Store Weekly Snapshots - Incremental refresh or other solution?

[qmartiny]

Hello,

I have been looking for a while and I cannot seem to find a solution for this.

I want to automatically generate weekly snapshots of the same data source (sales pipeline) to use in powerbi for comparison.

Incremental refresh initially looked promising, however :

- I cannot use 'creation week' as the source as other pipeline might go up or down in value outside of that week

I thought I could use dataflows and I have set up a weekly dataflow, but this will only give me the previous week on a rolling basis.

What approaches have you used?

Thank you

Quentin
