This article answers some of the most frequently asked questions (FAQs) about the Payhawk-SAP S/4HANA® integration.
Can I connect one Payhawk account to multiple SAP S/4HANA systems?
No. Each Payhawk account connects to one SAP S/4HANA system at a time.
I added new GL accounts in SAP S/4HANA. Why do I not see them?
Trigger a manual category sync in Payhawk. The new accounts will appear right away.
What happens to blocked accounts?
Accounts that are blocked for posting in SAP S/4HANA are automatically excluded. If an account gets blocked after it is already in Payhawk, it will be removed on the next sync.
Can I choose different export types per category?
No, the export type is configured per expense type, such as card, bank or bill, cash, and reimbursement, not per category.
Can I fix bookkeeping mistakes?
Yes. Payhawk Administrators or Accountants can return an expense for review, make the needed adjustments, and send the updated expense back to SAP S/4HANA.
However, if you have enabled Automatic clearing during the integration setup, once both the expense and payment are exported to SAP S/4HANA, they will be automatically cleared against each other and locked. In this case, they cannot be edited in either Payhawk or SAP S/4HANA. If you attempt to return the expense for review, you’ll see a message explaining that any edits made in Payhawk will not sync back to SAP S/4HANA. Without Automatic clearing enabled, both entries remain editable after export.
Can Payhawk modify locked periods in SAP S/4HANA?
No, Payhawk will not modify any information in SAP S/4HANA from a locked period. When exporting expenses from Payhawk to SAP S/4HANA, the service period and the document date are important factors in determining the posting date in SAP S/4HANA.
In Payhawk, you can set a document date and a service period for each expense. The document date is the date of the invoice or receipt, while the service period is the period during which the service was provided. By default, if the document date and the service period are in different months, an error will occur during export to SAP S/4HANA, and the export will fail.
