Header changes in input file, how to map standardized header to that field

[wonka1234]

Hi,

My header this week of my input file could be Issue ID 123, next week could be Issue ID 456 and so on.

How can I map this header name to a standard header "Issue ID" all within alteryx?

Thanks.

Add a dynamic rename tool in starting just after input and make 
if Contains([_CurrentField_],"Issue ID") then "Issue ID" else [_CurrentField_] endif

this will work
