I have a the following dataframe, let's call it Servers.

`Server <-c("AUSTRALIA", "AUSTRALIA", "AUSTRALIA", "AUSTRALIA", "AUSTRALIA","CHINA","COLOMBIA","COLOMBIA","ECUADOR","ECUADOR","ECUADOR","COREA","COREA","COREA","COREA","BRASIL","BRASIL","BRASIL","ALEMANIA","ALEMANIA","ALEMANIA","ALEMANIA")
Product <- c("021-08183","79P-01747","C5E-00746","7NQ-00302","7JQ-00341","021-08183","021-08183","79P-01747","79P-01747","021-08183","6QH-00002","79P-01747","021-08183","#N/A","6QH-00002","79P-01747","76P-00742","021-08183","021-08183","79P-01747","C5E-00746","7NQ-00302")
Servers <- data.frame(Server, Product)`

It looks like this

What I need is the following. Whenever I have the same value in Server, and the values 021-08183 and 79P-01747, I need to remove the line that has the 021-08183 value, and keep only the one that has 79P-01747.

Output:

Thanks a lot!
