Displaying Dimension On Report??

Hi Guys!!

I have a problem with displaying a Dimension on a report. I am working with PurchPurchaseOrder Report,I have to display the dimension field which is coming from PurchLine table, But report does’t contain this table.

So I wrote display( ) method like this

display Dimension dimensionDisp()

{

return PurchLine::find(VendPurchOrderJour.PurchId).dimension[1]);

}

I drag & dropped on report body, But Its not displaying on the report???

Thanks in Advance!!
