal Order ID being used for this expense.
In the order details, look for the Control Data or general settings section.
Ensure that the Statistical Order checkbox is turned ON. This tells SAP S/4HANA that the WBS element will absorb the actual financial cost, while this order is just for tracking.
Save your changes.
SAP S/4HANA Private Cloud Edition
To resolve the issue in SAP S/4HANA Private Cloud Edition:
Go to transaction code
KO02(Change Internal Order).Enter the Internal Order number and press Enter.
Go to the Control data tab.
Locate the Statistical order checkbox and select it.
Click Save to update the order master data.
Next steps
Once you have either adjusted the fields in Payhawk or updated the master data configuration in SAP S/4HANA to allow multiple objects, go back to Payhawk and follow the steps:
Log in to the Payhawk Web Portal.
Go to the Expenses app.
Locate the pending expense and click Review to re-try the export.
