• What is the cause and solution for SAP error message FDT_CHANGE_INFO315 - Decision table setting 'allow no match' was set to false ?

  The SAP error message FDT_CHANGE_INFO315 indicates that a decision table setting called "allow no match" has been set to false. This setting is part of the decision table configuration in SAP's Flexible Decision Table (FDT) framework, which is used for business rules and decision-making processes.
  Cause:
  The error occurs when the decision table is configured in such a way that it does not allow for scenarios where no match is found for the input data. When the "allow no match" setting is set to false, the system expects that every possible input will have a corresponding output or action defined in the decision table. If an input is provided that does not match any of the defined rules, the system raises this error.
  Solution:
  To resolve this error, you have a couple of options:
  
  
  Modify the Decision Table Configuration:
  
  If it is acceptable for your business logic to have scenarios where no match is found, you can change the setting of "allow no match" to true. This will allow the decision table to process inputs that do not match any defined rules without raising an error.
  To do this, navigate to the decision table configuration in the SAP system, locate the setting for "allow no match," and set it to true.
  
  
  
  Ensure All Possible Inputs are Covered:
  
  If you want to keep the "allow no match" setting as false, you need to ensure that all possible input scenarios are covered by the rules defined in the decision table. Review the input data and the rules to ensure that there is a match for every possible input.
  
  
  
  Default Action:
  
  If applicable, you can also define a default action or output for cases where no match is found. This can be done by adding a default rule at the end of the decision table that will be executed when no other rules match.
