Different forecast values between `Forecast` and `DP Forecast` pages

[dfulu]

Describe the bug

When checking the dev dashboard I noticed that the forecast values displayed on the Forecast and DP Forecast pages are different. Screenshot below.

Expected behavior

The forecast values should be the same between pages

DP Forecast page

Forecast page

I'm interested in investigating this bug. I notice the forecast values differ between the two pages, and I'd like to work on identifying the root cause and fixing it. Would you be able to assign me to this issue?

@SaitejaKommi thanks for you interest in this. How did you see they are different? (I think you'll only be able to see this if you have acess to internal ocf databases)

[peterdudfield]

Thanks @dfulu for this, was this just for forecast horizon, or was it also the latest?

I think this might be due to a < and <= in the dataplatform

[dfulu]

Yeh it's the same on latest

[peterdudfield]

if it its <= and < problem, could you look at 60 mins on DP and see if its the same as 30 mins on current platform?

[dfulu]

I've now checked that and they are not the same. I also checked by selecting by creation time and t0 and I can't find forecast pairs that match with that either

[peterdudfield]

Hmm ok. this might need a bit more looking into. At least the latest are the same, so might just need to look into this more

[peterdudfield]

Would you mind looking at a value in the DP forecast page, and then looking to see if you can find that value in the current database?

[dfulu]

Oh sorry, I miscommunicated above. The values are NOT the same on latest. The same issue is present in latest

[peterdudfield]

Oh sorry, I miscommunicated above. The values are NOT the same on latest. The same issue is present in latest

ah ok, are the same for non-adjuster values? I suspect the adjusted values are slightly different as new platform sues rolling 7 days, where as old platform uses values caluclated once a day (for the last 7 days)

[dfulu]

I've only been looking at non-adjusted values. So all the results above are for that

[peterdudfield]

hmm, how odd. Do the future "latest" forecast values look the same?
