This topic is relevant to SAP Fiori elements for OData V2. For information about SAP Fiori elements for OData V4, see Quick Views: Further Configuration Examples.
Not all columns that are supported in a table support the display of a quick view.

For the currency, no referential constraint is defined by the service. Hence, you need to make the following entry:
<Association Name="assoc_6D52161C1362D99A31996E5BB23202E8" sap:content-version="1">
<End Type="STTA_PROD_MAN.STTA_C_MP_ProductSalesDataType" Multiplicity="1" Role="FromRole_assoc_6D52161C1362D99A31996E5BB23202E8"/>
<End Type="STTA_PROD_MAN.I_CurrencyType" Multiplicity="0..1" Role="ToRole_assoc_6D52161C1362D99A31996E5BB23202E8"/>
<ReferentialConstraint>
<Principal Role="FromRole_assoc_6D52161C1362D99A31996E5BB23202E8">
