3818911 - [SAP ICS] Posting Failed Error: 070(CTE_FIN_POSTING): Posting failed. Specify tax code for TaxReclaimCode XX

Important: A posting failure could occur not only due to Concur configuration but also due to the SAP configuration. Therefore, troubleshooting is necessary to identify the root cause of the issue.

Before creating a support ticket with SAP Concur:

• Please contact your system administrators and check your system configurations on both the SAP and Concur side. 
• The SAP system administrator provides details of the posting error, such as the document ID, document type, affected entry ID, TaxReclaimCode/NonDomesticCode, etc.
• It is important to verify the data transmitted in JSON format from Concur to the SAP FI System: How can I verify the data sent from Concur to SAP ICS (JSON file)?
