• What is the cause and solution for SAP error message WP793 - Display of entire number only with masked credit card number ?

  Certainly! Here's a detailed explanation regarding the SAP error message WP793:
  
  SAP Error Message: WP793
  Text: Display of entire number only with masked credit card number
  
  Cause:
  The error WP793 occurs when there is an attempt to display the full credit card number in a scenario where the system is configured to mask credit card numbers for security reasons. SAP enforces masking of sensitive data such as credit card numbers to comply with data protection and security standards (e.g., PCI DSS).
  In other words, the system is set up to show only masked credit card numbers (e.g., showing only the last 4 digits), but the user or program is trying to display the entire credit card number, which is not allowed.
  
  Explanation:
  
  SAP masks credit card numbers in display and printouts to protect sensitive data.
  The masking is controlled by customizing and authorization checks.
  If a user or program tries to bypass this and display the full number without proper authorization or configuration, the system raises WP793.
  
  
  Solution:
  
  
  Check Authorization:
  
  Ensure the user has the necessary authorization to view full credit card numbers.
  Authorization object: V_VBRK_FKA or similar depending on your SAP version and module.
  If the user lacks authorization, either grant it carefully or restrict access as per company policy.
  
  
  
  Review Configuration:
  
  Check the credit card masking settings in the system.
  In SAP, credit card masking is controlled via IMG path:
  Financial Accounting (New) -> Accounts Receivable and Accounts Payable -> Business Transactions -> Incoming Payments -> Credit Card -> Define Credit Card Types
  
  Also, check the masking rules in the program or report that displays credit card data.
  
  
  
  Program/Report Adjustment:
  
  If you are developing or customizing reports/programs, ensure that the code respects the masking logic.
  Use SAP standard function modules or classes to retrieve masked credit card numbers.
  Avoid direct database access to sensitive fields without masking.
  
  
  
  Use SAP Standard Function Modules:
  
  Use function modules like CRM_CREDIT_CARD_MASK or similar to mask credit card numbers properly.
  This ensures compliance with SAP's masking logic.
  
  
  
  Consult SAP Notes:
  
  Check for any SAP Notes related to WP793 or credit card masking for your SAP version.
  SAP may provide patches or updates to improve masking functionality.
