Travel management- Setting default and max amt for expense types

Hello

In Travel management im trying to set max and default amounts for various expense types as Food,accomodation etc..

For the differentiation of maximum rates within a trip expense type, many parameters are available such as Statutory and enterprise-specific trip types,Trip activity type,Trip country and trip region

If i use any one of the parameters the values are no defaulting in PR05(travel expense manager). If i leave all the parameters as blank the defaults are working

I would like to use one expense type with diff amounts to be defaulted to many ESG. My groupings looks fine and IT0017 also looks fine.

Could someone help?

Regards
