Due date grid for FP04 transaction

Hi Folks,

I need a report layout showing the due date grid for all the open items. Using FP04, I created layouts with all the required fields, but I'm unable to see the grid for due days. Few screenshots of the layout I designed and the summarization fields I defined in our system.

As shown in the output screenshot above, it doesn't display the total grid horizontally for a given customer, instead it is showing rows individually for each grid (30, 60,etc.).

Please advise how this can be fixed to show all the grids for a given customer (30, 60, 90, 180, etc.) in a single row.

Thanks in advance.

Regards,

Santosh
