BEx query structure

Hi,

I am trying to query the metadata of a BEx query using XMLA.

While the Key figures, Rows and SAP variables are all returned, if the Rows contain an added structure, it is not returned. What is the request type to query a structure added to Rows?

Any help is appreciated.

I am new to this area so please excuse my lack of knowledge.

Regards,
