Migrating Complex ABAP calculation logic to CDS

sunsapblr — Mon, 18 Jun 2018 08:42:14 GMT

Hi,

Is there any way to migrate the complex calculation logic from ABAP to CDS?

CDS Table function with AMDP cannot be considered as there is no db related calculation.

Also, is there any way to perform the moving average in CDS?

Regards

Sunil

If they're both Turing complete, then yes. There is a way. But probably you'll have to it manually.

Hi Mathew,

Can you please give more clarification?

Thanks & Regards

Anything you can write in a Turing complete language can be written in any other language.

ABAP is Turing complete. So if CDS is Turing complete, then yes, you can migrate one to the other.

My guess is that CDS is not, so it might be possible to migrate or it might not be.

Note, even if you can migrate, that doesn't mean it will necessarily be easy or pretty or efficient.
