• What is the cause and solution for SAP error message AD323 - & (key fields are not at the beginning of the table) ?

  The SAP error message AD323 indicates that there is an issue with the key fields in a database table. Specifically, the error message states that "key fields are not at the beginning of the table." This typically occurs when the key fields of a table are not defined in the correct order or position, which can lead to issues with data retrieval and integrity.
  Cause:
  
  Incorrect Table Definition: The key fields in the table are not defined at the beginning of the table structure. In SAP, key fields should always be positioned at the start of the table definition.
  Data Dictionary Issues: If the table was modified or created incorrectly in the Data Dictionary (SE11), it may lead to this error.
  Transport Issues: If the table definition was transported from one system to another, it might not have been correctly defined in the target system.
  
  Solution:
  
  
  Check Table Definition:
  
  Go to transaction SE11 (Data Dictionary).
  Enter the name of the table that is causing the error and click on "Display."
  Check the order of the fields in the table definition. Ensure that all key fields are positioned at the beginning of the table.
  
  
  
  Modify Table Structure:
  
  If the key fields are not at the beginning, you will need to modify the table structure.
  Click on "Change" and rearrange the fields so that all key fields are at the top of the table definition.
  Save and activate the changes.
  
  
  
  Transport Changes:
  
  If the issue arose due to a transport, ensure that the transport request is correctly configured and that the table definition is consistent across systems.
  
  
  
  Check for Dependencies:
  
  If the table is used in other programs or has dependencies, ensure that those are also updated accordingly after making changes to the table structure.
  
  
  
  Testing:
  
  After making the necessary changes, test the functionality that was causing the error to ensure that it has been resolved.
