How To Fix W8074 - Element & cannot be read with structure &

SAP Error Message - Details

• Message type: E = Error

• Message class: W8 - Workflow: Expressions, data flow

• Message number: 074

• Message text: Element & cannot be read with structure &

What causes this issue?

Element &v1& is in the container as a character string.
Structure &v2& is for reading element &V1& (via binding definition or
setting parameters of expression evaluation). But, structure &v2& is
not purely character string-based (does not contain only fields of the
internal types CNDT). Therefore, element &v1& cannot be read with
structure &v2&.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message W8074 - Element & cannot be read with structure & ?

  SAP Error Message:
  
  W8074 Element & cannot be read with structure &
  
  Cause:
  This warning message occurs when there is an attempt to read or access a component (field or element) of a structure using an incompatible or incorrect structure type. Essentially, the program tries to read an element of a structure but the structure definition used does not contain that element or the structure types do not match.
  Typical scenarios include:
  
  Using a MOVE or READ TABLE statement where the target structure does not have the specified element.
  Accessing a field of a structure variable that is declared with a different type than expected.
  Mismatch between the data object and the structure definition used in the code.
  
  
  Explanation:
  
  Element & refers to the field or component name that the program tried to access.
  Structure & refers to the structure type or variable name that was used to read the element.
  
  The warning indicates that the element is not part of the structure, so the read operation cannot be performed correctly.
  
  Solution:
  
  
  Check the structure definitions:
  
  Verify that the structure you are using actually contains the element you are trying to read.
  Use transaction SE11 to check the structure definition.
  
  
  
  Check the data declarations:
  
  Ensure that the variable or work area you are using is declared with the correct structure type.
  If you are using a generic or different structure, adjust the declaration or the code accordingly.
  
  
  
  Adjust the code:
  
  If you are reading data from a table or structure, make sure the field names and structure types match.
  Use field symbols or data references carefully to avoid type mismatches.
  
  
  
  Use proper type casting or conversion:
  
  If you need to read data from a generic structure, consider using field symbols or ASSIGN COMPONENT statements with proper checks.
  
  
  
  
  Example:
  TYPES: BEGIN OF ty_struct1,
           field1 TYPE i,
           field2 TYPE c LENGTH 10,
         END OF ty_struct1.
  
  TYPES: BEGIN OF ty_struct2,
           field3 TYPE i,
           field4 TYPE c LENGTH 10,
         END OF ty_struct2.
  
  DATA: ls_struct1 TYPE ty_struct1,
        ls_struct2 TYPE ty_struct2.
  
  " Incorrect access - trying to read field1 from ls_struct2 which does not have it
  WRITE ls_struct2-field1. " This will cause W8074 warning
  Correction:
  Make sure to access only fields that exist in the structure:
  WRITE ls_struct1-field1. " Correct
  
  Related Information:
  
  This is a warning (W) message, not an error, so the program will continue but the data read may be incorrect or incomplete.
  Check the ABAP documentation for READ TABLE, MOVE, and structure handling.
  Use debugging to inspect the runtime types of variables and structures.
  If using dynamic or generic programming techniques, ensure proper type checks before accessing components.
  
  
  Summary:
  
  The warning W8074 Element & cannot be read with structure & indicates a mismatch between the element being accessed and the structure type used. Verify structure definitions, data declarations, and adjust the code to ensure the element exists in the structure before accessing it.
