The invoice posting did not occur due to the combination of line items. It is strongly recommended to create two separate invoices for each line item to avoid conflicts.
To resolve the issue, follow the steps below:

1. Verify the withholding tax codes assigned to the line items in the Supplier Invoice.
2. Identify if the line items have conflicting withholding tax codes, such as one due at payment and another due at invoicing.
3. Create separate Supplier Invoices for each line item to avoid conflicts in withholding tax codes.
4. Ensure the withholding tax configuration is correctly maintained in the localization toolkit with the implementation partner.
5. Test the same scenario in a test system to confirm the resolution.
