3819262 - [SAP ICS] Posting Failed Error: 140(CTE_FIN_POSTING): Posting failed due to missing content. Please check CLEARING_ACCOUNT_CODE with ID XXXXX

It's important to understand that a posting failure could occur not only due to SAP Concur configuration, but also due to the SAP configuration, therefore troubleshooting is required to understand where the issue may be. 

Before creating a support ticket with SAP Concur:
Reach out to your system administrators and check your system configurations on both the SAP and SAP Concur side.

Verify data coming in JSON to your SAP FI System: How can I verify the data sent from Concur to SAP ICS (JSON file)?

A certain financial document has failed posting in SAP with error: 140(CTE_FIN_POSTING): Posting failed due to missing content. Please check CLEARING_ACCOUNT_CODE with ID &1

The posting failure is caused by a missing Cash Advance Account Code in the user’s profile, which is required as the clearing account code. The issue can be resolved by reviewing the expense report and cash advance JSON files. Ensure that a Cash Advance Account Code is properly configured in the user’s Concur profile; if it is missing, it must be completed. After correcting the configuration, the document should be recalled, and the employee must refresh the document data before retrying the posting. If the posting still fails, a Concur Support Case must be opened for further assistance. , KBA , CON-EXP-CAV , Cash Advance , CON-TRV-ADM-USR-PRO , Profile , Problem
