External SAP HANA view: Key figure '&1': no client-side aggregation

What causes this issue?

The formula contains operators like percentage, the result of which
cannot be aggregated arbitrarily after selecting from the external SAP
HANA view of the BW query.

System Response

In the SAP HANA calculation view, the calculated measure representing
the formula will set the attribute "client-side aggregation" to false.

How to fix this error?

If you want to use the external SAP HANA view of the BW query as a data
source in other SAP HANA views, do not use this calculated measure.
