Reference column in two structure

Hi,

I need to display the data in following format

   contractno  contract value  quotationno  quotation value

The contract and quotation are coming from same DSO as both are 0document no and they are seprating using document type

if document type = G then it is contract and if B then it is quotation

To acheive this, i created the selection in query with document type for quotation in rows and quotation value in column

When i try to save query i am getting 0document_type used in both structure

I checked about help cells and reference cells, but i am not sure if this will solve my issue

Appreciate your input to fix the issue

Regards

Ben
