  The SAP error message TFW_API027 indicates that there is an issue with a function module where more than one entry exists for a specific combination of parameters. This typically occurs in scenarios where the system expects a unique entry but finds multiple records that match the criteria provided.
  Cause:
  The error is usually caused by one of the following:
  
  Data Duplication: There are multiple entries in the database table that match the criteria specified in the function module call. This can happen due to data inconsistencies or incorrect data entry.
  Incorrect Parameters: The parameters passed to the function module may not be specific enough to identify a unique record.
  Configuration Issues: In some cases, the configuration of the system may lead to multiple valid entries for the same criteria.
  
  Solution:
  To resolve the TFW_API027 error, you can take the following steps:
  
  
  Check the Data: 
  
  Use transaction codes like SE16 or SE11 to check the relevant database table for duplicate entries. Look for the specific combination of values that are causing the error.
  Identify the records that are causing the duplication and determine if they are valid or if they need to be corrected or deleted.
  
  
  
  Modify the Function Call:
  
  Review the parameters being passed to the function module. Ensure that they are specific enough to retrieve a unique record.
  If necessary, modify the logic in your code to handle cases where multiple records are returned, such as by adding additional filters.
  
  
  
  Consult Documentation:
  
  Review the documentation for the function module to understand its expected behavior and the parameters it requires. This can provide insights into how to structure your call correctly.
  
  
  
  Data Cleanup:
  
  If duplicates are found and are not valid, consider cleaning up the data to ensure that only unique entries exist for the criteria in question.
