App to manage reference data (slowly changing dimension)

Hi, we have lots of Enterprise data that requires reference data to underpin PowerBi reporting.

Historically uses ftp xls files and these are ingested into the data sat. Over 50% fail due to data errors.

Most are very simple (see example below) so thinking of using PowerApp over sharepoint list (best licencing option).

This list is used a dimension in the data model (using the "slowly changing dimension" framework.

My question is about the rules/mechanism that can best meet the need (preventing overlapping dates).

Example data

Product      Category     From Date     ToDate

bus             transport    01/01/20        01/01/22

tree            plant           01/01/19        01/01/30

bus             vehicle        01/01/21        01/01/25  ** (this being an invalid record)

 

Has anybody any experience of this.. Many Thx
