Exposing of Advance DSO in HANA using SAP BW 7.5

Hello Experts,

I have created an advance DSO in SAP BW 7.5 using BW perspective of HANA Studio.

I have also checked the SAP External View option.

Issue :-

--------

While trying to import that advance DSO( Import BW meta data option in HANA Studio), The DSO is not seen.

Could you please help me to know the process of exposing advance DSO in bw 7.5 on HANA.

Regards,
