• What is the cause and solution for SAP error message 1E644 - Only select lines with a user other than &1. ?

  The SAP error message 1E644 ("Only select lines with a user other than &1.") typically occurs in scenarios where a user is trying to perform an action (like processing or approving) on a document or transaction that is already assigned to the same user. This is a safeguard to prevent users from inadvertently processing their own entries, which could lead to conflicts of interest or errors.
  Cause:
  The error is triggered when:
  
  A user attempts to select or process a line item that is already assigned to them.
  The system is configured to restrict users from processing their own entries to maintain data integrity and accountability.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check User Assignment: Verify if the line items you are trying to select are indeed assigned to you. If they are, you will need to either:
  
  Change the user assignment of those line items to another user.
  Have another user process the line items.
  
  
  
  Change User: If you have the necessary permissions, you can change the user assignment for the line items in question. This may involve:
  
  Editing the document or transaction to assign it to a different user.
  Using transaction codes like SU01 to manage user assignments if applicable.
  
  
  
  Consult with a Supervisor: If you are unsure about changing user assignments or if you do not have the necessary permissions, consult with your supervisor or the SAP administrator for guidance.
  
  
  Review Configuration: If this behavior is not expected, it may be worth reviewing the configuration settings in SAP that govern user assignments and processing rules. This may involve checking the relevant authorization objects or customizing settings.
  
  
  Related Information:
  
  Authorization Objects: Check if there are specific authorization objects that control user access to certain transactions or documents.
