How to Handle a value in a fact table that can have multiple dimension values

Hi everybody my name is jean carlos im new in this forum and new in the world of business intelligence, im working on my first BI project and i want to know how to handle that In the fact table i have there are some records that apply to have more than one value in a dimension table of the model and i need to reflect that for example that a customer have 3 plans in the plan dimension, so i need to know how to count that in every plan.

Thanks in advance for the help.

1 row in the fact table per plan.

You need to define your grain to minimally be Customer, Plan (and probably Date of some kind).

Or add a bridge table between your fact and dimension table.

Here's a link that describes bridge tables. It's essentially an associative entity in normal modeling nomenclature.
