• What is the cause and solution for SAP error message AD615 - Cluster & (function fields cannot be changed) ?

  The SAP error message AD615, which states "Cluster & (function fields cannot be changed)," typically occurs when there is an attempt to modify fields in a cluster table that are not allowed to be changed. Cluster tables in SAP are special types of database tables that store data in a compressed format, and certain fields within these tables are defined as function fields, which are not meant to be altered.
  Cause:
  
  Modification Attempt: The error usually arises when a program or transaction tries to update or change a field in a cluster table that is defined as a function field.
  Data Integrity: SAP enforces this restriction to maintain data integrity and consistency within the cluster tables.
  
  Solution:
  
  Review the Code: Check the ABAP code or the transaction that is causing the error. Look for any attempts to modify fields in cluster tables, especially those defined as function fields.
  Avoid Modifications: Ensure that your program does not attempt to change these fields. If you need to update data, focus on the fields that are allowed to be modified.
  Use Correct Logic: If you need to perform operations that involve cluster tables, consider using appropriate function modules or methods that are designed to handle data in these tables without violating the constraints.
  Consult Documentation: Refer to SAP documentation or the Data Dictionary (SE11) to understand the structure of the cluster table and which fields are function fields.
