# Description
New model that aggregates in a monthly basis the information from Xero sales. The aggregation is done by several categories, most of them to be included as filters in PBI. Metrics represent the amount without taxes in: 1) the current month, 2) the previous month, 3) twelve months ago, 4) current year YTD (fiscal year) and 5) previous year YTD (fiscal year).
It also propagates the model to reporting
# Checklist
- [X] The edited models and dependants run properly with production data.
- [X] The edited models are sufficiently documented.
- [X] The edited models contain PK tests, and I've ran and passed them.
- [X] I have checked for DRY opportunities with other models and docs.
- [ ] I've picked the right materialization for the affected models. **I was hesitating between table or view. Table should speed up tests, but I intend to create a reporting table with a similar structure so probably a bit of waste of space. Anyway, not a big deal now**
# Other
- [ ] Check if a full-refresh is required after this PR is merged.
