Hi Peter,
I suspect the name of the View. It is case sensitive and from the error also, it mentions as "sap.hba.crm/BUSINESSTRANSACTIONTYPE" while the artifact is "sap.hba.crm/BusinessTransactionType".
Quick question, did you browse for the View in the wizard or did you type the name of the View?
With the HANA Studio you can only create Views with upper case.
Kind Regards,
Padma
