How to populate increment value from a UDT to the Worksheet Display ?

Content

Our client has a requirement where they do not wish to change the Dynamic values every year and would want to just load the values to a UDT and we should populate the increment percentage based on that.

So we have 3 columns

 

Performance Ratings	Grade	Increment
5	M1	10
4	M1	8
4	M2	9

Is there a way to pull the values of UDT through a fast formula? My developer was telling that it only works where there is only one criteria,eg Grade but when we try to pull a combination of Performance Ratings & Grade,its unable to pull the increment percentages.

Please let us know if we have a solution for this as there is a possibility that we might have to give 3 keys too based on client requirements
