• What is the cause and solution for SAP error message UAS200 - Step type &1 only allows one target field ?

  The SAP error message UAS200 indicates that a specific step type in a process (usually in a workflow or a data processing task) is configured to allow only one target field, but the configuration is attempting to assign multiple target fields. This typically occurs in the context of data transfer or transformation processes, such as in the SAP Data Services or SAP BW (Business Warehouse).
  Cause:
  The error is caused by the following scenarios:
  
  Incorrect Configuration: The step type you are using is designed to map data to a single target field, but the configuration mistakenly includes multiple target fields.
  Data Mapping Issues: When defining the mapping for a transformation or data flow, multiple fields may have been selected when only one is permitted.
  Step Type Limitations: Certain step types inherently support only a single target field due to their design and intended use.
  
  Solution:
  To resolve the UAS200 error, you can take the following steps:
  
  
  Review the Step Configuration:
  
  Go to the specific step in your workflow or data processing task that is generating the error.
  Check the target field settings and ensure that only one target field is specified.
  
  
  
  Modify the Mapping:
  
  If you have mistakenly mapped multiple fields, adjust the mapping to ensure that only one target field is selected for that step type.
  If you need to map multiple fields, consider using a different step type that supports multiple target fields.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific step type you are using to understand its limitations and correct usage.
  
  
  
  Testing:
  
  After making the necessary adjustments, test the workflow or data processing task again to ensure that the error is resolved.
