• What is the cause and solution for SAP error message SMT150 - Parameter &1 is not defined in Customizing of the mapping step ?

  The SAP error message SMT150, which states "Parameter &1 is not defined in Customizing of the mapping step," typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when there is an issue with the configuration of a mapping step in a mapping program.
  Cause:
  The error indicates that a required parameter (denoted by &1) for a specific mapping step has not been defined in the Customizing settings. This can happen due to several reasons:
  
  Missing Configuration: The parameter might not have been set up in the mapping configuration.
  Incorrect Mapping: The mapping might be referencing a parameter that does not exist or has been deleted.
  Transport Issues: If the mapping was transported from one system to another, the necessary parameters might not have been included in the transport request.
  Version Mismatch: There could be a version mismatch between the mapping program and the parameters defined in Customizing.
  
  Solution:
  To resolve the SMT150 error, you can follow these steps:
  
  
  Check Mapping Configuration:
  
  Go to the relevant mapping configuration in the Integration Directory or the relevant transaction (like SXMB_IFR for Integration Flow).
  Verify that all required parameters are defined correctly.
  
  
  
  Define Missing Parameters:
  
  If you identify that a parameter is indeed missing, you will need to define it in the Customizing settings for the mapping step.
  Navigate to the appropriate Customizing transaction (like SPRO) and ensure that the parameter is set up correctly.
  
  
  
  Review Transport Requests:
  
  If the mapping was transported, check the transport request to ensure that all necessary objects and parameters were included.
  If not, you may need to manually configure the missing parameters in the target system.
  
  
  
  Check for Documentation:
  
  Review any documentation related to the mapping step to ensure that you are aware of all required parameters and their expected values.
  
  
  
  Testing:
  
  After making the necessary changes, test the mapping again to ensure that the error is resolved.
