How to create a ranking logic based on composite provider?

[former_member228516]

Hello Experts,

I have a scenario where, a composite provider (union) is created based on historical adso and hana view. Now I have data where for few document numbers, multiple line items are created as it is present in both info-providers but I need to sort this data based on 'date' and display only the latest document.

I have tried using Virtual Provider, but I am not allowed to create a transformation (and a routine) based on this composite provider. Is there any other way to achieve the same ?

Thanks,

Hi Saurabh,
you could:
a) Create a HANA calculation view which would be Union like the one in composite provider and use rank, then use as a source for composite provider
b) Calculate rank after loading it from composite provider (for example calculate it in Query)
