External view for Calculation view ADT 2.7 - 2.54

Hi,

We are running BW 7.4 SP5 on HANA and I would in relation to that like to create an External View to consume this calculation view.

However I see that I cant and that ADT 2.7 is required for this - when I then browse the software catalogue on sap marketplace I see that 2.7 hasn't been maintained since 2013 and that it is 2.5 that is being maintained now... I have got 2.54.2 (developer edition) installed.

Hence in total I get a bit confused.

Any idea why that is case and if I at all should create external views to consume HANA artifacts?

Thanks in advance.
