Evaluate a account defined as TEXT data type

Summary:

hello,

I have one member in the Account dim (dense) defined as a text. I need to evaluate the content of that member in a business rule. I'm hoping with yoru input that there is a function that will allow the business to fix on specific members of the account. Many thanks.

Content (please ensure you mask any confidential information):

This account is called Position and contains text values such as Local Customer, USA Customer, EUR customer, Intl Group, etc
I need to perform calculations based on the value in the member Position.
