SAP Fraud Managment; Group Results by Atribute in Frontend

Dear Community,

Together with my team, I am developing and implementing strategies for fraud detection using SAP Fraud Managment. We encounter a problem passing our detection results from the back-end (SAP HANA Studio) to the front-end (SAP Fiori) and could not make progress in solving it.

Consider the following situation:

Our interest lies on a table of transactions (Detection Object):

1 | A | xxx | xxx
2 | B | xxx | xxx
3 | B | xxx | xxx

Now we apply our detection methods (Procedures: SELE, EXEC), resulting in a table with the same structure but only containing fraudulent transactions.

Here the problem Begins: In the SAP Fiori front end, we would like to group the resulting fraudulent transactions in respect to the CLIENTS_ID. This is, we want to generate a list of clients (CLIENTS_ID), that are connected to at least one fraudulent transaction (TRANS_ID) and the ability to connect additional information of those transactions like:

A ------------------------------------------------------------------------------------
1 | xxx | xxx

B ------------------------------------------------------------------------------------
2 | xxx | xxx
3 | xxx | xxx

We failed to define the investigation object. We want the CLIENTS_ID as the hierarchical top ID, but in our list of transactions, it is inevitably not unique and therefore leading to an error because of duplicates . On the other side, If we aggregate on CLIENT_ID to make it unique, we lose important information about our transactions.

Is it possible to display the results in the desired way in the front-end?
If yes, how we need to define the key ID's of investigation and detection object to achieve the desired result?
