I guess you must use HANA native SQL (so you need to combine with a CDS Table Function and AMDP).

Edit: use the HANA SQL function STRING_AGG.

Hi,

Can I know why do you need such a field where you are concatenating so many items in a single cell.

This will impact heavily on the performance and doesn't look that a CDS view can solve this problem of yours.
