Hi Tanvi,
I think the decision table is the BRFplus expression you are looking for in order to compare some conditions (in your case name/description and amount) to get one (or several) result values.
The single condition columns can have different data types, nevertheless one column is restrited to one data type as it is usually linked to a context variable of your ruleset.
You can also use expressions as columns, but concerning your scenario that would be a litle bit oversized
