You post supplier invoice documents. After the posting, when you check the journal entries, you found Work Item field is populated although the account assignment is cost center. You expect the field should not be populated under this situation, since it impacted the functional area derivation when using substitution.
SAP S/4HANA Cloud
Reproducing the Issue
Post supplier invoice document and check the created journal entry.
The work item is designed to structure the G/L account, not the project. It can also be used in combination with other account assignment objects, like cost center.
Accordingly, the posting logic for document type ER Manual Expense Travel was designed to provide the work item also on the item posted to the cost center of the employee.
This is how the functionality has always worked, and even if we would want to change that, a change would impact existing customers.
To derive the correct functional area, please enhance your substitution by using more attributes in the preconditions.
