  The SAP error message SPXN159, which states "Specify Source Consumer and Method before adding a Target Consumer," typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when configuring integration scenarios. This error indicates that the system requires you to define a source consumer and the associated method before you can add a target consumer in your integration flow.
  Cause:
  
  Incomplete Configuration: The error arises when the configuration for the source consumer is not fully defined. The system expects you to specify which source consumer (the system that sends the data) and the method (the operation that will be invoked) before you can proceed to define the target consumer (the system that receives the data).
  Missing Parameters: If the necessary parameters for the source consumer are not provided, the system cannot establish a proper mapping or connection to the target consumer.
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Define Source Consumer:

  Check Configuration:
  
  Review the configuration settings for the source consumer to ensure that all required fields are filled out correctly.
  Make sure that the source consumer is properly linked to the appropriate service interface.
  
  
  
  Add Target Consumer:
  
  Once the source consumer and method are defined, you can proceed to add the target consumer.
  Ensure that the target consumer is also configured correctly to receive the data from the source consumer.
  
  
  
  Testing:
  
  After making the necessary changes, test the integration scenario to ensure that the error is resolved and that data flows correctly between the source and target consumers.
