SPXN188 - Details

• The SAP error message SPXN188, which states "A mapping mode has to be assigned," typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when there is an issue with the mapping configuration in your integration scenario. This error indicates that the system expects a mapping mode to be defined for the message mapping but it has not been assigned.
  
  Cause:
  
  Missing Mapping Mode: The most common cause of this error is that the mapping mode (e.g., "Standard," "Enhanced," or "Custom") has not been assigned to the mapping configuration.
  Incorrect Configuration: There may be an issue with the configuration of the integration flow or the mapping itself, leading to the system not recognizing the mapping mode.
  Transport Issues: If the mapping was transported from one system to another, it might not have been properly configured in the target system.
  
  
  Solution:
  
  
  Assign Mapping Mode:
  
  Go to the Integration Directory in your SAP PI/PO
