• What is the cause and solution for SAP error message BRF436 - Parameter &1 is missing in function module &2 - see template &3 ?

  The SAP error message BRF436 indicates that a required parameter is missing in a function module that is being called within the Business Rule Framework (BRF+). This error typically arises when the function module is expected to receive certain parameters, but one or more of them are not provided.
  Cause:
  
  Missing Parameter: The most common cause is that the function module defined in the BRF+ rule is not receiving all the necessary parameters. This could be due to a misconfiguration in the BRF+ rule or the function module itself.
  Template Issues: The error message references a template, which may indicate that the template used for the function module is not correctly set up or is missing required parameters.
  Changes in Function Module: If the function module has been modified (e.g., parameters added or removed) after the BRF+ rule was created, it may lead to this error if the BRF+ rule is not updated accordingly.
  
  Solution:
  
  Check Function Module: Review the function module specified in the error message (&2). Ensure that all required parameters are defined and that they match what is expected in the BRF+ rule.
  Review BRF+ Rule: Open the BRF+ application and check the rule that is invoking the function module. Ensure that all parameters required by the function module are being passed correctly.
  Template Verification: Look at the template referenced in the error message (&3). Ensure that it is correctly configured and that all necessary parameters are included.
  Update BRF+ Rules: If there have been changes to the function module, update the BRF+ rules to align with the new parameters.
  Testing: After making the necessary adjustments, test the BRF+ rule to ensure that the error is resolved and that the function module is being called correctly.
