Restrict the hierarchy based on Property

Hi,

I'm having one issues about Dimension Override.

I have:

Row:

Product, Vendor.

Columns:

Time, Category etc.

Vendor is attribute/property from Product

I placed the vendor =EPMDimensionPropertyValues(,"PRODUCT","Supplier",J27) using this function

whole vendors are coming into combox.

then I'm using the function =-EPMDimensionOverride("000","PRODUCT",="Vendor= "&J27) which also work fine.

till here no problem, and data is restricted correctly by the vendor I choose in the report.

the issue here is: I have the The Product is a Hierarchy (Members & Children)

when I refresh it.. its only show the the products, do not show me the Product hierarchy with the restricted Vendors, in another words, I want to maintain the hierarchy filter by the chosen vendors.

How can I sort it out?

Thanks.

Regards,
