Struggling wiht SAP HANA PAL Time series forecasting result tables

Hi,

I have a requirement to create a time series forecast using historical exchange rate but I am really struggling in getting the right values.

I would like to use 1 month historical data to predict next month.

I am working on HANA SPS6 PAL and time series algorithm only allow 2 input fields and result fields and the 2 result fields with INTEGERS TYPE.

My original source table can be seen below.

Since Time series only use 2 rows. I needed to create another table

Below is the forecasted result

despite that I have the forecasted, my requirement is still not met as I needed to have both in 1 tables.

- I cannot create table join as there is no unique key

- I would like to have the currency key and date as integer numbers doesn't make sense.

- and  I would like to be able to compare the actual forecasted value and the predicted.

any idea how I can meet my requirement.

thanks,

Bhat
