  Cause:
  This warning message occurs during the evaluation of a condition or validation in SAP, typically in the context of data entry, business rules, or custom validations (e.g., in transaction processing, user exits, or BRF+ rules). The system evaluates a condition that returns 'true', and as a result, one or more messages (warnings or errors) are triggered.
  
  The &1 placeholder is replaced by the number of messages that exist as a result of this evaluation.
  This message is informational and indicates that the system has found one or more issues or conditions that need attention.
  It often appears in validations, substitutions, or user-defined checks where the system evaluates logical expressions.
