ERP to C4 business partner replication fails with the error "Federal Business Number is invalid" and inbound status "Error while processing inbound third-party communication" for interface BusinessPartnerReplication.

SAP Cloud for Customer

1. Trigger a Business Partner replication from the source ERP system to C4C.
2. Open Web Service Message Monitoring in C4C.
3. Filter inbound messages in the BusinessPartnerReplication interface.
4. Observe the error status "Error while processing inbound third party communication" and the error text "Federal Business Number is invalid".

• The tax identification value (federal business number) provided by the source system does not comply with the country/region-specific validation rules enforced in C4C (for example, the Luhn check for Canadian federal business numbers), so the inbound message is rejected.

Note: Refer to the link more details on Luhn check: https://en.wikipedia.org/wiki/Luhn_algorithm

The Luhn algorithm (developed by IBM scientist Hans Peter Luhn), also known as the “modulus 10” or “mod 10” algorithm, is a simple check-digit formula used to validate various identification numbers. Its purpose is to ensure that when a number is entered manually, the system can quickly detect errors using this validation logic.

1. Correct the tax number in the source system so that it matches the required country/region format and category; then reprocess the BusinessPartnerReplication message to C4C.
2. If the business decision is to accept the tax number as maintained in the source system and avoid the target-side validation, adjust the country settings in C4C:
   1. Go to the Business Configuration work center.
   2. Go to the Implementation Projects work center view.
   3. Open Fine-Tune and search for "Countries/Regions."
   4. Choose "Edit Countries/Regions" and select the relevant country/region.
   5. In the Tax Attributes tab, set "Tax field Check Enabled" to "No."
   6. Save and reprocess the BusinessPartnerReplication message.
3. Note that standard validation cannot be removed at the object level; optionally, propose an enhancement via the influence site if different behavior is required.
