I want to build a excel decision table to implement the logic described as the following drl script: ====== global pricebook.PricingResult result; rule "pricing" when $so : SalesOrder( customer.name=="customer1", from == "location1", to =="location2") *$sol : SalesOrderLine($sol.count >= 0, $sol.count < 100) from $so.lines * then result.setPricingMode("A"); result.setUnitPrice(300.0f); end ====== The java model for the script above is something like this: ====== class SalesOrder{ ... List<SalesOrderLine> lines; ... } ====== In the excel decision table, I defined variables with the following text in excel cells: ====== $so : SalesOrder *$sol : SalesOrderLine ( ) from so.lines* ... ====== The CONDITION column is defined as :* $sol.count >= $1, $sol.count < $2* The decision table is translated into the following drl script: global pricebook.PricingResult result; rule "pricing" when $so : SalesOrder( customer.name=="customer1", from == "location1", to =="location2") * $sol : SalesOrderLine from $so.lines($sol.count >= 0, $sol.count < 100) * then result.setPricingMode("A"); result.setUnitPrice(300.0f); end We can see that* "$soi : SalesOrderLine ( ) from so.lines"* in the excel decision table is translated into* "$sol : SalesOrderLine from $so.lines($sol.count >= 0, $sol.count < 100)" * instead of *"$sol : SalesOrderLine($sol.count >= 0, $sol.count < 100) from $so.lines"*, which causes an error. My question is, how to write the variable definition of SalesOrderLine in excel so that drools can translate it into something like "$sol : SalesOrderLine($sol.count >= 0, $sol.count < 100) from $so.lines " ? Any ideas? Thanks in advance...
