Re: [rules-users] Data comparing in CONDITION column decision table

This is true, but be aware that if a cell value in the Template data is empty the whole Fact Pattern is omitted. For example:- rule "Discount @{row.rowNumber}" when Account( $v : @{field} != null ) $c : Customer( @{field} == $v , accno == @{accno} ) then $c.setDiscount(1); end If "field" is empty neither "Account" or "Customer" will be included in the generated DRL. If "accno" is empty "Customer" will not be included in the generated DRL. This may have an impact on what you want to achieve. With kind regards, Mike
