• What is the cause and solution for SAP error message WER231 - Field &1 has already been added ?

  SAP Error Message:
  
  WER231 - Field &1 has already been added
  
  Cause:
  This error occurs when you try to add a field to a structure, table, or internal table that already contains a field with the same name. In other words, the system detects a duplicate field name during the definition or modification of a data structure or table.
  Common scenarios include:
  
  Adding a field to a structure or table where the field name already exists.
  Modifying or enhancing a structure and accidentally duplicating a field.
  During runtime, appending fields dynamically or merging structures with overlapping field names.
  
  
  Solution:
  
  
  Check the field names:
  
  Review the structure or table definition to ensure that the field you are trying to add does not already exist.
  
  
  Rename the field:
  
  If you need to add a similar field, use a different field name to avoid duplication.
  
  
  Adjust your code or data dictionary objects:  
  
  If you are working in ABAP code, check the internal table or structure declarations.
  If you are working with Data Dictionary (SE11), verify the structure or table fields.
  
  
  
  Debug or trace:
  
  If the error occurs during runtime, use debugging to check where the field is being added twice.

  ABAP Programming: When working with internal tables or structures, ensure no duplicate field names.
  Enhancements/User Exits: Sometimes, enhancements add fields to structures; verify that these do not cause duplicates.
  
  
  Example:
  If you have a structure ZSTRUCT with fields FIELD1, FIELD2, and you try to add FIELD1 again, SAP will raise WER231.
