• What is the cause and solution for SAP error message SMT094 - An initial transformation is not allowed ?

  The SAP error message SMT094, which states "An initial transformation is not allowed," typically occurs in the context of SAP Data Services or SAP Process Integration (PI) when there is an issue with the configuration of a transformation step in a data flow or mapping process.
  Cause:
  The error usually arises due to one of the following reasons:
  
  
  Incorrect Transformation Configuration: The transformation step is not properly configured, or it is being used in a way that is not allowed. For example, an initial transformation might be expected to have a source but is not correctly linked to one.
  
  
  Data Flow Logic: The data flow logic may be incorrect, where a transformation is expected to have a preceding step that provides input data, but it does not.
  
  
  Mapping Issues: If you are working with mappings, the error can occur if the mapping is trying to perform an operation that requires an initial transformation but is not set up correctly.
  
  
  Solution:
  To resolve the SMT094 error, you can take the following steps:
  
  
  Check Transformation Configuration:
  
  Review the configuration of the transformation step that is causing the error. Ensure that it is correctly set up and that all required fields and parameters are filled in.
  
  
  
  Verify Data Flow:
  
  Ensure that the data flow leading to the transformation is correctly defined. There should be a valid source that feeds data into the transformation. If the transformation is meant to be the first step, ensure that it is designed to handle that role.
  
  
  
  Review Mapping Logic:
  
  If you are working with mappings, check the logic to ensure that the initial transformation is correctly defined and that it has the necessary input data.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific version you are using. There may be specific guidelines or restrictions related to the transformations that you need to follow.
  
  
  
  Testing:
  
  After making changes, test the data flow or mapping again to see if the error persists. 
  
  
  
  Seek Help from SAP Support:
