• What is the cause and solution for SAP error message FDT_EXPRESSIONS513 - Operator &1 is not allowed for structures ?

  The SAP error message FDT_EXPRESSIONS513 indicates that an operator is being used in a context where it is not allowed for structures. This typically occurs in the context of Field-Based Data Transformation (FDT) or when working with expressions in ABAP where structures are involved.
  Cause:
  The error arises when you attempt to use an operator (like arithmetic or logical operators) on a structure rather than on its individual components (fields). Structures in ABAP are composite data types that can contain multiple fields, and operations need to be performed on these fields rather than on the structure as a whole.
  Solution:
  To resolve this error, you should:
  
  
  Identify the Structure: Determine which structure is causing the error. Look at the expression or operation that triggered the error.
  
  
  Access Individual Fields: Instead of applying the operator directly to the structure, access the individual fields of the structure. For example, if you have a structure my_struct with fields field1 and field2, and you want to add them, you should do:
  result = my_struct-field1 + my_struct-field2.
  
  
  Review the Logic: Ensure that the logic you are trying to implement makes sense in the context of the data types you are working with. If you are trying to perform operations that are not valid for the data types, you may need to rethink your approach.
  
  
  Check Documentation: If you are unsure about the operators that can be used with specific data types, refer to the SAP documentation or the ABAP programming guidelines.
  
  
  Related Information:
  
  Data Types in ABAP: Understanding the different data types in ABAP (like elementary types, structures, tables, etc.) is crucial for avoiding such errors.
  Field-Based Data Transformation (FDT): Familiarize yourself with how FDT works, especially if you are working with data transformations in SAP.
  Debugging: Use the debugger to step through your code and see where the error occurs. This can help you identify the specific operation that is causing the issue.
  
  By following these steps, you should be able to resolve the FDT_EXPRESSIONS513 error and ensure that your operations are correctly applied to the appropriate data types.
