• What is the cause and solution for SAP error message SPXN038 - Synchronous mapping must have exactly one target method ?

  The SAP error message SPXN038 indicates that there is an issue with a synchronous mapping in your SAP PI/PO (Process Integration/Process Orchestration) configuration. Specifically, it states that the synchronous mapping must have exactly one target method defined. This error typically arises when the mapping configuration does not meet the requirements for synchronous processing.
  Cause:
  
  Multiple Target Methods: The mapping configuration may have been set up with more than one target method, which is not allowed for synchronous mappings.
  No Target Method Defined: Conversely, if no target method is defined, the system will also throw this error.
  Incorrect Mapping Configuration: There may be a misconfiguration in the mapping settings that leads to ambiguity in determining the target method.
  
  Solution:
  To resolve the SPXN038 error, follow these steps:
  
  
  Check Mapping Configuration:
  
  Open the mapping configuration in the SAP PI/PO Integration Builder.
  Ensure that there is exactly one target method defined for the synchronous mapping.
  
  
  
  Define Target Method:
  
  If there is no target method defined, you need to specify one. This is typically done in the mapping configuration where you define the target service or operation.
  
  
  
  Remove Extra Target Methods:
  
  If there are multiple target methods defined, you need to remove the extra ones so that only one remains.
  
  
  
  Validate Mapping:
  
  After making the necessary changes, validate the mapping to ensure that it is correctly configured and does not produce any errors.
  
  
  
  Test the Mapping:
  
  Once the configuration is corrected, perform a test to ensure that the synchronous mapping works as expected without throwing the SPXN038 error.
  
  
  
  Related Information:
  
  Synchronous vs. Asynchronous Mappings: Understand the difference between synchronous and asynchronous mappings in SAP PI/PO. Synchronous mappings require a single response to be returned immediately, while asynchronous mappings can handle multiple responses or messages.
  Integration Builder: Familiarize yourself with the Integration Builder in SAP PI/PO, as this is where you configure mappings, interfaces, and other integration components.
  Documentation: Refer to SAP documentation or community forums for additional insights and examples related to mapping configurations and error handling.
  
  By following these steps, you should be able to resolve the SPXN038 error and ensure that your synchronous mapping is correctly configured.
