• What is the cause and solution for SAP error message SMT091 - Step &1 transformation &2: Double call-up sequence &3 ?

  The SAP error message SMT091 typically indicates an issue related to the transformation process in the SAP system, particularly when dealing with data transfer or data transformation in the context of SAP Data Services or SAP BW (Business Warehouse). The error message suggests that there is a double call-up sequence for a specific transformation step.
  Cause:
  The error can occur due to several reasons, including:
  
  Incorrect Configuration: The transformation might be incorrectly configured, leading to multiple calls to the same transformation step.
  Data Flow Issues: There may be issues in the data flow design, where the same transformation is being invoked multiple times unintentionally.
  Concurrency Issues: If multiple processes are trying to execute the same transformation simultaneously, it can lead to this error.
  Programming Errors: Custom code or scripts that are part of the transformation might be causing unintended double calls.
  
  Solution:
  To resolve the SMT091 error, you can take the following steps:
  
  Check Transformation Configuration: Review the configuration of the transformation step in question. Ensure that it is set up correctly and that there are no duplicate calls.
  Review Data Flow Design: Analyze the data flow to ensure that the transformation is not being called multiple times. Look for any loops or conditions that might cause repeated calls.
  Debugging: If you have access to debugging tools, use them to trace the execution of the transformation and identify where the double call is occurring.
  Concurrency Control: If the issue is related to concurrent execution, consider implementing locks or other concurrency control mechanisms to prevent simultaneous calls to the same transformation.
  Check Custom Code: If there is any custom code involved in the transformation, review it for logic errors that might lead to double execution.
