How To Fix PAK_WB_FOUNDATION124 - The SUB_KEY part of the object key is longer than 120 characters

SAP Error Message - Details

• Message type: E = Error

• Message class: PAK_WB_FOUNDATION - Error messages for package SPAK_WB_FOUNDATION

• Message number: 124

• Message text: The SUB_KEY part of the object key is longer than 120 characters

What causes this issue?

You specified an object key whose SUB_KEY part is longer than the
supported 120 characters.
An object key is used to identify an package-assigned object in the
system. The object key consists of a type identifier(which tells the
system the type of the object), the key of the object's corresponding
main transport object, and the SUB_KEY part, which allows to
distinguishdifferent objects that are contained in the same main
transport object.
Due to technical restrictions, only the first 120 characters of the
SUB_KEY part can be stored on the database. Inorder to avoid "silent
truncation" of the additional characters, this error message was raised
and the operation youstarted was cancelled.

System Response

• What is the cause and solution for SAP error message PAK_WB_FOUNDATION124 - The SUB_KEY part of the object key is longer than 120 characters ?

  The SAP error message PAK_WB_FOUNDATION124 indicates that the SUB_KEY part of an object key exceeds the maximum allowed length of 120 characters. This error typically arises in the context of SAP applications that utilize object keys for various data management tasks, such as in the SAP Business Workflow or other components that rely on object keys for identification.
  Cause:
  The error is caused by the following:
  
  The SUB_KEY is a component of an object key that is used to uniquely identify an object within the SAP system.
  If the length of the SUB_KEY exceeds 120 characters, the system will throw this error to prevent data integrity issues or inconsistencies.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Source: Determine where the object key is being generated or used. This could be in a custom program, a workflow, or a standard SAP transaction.
  
  
  Check the Data: Review the data being passed as the SUB_KEY. Look for any fields or concatenated strings that may be contributing to the length exceeding 120 characters.
  
  
  Modify the Key: If possible, modify the logic that generates the SUB_KEY to ensure it does not exceed the character limit. This may involve:
  
  Truncating the SUB_KEY to fit within the limit.
  Using a different method to generate a unique identifier that adheres to the length restrictions.
  
  
  
  Review Custom Code: If the error is occurring in custom ABAP code, review the relevant code sections to ensure that the SUB_KEY is being constructed correctly and does not exceed the length limit.
  
  
  Testing: After making changes, thoroughly test the affected functionality to ensure that the error is resolved and that the system behaves as expected.
  
  
  Consult Documentation: If you are unsure about how to modify the key or if the error persists, consult SAP documentation or reach out to SAP support for further assistance.
  
  
  Related Information:
