How to create a Calculation View on Data from ECC

Hello Experts,

I am trying to create a Calculation View upon the data which i fetched from local ECC system. Below are the procedure followed:

1 . I have pulled MARA table from Local ECC to HCP trial account through Data Services.

2 . MARA table is created under schema  "DEV_"

But when i try to create a calculation view upon those table , am getting error "The following errors occured: user is not authorized (2950)". I have all permission to user "_SYS_REPO" for schema "DEV_"

Can any body help me in this case.

Thanks and Regards,
