<br>
I have been asked to add default rules to a decision table.<br>
<br>
We have a decision table with several conditions. Data from first two<br>
columns are passed to action with binded variables. The action collects data<br>
from all passed rules.<br>
<br>
-------------------------------------<br>
condition 1 | condition 2 | ... | action<br>
-------------------------------------<br>
AAA | AD | ... | X<br>
-------------------------------------<br>
BBB | AD | ... | X<br>
-------------------------------------<br>
BBB | AE | ... | X<br>
-------------------------------------<br>
BBB | CC | ... | X<br>
-------------------------------------<br>
CCC | AD | ... | X<br>
-------------------------------------<br>
DDD | AD | ... | X<br>
-------------------------------------<br>
BBB | AE | ... | X<br>
-------------------------------------<br>
... | ... | ... | X<br>
-------------------------------------<br>
<br>
Recently business asked me if it is possible to have default rules (rows) in<br>
the table if there is not any rule passing condition 1.<br>
<br>
-------------------------------------<br>
DEFAULT | AD | ... | X<br>
-------------------------------------<br>
DEFAULT | AE | ... | X<br>
-------------------------------------<br>
<br>
Is it possible to have rules in decision table those can be fired only if a<br>
specific part of LHS never occurs in others rules?<br>
<br>
<br>
Thanks in advance,<br>
<br>
