  The SAP error message FN520 indicates that a user does not have the necessary authorization to display vendor data for a specific company code. This is a common issue in SAP systems where authorization checks are in place to ensure that users can only access data relevant to their roles and responsibilities.
  Cause:
  The error occurs due to one or more of the following reasons:
  
  Missing Authorization Object: The user lacks the required authorization for the relevant authorization object (e.g., LFB1, LFBK, etc.) that governs access to vendor data.
  Company Code Restrictions: The user may have authorization for some company codes but not for the specific company code indicated in the error message.
  Role Assignment: The user’s assigned roles may not include the necessary permissions to view vendor data.
  Profile Issues: The user profile may not be correctly configured to include the necessary authorizations.
  
  Solution:
  To resolve the FN520 error, you can take the following steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after encountering the error to see which authorization check failed. This will provide insight into what is missing.
  Alternatively, you can use transaction SU01 to view the user’s authorizations.
  
  
  
  Review Authorization Objects:
  
  Identify the relevant authorization objects that control access to vendor data, such as LFB1 (Vendor Master Data) and LFBK (Vendor Bank Data).
  Ensure that the user has the necessary authorizations for these objects, particularly for the specific company code in question.
  
  
  
  Modify User Roles:
  
  If the user lacks the necessary authorizations, you may need to modify their roles or create a new role that includes the required permissions.
  Use transaction PFCG to manage roles and authorization profiles.
  
  
  
  Consult with Security Team:
  
  If you do not have the necessary permissions to change roles or authorizations, contact your SAP security team or administrator for assistance.
  
  
  
  Testing:
  
  After making changes, have the user log out and log back in to test if the issue is resolved.
  
  
  
  Related Information:
  
  Authorization Objects: Familiarize yourself with the relevant authorization objects and their fields. This can help in understanding what specific permissions are required.
  SAP Documentation: Refer to SAP Help documentation for detailed information on authorization management and vendor data access.
  Audit Logs: If necessary, check audit logs to see if there are any patterns or repeated issues with other users.
