Impossible to use SAPGETDATA function from an intermediary level of a hierarchy with a cell reference.

Hi Gurus,

It is impossible to use SAPGETDATA function from an intermediary level
of a hierarchy with a cell reference.

When I open completely a hierarchy node I manage to get the bottom level
using a cell reference.

But I cannot do the same thing from a level above.

I attach screenshots.

Best regards,
