  The SAP error message FDT_EXPRESSIONS587 indicates that there is an issue with the structure of a table in the context of Field-Based Data Transformation (FDT) or similar data processing scenarios. The error message suggests that there is a conflict between the name of a table and its structure, which can lead to confusion in data processing.
  Cause:

  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Naming Conventions: Ensure that the names of tables and structures are unique. If a table and a structure share the same name, consider renaming one of them to avoid conflicts.
  
  
  Review Data Transformation Settings: Go through the configuration settings in the FDT or the relevant data processing tool to ensure that the mappings are correctly defined and that there are no ambiguities in the references to tables and structures.
  
  
  Adjust Data Model: If the issue is related to the data model, review the definitions of the tables and structures in the ABAP Dictionary (transaction SE11) to ensure they are correctly defined and do not conflict with each other.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to FDT and data transformation for any specific guidelines or best practices that may help in resolving the issue.
  
  
  Testing: After making changes, test the data transformation or processing again to ensure that the error has been resolved.
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), or FDT-related transactions to investigate and resolve the issue.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
