I'm on Level 2, Sprint 1, User Story 4 and I'm stuck on creating the DAT04 Distribution Center Parameters Module. What's confusing me is the Time (half-year) dimension.

Am I supposed to leave the regular time dimension in there when i create the module? Here's what i used, to no avail:

I see that the data file for Weekly Safety Stock has in it a field named "Half Year" with 4 values (H1 FY 20, H2 FY 20, H1 FY21, H2 FY21). How do i get this to play with my time dimension?
Any guidance would be appreciated.
