How to fix this error?

Be aware that the example given above is showing only one missing
condition, but there may be more. Therefore, we recommend to perform a
completeness check on the decision table, which will display all
existing gaps. You can then select from the conditions that need to be
inserted into the decision table.
Note: This check is based on the table content, not on technical
consistency. Therefore, the check can only make you aware of possible
issues. It is then up to you to judge whether these issues can lead to
real problems or if they may be neglected without risk. You make this
decision based on your business knowledge and the particular
circumstances of the use case for which the decision table has been
defined.
