Entry &1: Currencies/units can only be provided as fixed values

What causes this issue?

In a CDS view annotated with @Analytics.query: true (i.e. the CDS View
is used for generation of a BW Query) you annotated an entry in the
select list with
@Semantics.currencyCode: true or
@Semantics.unitOfMeasure: true
This is supported only if currency or unit are characteristics of the
InfoProvider or are provided as a fixed value.

System Response

The system cannot generate a BW query based on the CDS view.

How to fix this error?

Either remove the select list entry or provide a fixed value - e.g.
cast( 'H' as abap.unit(3) ) as FixUnit
