• What is the cause and solution for SAP error message FIN_RE_ABAP_ENG009 - Value of field symbol on field &2 of &1 changed. ?

  The SAP error message FIN_RE_ABAP_ENG009 indicates that the value of a field symbol has changed unexpectedly during the execution of an ABAP program. This typically occurs in the context of financial applications, particularly when dealing with data structures or internal tables.
  Cause:
  
  
  Field Symbol Changes: The error usually arises when a field symbol (a reference to a data object) is modified in a way that is not expected. This can happen if:
  
  The field symbol is pointing to a data object that has been changed or deleted.
  There are multiple references to the same data object, and one of them modifies the data.
  The program logic inadvertently alters the value of the field symbol.
  
  
  
  Concurrency Issues: If multiple processes are trying to access and modify the same data simultaneously, it can lead to unexpected changes.
  
  
  Incorrect Logic: There may be logical errors in the ABAP code that lead to unintended modifications of the field symbol.
  
  
  Solution:
  
  
  Review the Code: Check the ABAP code where the field symbol is defined and used. Ensure that:
  
  The field symbol is correctly assigned to the intended data object.
  There are no unintended modifications to the data object that the field symbol points to.
  
  
  
  Use of ASSIGN Statement: Ensure that the ASSIGN statement used to assign the field symbol is correctly implemented. If the data object is changed after the assignment, consider reassigning the field symbol.
  
  
  Debugging: Use the ABAP debugger to step through the code and monitor the value of the field symbol and the data object it points to. This can help identify where the change occurs.
  
  
  Locking Mechanisms: If concurrency is an issue, consider implementing locking mechanisms (e.g., using ENQUEUE and DEQUEUE) to prevent simultaneous modifications.
  
  
  Error Handling: Implement error handling to catch unexpected changes and provide meaningful messages or fallback logic.
  
  
  Related Information:
  
  Field Symbols: In ABAP, field symbols are used to create dynamic references to data objects. They are defined using the FIELD-SYMBOLS statement.
  Data Consistency: Maintaining data consistency is crucial in financial applications. Ensure that all data manipulations are atomic and well-structured.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. Sometimes, specific versions of SAP may have bugs that are documented in SAP Notes.
  
  If the issue persists after following these steps, consider reaching out to SAP support or consulting with an experienced ABAP developer for further assistance.
