• What is the cause and solution for SAP error message SPXN036 - Mapping must either contain synchronous or asynchronous methods ?

  The SAP error message SPXN036, which states "Mapping must either contain synchronous or asynchronous methods," typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when defining a mapping program. This error indicates that the mapping you are trying to implement has a mix of synchronous and asynchronous methods, which is not allowed.
  Cause:
  
  Mixed Method Types: The mapping you are trying to create includes both synchronous and asynchronous methods. In SAP PI/PO, a mapping can only be either synchronous (where the request and response are processed in a single call) or asynchronous (where the request is processed independently of the response).
  Incorrect Configuration: The configuration of the mapping might not align with the expected method type for the integration scenario you are working on.
  
  Solution:
  
  Review Mapping Logic: Check the mapping logic you have implemented. Ensure that all methods used in the mapping are either synchronous or asynchronous. You may need to refactor the mapping to ensure consistency.
  Adjust Integration Scenario: If your integration scenario requires both synchronous and asynchronous processing, consider splitting the logic into two separate mappings or processes, one for each method type.
  Check Receiver Determination: Ensure that the receiver determination and interface determination are correctly set up to match the expected method type.
  Use Appropriate Mapping Tools: If you are using graphical mapping or XSLT, ensure that the mapping tool you are using is appropriate for the type of processing you intend to perform.
  
  Related Information:
  
  Documentation: Refer to the SAP Help Portal for detailed documentation on mapping in SAP PI/PO, which provides guidelines on how to create and configure mappings correctly.
  SAP Community: Engage with the SAP Community forums where you can find discussions and solutions related to similar issues faced by other users.
  Testing: After making changes, thoroughly test the mapping to ensure that it behaves as expected and that the error does not reoccur.
  
  By ensuring that your mapping is consistent in terms of method type and correctly configured, you should be able to resolve the SPXN036 error.
