I have an existing Data model with customer name and customer id tables.. Now i have got a new excel to link with it. This excel has some columns.
Major ones are:
Customer ID, Customer Name and Look Up .
Not all Customer Names have a Customer ID. So i want to link this table with my data model using the lookup field like, if there is a Customer ID then through Customer ID and if there isn't a Customer ID, then through Customer name.
Look Up has two values Customer name and Customer Id depending on the lookup type.
