• What is the cause and solution for SAP error message BRF548 - System unable to repair expression &1 (&2) automatically ?

  The SAP error message BRF548 ("System unable to repair expression &1 (&2) automatically") typically occurs in the context of Business Rule Framework (BRF) when there is an issue with a rule expression that cannot be automatically resolved by the system. This can happen for various reasons, such as changes in the underlying data model, missing dependencies, or inconsistencies in the rule definitions.
  Causes:
  
  Changes in Data Model: If there have been changes to the data model (e.g., fields or tables used in the expression have been modified or deleted), the system may not be able to automatically adjust the expression.
