  The SAP error message "EP001 Unauthorized OTHERS instance in CASE instruction '&'" typically indicates that there is an authorization issue related to the CASE statement in your ABAP code. This error occurs when the program attempts to access a CASE branch that the user does not have the necessary permissions for.
  Cause:
  
  Authorization Issues: The user executing the program does not have the required authorizations to access certain data or perform specific actions defined in the CASE statement.
  Incorrect CASE Logic: The CASE statement may be incorrectly structured, leading to an attempt to access an unauthorized instance.
  Missing Roles or Profiles: The user might be missing roles or profiles that grant access to the required objects or transactions.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to check for missing authorizations.
  Review the user's roles and profiles in transaction SU01 or PFCG to ensure they have the necessary permissions.
  
  
  
  Modify the CASE Statement:
  
  Review the ABAP code where the CASE statement is implemented. Ensure that all branches of the CASE statement are valid and that the logic does not lead to unauthorized access.
  If necessary, add checks to ensure that the user has the required authorizations before executing specific branches of the CASE statement.
  
  
  
  Consult with Security Team:
  
  If you identify that the user lacks the necessary authorizations, consult with your SAP security team to request the appropriate roles or adjustments to existing roles.
  
  
  
  Testing:
  
  After making changes to authorizations or the code, test the program again to ensure that the error is resolved.
