• What is the cause and solution for SAP error message BRF187 - REF_DATE_EXPR: Type conflict: Type "Date" expected, but got &1 ?

  The SAP error message BRF187 indicates a type conflict in the Business Rule Framework (BRF) where a date type is expected, but a different type is being provided. This error typically arises when a rule or expression is trying to evaluate or manipulate a date value, but the input provided does not match the expected date format.
  Cause:
  
  Incorrect Data Type: The most common cause is that the input variable or parameter being passed to the rule is not of the expected "Date" type. For example, it could be a string, integer, or another data type.
  Data Mapping Issues: If the data being passed to the BRF rule is coming from an external source or another part of the application, there may be a mismatch in how the data is being formatted or mapped.
  Rule Configuration: The rule itself may be incorrectly configured, expecting a date but receiving a different type due to logic errors or misconfigurations.
  
  Solution:
  
  Check Input Types: Review the inputs being passed to the BRF rule. Ensure that all parameters expected to be of type "Date" are indeed of that type. You may need to convert or format the data appropriately before passing it to the rule.
  Data Conversion: If the input is in a different format (e.g., string), you may need to convert it to a date format using appropriate functions or methods available in your programming environment.
  Review Rule Logic: Examine the logic of the BRF rule to ensure that it is correctly set up to handle date types. Look for any expressions or conditions that may inadvertently be causing the type conflict.
  Debugging: Use debugging tools available in SAP to trace the execution of the rule and identify where the type mismatch is occurring. This can help pinpoint the exact location of the issue.
