Fiori OVP Analytical Card - Error OData Property 'NETPRICEAMOUNTAGGREGATE' already exists

[rb]

Hi,

we have an OData V4 Service and I want to create an OVP with analytical cards. OData is V4 via RAP - No special analytical annotations. 

For my measure NETPRICEAMOUNT I will get the following error on opening the app in the error log:

Property 'NETPRICEAMOUNTAGGREGATE' already exists in entity type 'ET_6FF73BF54300DA439E9DDB6337A'

The aggregate property seems to be automatically generated. Somebody any Idea? 

Best regards Richard
