Hierarchy Key Value In WEBI

Hi Experts,

We are using SAP BI 4.1 SP4 and SAP BW 7.3

We have an info object in BW which is set to display key and text both values and there is a hierarchy created on it.

When I use this hierarchy object in WEBI report it displays only text value.

I want to see the KEY values.

Please suggest.

Thanks and Regards,

RS
