# Description
This PR ensures the propagation of the dimensions for KPIs across the key aggregating and exposing models. Additionally, provides these 2 new fields in reporting while **not affecting the current data display**, thus it's safe to work in the PBI report without needing to work in 2 PRs in parallel.
**Changes:**
**1 - Intermediate, `int_mtd_vs_previous_year_metrics`:**
* Removes the temporary filter on `where dimension in ({{ production_dimensions }})`. This will be applied directly to reporting later. This ensures that the new dimension on customer segmentation is fully available only within intermediate.
* Adds `dimension` and `dimension_value` granularity. This includes: 1) adding these fields, 2) joining by these fields with all the source CTEs containing the source models with metrics - which in turn needs the change of the dates model - and 3) joining by these fields in the self-join to compute the incremental vs. previous year.
* Changes on the schema file
**2 - Intermediate, `int_mtd_aggregated_metrics`:**
* Adds `dimension` and `dimension_value` granularity. This includes only adding these fields.
* Changes on the schema file
**3 - Reporting, `mtd_aggregated_metrics`:**
* Adds the filter removed on `int_mtd_vs_previous_year_metrics`. This ensures that only the Global dimension is available for the reporting, thus **no changes from user POV**.
* Adds `dimension` and `dimension_value` granularity. This includes only adding these fields
