SAP Error Message - Details

• Message type: E = Error

• Message class: AFX_WIZARDS - Messages from AFX Wizards

• Message number: 105

• Message text: The total length of the structure must not exceed 40 bytes

What causes this issue?

The external parallel processing key has been restricted to 40 Bytes.
Therefore, the total length of the structure definition must not exceed
40 Bytes.

System Response

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

How to fix this error?

Define a structure with a maximum length of 40 Bytes.

• What is the cause and solution for SAP error message AFX_WIZARDS105 - The total length of the structure must not exceed 40 bytes ?

  The SAP error message AFX_WIZARDS105, which states "The total length of the structure must not exceed 40 bytes," typically occurs when you are working with structures in ABAP (Advanced Business Application Programming) or when defining data structures in SAP that exceed the maximum allowed length.
  Cause:
  The error is caused by defining a structure (like a custom table or a data structure) that has a total length greater than 40 bytes. This can happen when:
  
  You are trying to create a structure with too many fields or fields that are too large.
  The combined length of all fields in the structure exceeds the 40-byte limit.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Structure Definition:
  
  Check the fields defined in the structure. Ensure that the total length of all fields does not exceed 40 bytes.
  If you have fields that are too large, consider reducing their size or changing their data types.
  
  
  
  Optimize Field Usage:
  
  If possible, combine smaller fields into a single field or use more compact data types (e.g., using CHAR instead of STRING).
  Remove any unnecessary fields that do not contribute to the required functionality.
  
  
  
  Split the Structure:
  
  If the structure is inherently complex and requires more than 40 bytes, consider splitting it into multiple smaller structures. You can then use these smaller structures in your program logic as needed.
  
  
  
  Check for Implicit Fields:
  
  Sometimes, implicit fields (like timestamps or user IDs) may be added automatically. Ensure that these are accounted for in your total length calculation.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or the ABAP programming guidelines for best practices on defining structures and data types.
  
  
  
  Related Information:
  
  Data Types: Familiarize yourself with the different data types in ABAP and their respective lengths. For example, CHAR, NUMC, and DATS have specific lengths that can impact your structure.
  ABAP Dictionary: Use the ABAP Dictionary (transaction SE11) to define and manage your structures. It provides tools to check the total length and structure definitions.
  Performance Considerations: Keep in mind that overly complex structures can impact performance. Aim for simplicity and efficiency in your data definitions.
  
  By following these steps, you should be able to resolve the AFX_WIZARDS105 error and successfully define your data structures within the constraints of SAP.
