3634253 - Error: "Cannot post document. Concur test entity is connected" (CTE_FND_POSTING134) - (CTE)

When trying to post a Concur document to SAP S/4HANA Cloud Public Edition 2508, you get the error:

• Cannot post document. Concur test entity is connected.
  Message no. CTE_FND_POSTING134

SAP S/4HANA Cloud Public Edition 2608

1. Access Concur Posting Documents Monitor.
2. Import and post a document.

With SAP S/4HANA Cloud Public Edition 2508, a new check was implemented.

The logic was enhanced at 2608, therefore the correct approach is when connecting an SAP productive system, ensure that you are also connecting to a Concur productive system.

If for any reason you need to revert to previous logic, an option is to deactivate the check ID CHECK_CONCUR_AND_SAP_SYSTEM_TYPE for the document type of choice. This can be done via app "Concur Integration Setup", click at "Menu" and select "Finance" -> "Configuration" -> "Activate Posting Check". Note that the correct procedure is to use a Concur production system along to an SAP production system to avoid any possible issue, proceed by your own risk.
